Move the declaration for mpentry() into a header file instead of pasting
it into a bunch of different .c files.
If the L2 cache type is PIPT, pass a physical address for a flush.
Actually set the proper bit to indicate TTB shared memory.
Add a new cache maintenance function, idcache_inv_all, to the table, and
implementations for each of the chips we support.
Invalidate caches immediately upon entry to init_secondary(). Also set
the Bufferable bit in the PDE entries of the secondary processor startup
pagetables.
Add the bits needed to run SMP on imx6.
Invalidate the SCU cache tag ram on all 4 cores, not just 1-3.
Minor tweaks to the imx GPT timer
Vybrid enhancements...
- Pin configuration is a complete iomux register now and includes
drive strength, pull mode, mux mode, speed, etc.
- Add i2c devices to the tree
- Add IPG clock
- Add support for Quartz Module.

r262355, r262419,
Add Vybrid driver for Synchronous Audio Interface (SAI).
Decrease SAI buffer size. Handle eDMA interrupt on running channel only.
Give the physmem fdt helper routines static linkage since no global
definition of them is provided anywhere.
Add imx6 early printf support, wrapped in #if 0 because it's rarely needed.
Add basic cpu frequency control and temperature monitoring to imx6_anatop.
Add the FREEBSD_BOOT_LOADER option so that a loaded DTB passed in from
ubldr will actually get used.
Create a generic IMX6 kernel config, then fix it to have an ident line.
Don't force imx6 bootverbose on anymore, it can be set from ubldr now.
r261955, r261958,
Add a driver to provide access to imx6 on-chip one-time-programmble data.
Make it possible to access the ocotp registers before the ocotp device
is attached, by establishing a temporary mapping of the registers when
necessary.
It turns out Freescale cleverly made the ocotp device compatible across
several different families of SoCs, so move it to the freescale directory
and prefix everything with fsl rather than imx6.
Convert the imx6 sdhci "R1B fix" from a busy-loop in the interrupt handler
to a callout.
Increase the wait time for acquiring the SD bus from 10 to 250ms.
If no compatible cards were found after probing the SD bus, say so.
Add timeout logic to sdhci, separate from the timeouts done by the hardware.
After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA
rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing
any possibility of recovering from the error.
Add a helper routine to depth-search the device tree for a node with a
matching 'compatible' property.
r261848, r261855
On armv6 and later, use the WriteNotRead bit of the fault status register
to decide what protections are required by the faulting access.
Use the right symbols for determining arm architecture. Include the
necessary header file which has the new FAULT_WNR symbol defined in it.
Allow the kernel to be loaded at any 1MiB address. This requirement is
because we use the 1MiB section maps as they only need a single pagetable.
Add function for configuring Vybrid PLL4 (Audio) clock frequency output.
imx6 changes ...
- Fix the definition of the SDHCI_STATE_DAT and SDHCI_STATE_CMD fields,
and add SDHCI_RETUNE_REQUEST. None of these are actually used in the
code yet.
- Write translation code for the SDHCI_PRESENT_STATE register.
Freescale moved some bits around in their version of the register,
adjust things so that the sdhci code sees the standard layout.
- Add standard non-removable and cd-gpios properties to the usdhc
devices. That generates references to gpio devices, so uncomment them
even though there isn't a gpio driver to do anything with them yet.
- Add handling of standard "non-removable" property, and also some
workaround code so that if card detect is wired to a gpio pin, for now
we just treat it the same as non-removable (because there isn't a gpio
driver yet).
- Enable both sdcard slots, but not the sdio-based wifi that we don't
yet have a driver for.
- Remove a couple obsolete function declarations.
Remove FreeBSD 6 support from atmel usb controllers.
Add Vybrid drivers for:
- Enhanced Direct Memory Access Controller (eDMA)
- Direct Memory Access Multiplexer (DMAMUX)
r261596, r261606
Add the imx sdhci controller.
Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.
Add the missing ')' at end of sentence. Reword it to use a more common idiom.
Pass the kernel physical address to initarm through the boot param struct.
Make functions only used in vfp.c static, and remove vfp_enable.
Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to
place 32-bit data in r1, not r0. 64-bit data is already packed correctly.
Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us
remove the need to load the kernel at a fixed address.
Remove references to PHYSADDR where it's used only in debugging output.
Dynamically generate the page table. This will allow us to detect the
physical address we are loaded at to change the mapping.
Add support for Colibri VF50 Evaluation Board.
Add driver for Display Control Unit (DCU4).
Add prototype for tcon_bypass() used by dcu4.
Add register definition.
o Expand device tree information
o Export iomuxc (pins) configuration to DTS
o Allow devices to assign clocks in DTS
o Split kernel configuration to chip common and board specific parts.
r261353
Fix the name of the dts file for the HL201...
When mapping an address, the bsh needs the same offset we do for other things.
Add explicit depends on bus_if.h and device_if.h to avoid a
chicken and egg problem in some compilation environments.
Switch to using PAs rather than VAs for the addresses we map for
devices. This is a nop, except for what's reported by atmelbus for the
resources.
Comment cleanups. Move things around for diff reduction against FDT work.
Add configuration for the Freescale i.MX53 Quick Start Board.
Add the Raspberry Pi BSC (I2C compliant) controller driver.
Add Radxa Rock board (by radxa.com) support.
Digi-CCWMX53: enable ffec and uart, USB.
Add support for Freescale Vybrid Family VF600
Move and rename dwc otg driver to more generic one as it appears to work
for rk3188 SoC based board too.

Add common bus_space tag definition shared for most supported ARMv6/v7 SoCs.
Correct license statements to reflect the fact that these files were all
derived from sys/arm/mv/bus_space.c.
In pmap_unmapdev(), remember the size, and use that as an argument to
kva_free(), or we'd end up always passing it a size of 0
In pmap_mapdev(), first check whether a static mapping exists,
Convert TI static device mapping to use the new arm_devmap_add_entry(),
Use the common armv6 fdt_bus_tag defintion for tegra instead of a local copy.
Eliminate use of fdt_immr_addr(), it's not needed for tegra
Convert lpc from using fdt_immr style to arm_devmap_add_entry() to make
static device mappings.
Retire machine/fdt.h as a header used by MI code, as its function is now
obsolete. This involves the following pieces:
- Remove it entirely on PowerPC, where it is not used by MD code either
- Remove all references to machine/fdt.h in non-architecture-specific code
(aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat
non-arch-specific).
- Fix code relying on header pollution from machine/fdt.h includes
- Legacy fdtbus.c (still used on x86 FDT systems) now passes resource
requests to its parent (nexus). This allows x86 FDT devices to allocate
both memory and IO requests and removes the last notionally MI use of
fdtbus_bs_tag.
- On those architectures that retain a machine/fdt.h, unused bits like
FDT_MAP_IRQ and FDT_INTR_MAX have been removed.
Add #include <machine/fdt.h> to a few files that used to get it via pollution
Enable the mv cesa security/crypto device by providing the required property
in the dts source, and adding the right devices to the kernel config.
Remove dev/fdt/fdt_pci.c, which was code specific to Marvell ARM SoCs,
related to setting up static device mappings. Since it was only used by
arm/mv/mv_pci.c, it's now just static functions within that file, plus
one public function that gets called only from arm/mv/mv_machdep.c.
Switch RPi to using arm_devmap_add_entry() to set up static device mapping.
Allow 'no static device mappings' to potentially work.
Don't try to find a static mapping before calling pmap_mapdev(), that logic
is now part of pmap_mapdev() and doesn't need to be duplicated here.
Switch a10 to using arm_devmap_add_entry() to set up static device mapping.
r257794, r257795, r257992
Teach nexus(4) about Open Firmware (e.g. FDT) on ARM and MIPS, retiring
fdtbus in most cases.
Make OF_nextprop() work correctly for FDT by using the libfdt
fdt_next_property_offset() API.
Do not panic if pmap_mincore() is called.
An addendum: it is possible, though of questionable utility, for a node
to have no properties at all.
Add definition for the Atheros 8021 gigabit PHY.
Consolidate Apple firmware hacks and improve them by switching on the
presence of mac-io devices in the tree, which uniquely identifies Apple
hardware.
Allow OF_decode_addr() to also be able to map resources on big-endian
devices.
