dbc7fdc681 - Fix BBB's dts compilation with GNU dtc 2014-03-02 06:36:49 +00:00
Ian Lepore
bc837fc0c0 Prevent fdt data loaded from a file from overwriting the kernel environment,
by having uboot_autoload() do the fdt setup (which may load a file) rather
than waiting until we're actually in the process of launching the kernel.

As part of making this happen...
 - Define LOADER_FDT_SUPPORT on the uboot/lib compile command line when
   MK_FDT is set.
 - Make fdt_setup_fdtb() public.
 - Declare public fdt_whatever() functions in a header instead of using
   scattered extern decls in .c files.

eeb913c99f Integrate device-tree upstream files into the build process:
(1) Invoke cpp to bring in files via #include (although the old
    /include/ stuff is supported still).
(2) bring in files from either vendor tree or freebsd-custom files
    when building.
(3) move all dts* files from sys/boot/fdt/dts to
    sys/boot/fdt/dts/${MACHINE} as appropriate.
(4) encode all the magic to do the build in sys/tools/fdt/make_dtb.sh
    so that the different places in the tree use the exact same logic.
(5) switch back to gpl dtc by default. the bsdl one in the tree has
    significant issues not easily addressed by those unfamiliar with
    the code.

b85b1bbd0f Enable the second and the third I2C controllers on Beaglebone-black.
The first I2C controller is only used to manage the on-board devices (PMIC
and HDMI framer) and its bus is not exposed on the expasion headers.

With this change the following pins on the P9 expansion headers are now
reserved as I2C pins:

 Pin 17 - I2C1 SCL
 Pin 18 - I2C1 SDA
 Pin 19 - I2C2 SCL
 Pin 20 - I2C2 SDA

The I2C2 is the bus that should be used to read the contents of cape
eeproms.

abe4be7dfd Add a feature for automatically finding and loading a dtb file by name.
The name is taken from the u-boot env vars fdtfile or fdt_file.  If the
name isn't fully-qualified a search is done in module_path locations.

The search order for a usable dtb in fdt_setup_fdtp() is now

 - A dtb loaded with an explicit "load -t dtb" command.
 - A dtb already loaded into memory somehow[*] and pointed to by fdt_to_load.
 - A dtb in the memory pointed to by the u-boot env vars fdtaddr or fdt_addr.
 - A file named by the u-boot env vars fdtfile or fdt_file.
 - A static dtb compiled into the kernel.

* Presumably by some arch-specific command or code.

d000dd2f86 Change fdt_setup_fdtp() from "guess then fail" to more probe-like behavior.
The old code basically said it was going to use some particular blob
without knowing whether it could successfully do so, then it would invoke
the function to do that and return its status.  If it failed, you were
done, even if other blobs might be available.  Now the code attempts to use
some particular blob and if that succeeds it says so and returns success,
otherwise it moves on to try another potential blob.

One specific problem this solves is when u-boot sets an fdtaddr variable
to point to some memory address, then doesn't actually load a blob at
that address.  Now the header check will fail, and the code will move
on to the fallback dtb compiled into the kernel (if any).

7c674742cb Look for both fdtaddr and fdt_addr env var names. Grepping the u-boot
source shows that board vendors seem to be about evenly split on this.

This commit is a trivial change to note that while the previous change
was supposed to be whitespace only, this functional change also crept in.
The added lines were:

  /* Board vendors use both fdtaddr and fdt_addr names.  Grrrr. */

  if (s == NULL)
	s = ub_env_get("fdt_addr");

86a5575402 Add basic cpu frequency control and temperature monitoring to imx6_anatop.
The temperature monitor device is enabled to sample the die temperature at
16hz.  The temperature is published via sysctl.  A callout routine at 10hz
monitors the temperature and throttles back the cpu if the temperature
goes over a user-settable throttle point (by default 10C less than the
critical high-point temperature for the chip).  The hardware is supposed
to be able to deliver an interrupt when the temperature exceeds a settable
limit, but the interrupt never arrives so for now a callout does the job.

At attach time we read the maximum cpu frequency the chip is allowed to run
at and the cpu is set to run at that speed.  It's reported at attach time.
A sysctl variable reports the current speed when queried.

New sysctl values:

  dev.imx6_anatop.0.cpu_mhz: 984
  dev.imx6_anatop.0.temperature: 37.9C
  dev.imx6_anatop.0.throttle_temperature: 95.0C

4a98e46950 TI sdhci driver improvements, mostly related to fdt data...
Use the published compatible strings (our own invention, "ti,mmchs" is
still accepted as well, for now).

Don't blindly turn on 8-bit bus mode, because even though the conroller
supports it, the board has to be wired appropriately as well.  Use the
published property (bus-width=<n>) and honor all the valid values (1,4,8).

The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts.

The mmchs controller can inherently do both 1.8v and 3.0v on the first
device and 1.8v only on other devices, unless an external transceiver is
used.  Set the voltage automatically for the first device and honor
the published fdt property (ti,dualvolt) for other devices.

Thanks go to Ilya Bakulin for figuring out the voltage compatibility stuff.

It also allows any combination of the units to be en/disabled in the

Adjust our dts code to match what's used by linux and u-boot now that
we're structured to do so.

Document lots of interesting stuff learned whiling doing this with a big

The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a
couple quirks, which are now supported by sdhci(4) as of r254507.

This should work for all TI SoCs that use the MMCHS hardware, but it has
only been tested on AM335x right now, so this enables it on those platforms
but leaves the existing ti_mmchs driver in place for other OMAP variants
until they can be tested.

This initial incarnation lacks DMA support (coming soon).  Even without it
this improves performance pretty noticibly over the ti_mmchs driver,
primarily because it now does multiblock IO.

7554e820bb Attach the elf section headers to the loaded kernel as metadata, so
they can easily be used by later post-processing.  When searching for
a compiled-in fdt blob, use the section headers to get the size and
location of the .dynsym section to do a symbol search.

This fixes a problem where the search could overshoot the symbol
table and wander into the string table.  Sometimes that was harmless
and sometimes it lead to spurious panic messages about an offset
bigger than the module size.

I've left one final COPYIN() to update the in-kernel DTB

3bb97cef07 "fdt addr" gets run from