Make tsec work with the device tree present on the RB800.
Be more flexible about which compatible strings to accept. This brings up
the PCI Express bus on the RB800 using the firmware device tree.
Rename the "bare" platform "mpc85xx", which is what it actually is, and
add actual platform probing based on PVR.
Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.
Similar to the (1 << 31) case it is not defined to do (2 << 30).
This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.
A similar change was made in OpenBSD.
Call initarm_lastaddr() later in the init sequence, after establishing
static device mappings, rather than as the first of the initializations
that a platform can hook into. This allows a platform to allocate KVA
from the top of the address space downwards for things like static device
mapping, and return the final "last usable address" result after that and
other early init work is done.
Because some platforms were doing work in initarm_lastaddr() that needs to
be done early, add a new initarm_early_init() routine and move the early
init code to that routine on those platforms.
Make PTE_DEVICE a synonym for PTE_NOCACHE on armv4, to make it easier to
share the same code on both architectures.
Add new helper routines for arm static device mapping. The new code
allocates kva space from the top down for the device mappings and builds
entries in an internal table which is automatically used later by
arm_devmap_bootstrap(). The platform code just calls the new
arm_devmap_add_entry() function as many times as it needs to (up to 32
entries allowed; most platforms use 2 or 3 at most).
Remove imx local devmap code and use the essentially identical common
code that got moved from imx_machdep.c to arm/devmap.c.
Begin reducing code duplication in arm pmap.c and pmap-v6.c by factoring
out common code related to mapping device memory into a new devmap.c file.
Remove the growing duplication of code that used pmap_devmap_find_pa() and
then did some math with the returned results to generate a virtual address,
and likewise in reverse to get a physical address. Now there are a pair
of functions, arm_devmap_vtop() and arm_devmap_ptov(), to do that. The
bus_space_map() implementations are rewritten in terms of these.
Move remaining code and data related to static device mapping into the
new devmap.[ch] files. Emphasize the MD nature of these things by using
the prefix arm_devmap_ on the function and type names (already a few of
these things found their way into MI code, hopefully it will be harder to
do by accident in the future).
Revamp the SoC identity numbering scheme to be more in line with the way
Freescale numbers the chips in the ID registers.
Add definitions for the register and data that describes the SoC type.
Reset the timer interrupt status register at the top rather than bottom of
the interrupt handler. If the event callback starts a new short timeout,
the timer can fire before returning from the event callback, and clearing
the interrupt status after that loses the interrupt and hangs until the
counter wraps. Fixing all of this removes the need for the do-nothing
loop at the top of the handler which really just waited for the counter to
roll over and reach the one-shot count again.
Also add a missing return(0) in the periodic timer start case.
Expand the list of compatible devices this driver works with. Increase
the target frequency from 1 to 10 MHz because these SoCs are plenty fast
enough to benefit from the extra event timer resolution.
Remove all #include <machine/pmap.h> from arm code. It's already
included by vm/pmap.h, which is a prerequisite for arm/machine/pmap.h
so there's no reason to ever include it directly.
Remove #include <machine/frame.h> from all the arm code that doesn't
really need it. That would be almost everywhere it was included. Add
it in a couple files that really do need it and were previously getting
it by accident via another header.
Remove the last dregs of trapframe_t. It turns out only arm was using
this type, so remove it to make arm code more consistant with other
platforms.
Maximize available kva space by doing static device mapping from the top
of the address space downwards, and then returning the lowest mapped
device address from initarm_lastaddr(). Premap most of the device's
on-chip peripherals.
Add a driver for the Freescale Fast Ethernet Controller found on various
Freescale SoCs including the i.MX series. This also works for the newer
SoCs with the ENET gigabit controller, but doesn't use any of the new
hardware features other than enabling gigabit speed.
Mask out non-address bits in the mac address register, for proper
detection of an all-zeroes address. Also remove a misplaced return.
Switch to using ofw_bus_search_compatible() table-driven compat lookup.
Add compat strings for Freescale Vybrid family SoCs.
Instead of hard-coding the uart register addresses for the imx51, use
a variable that defaults to the imx51 address. When debugging another
imx-family SoC, the variable can be set early in initarm() to provide
full console/printf support for debugging early boot.
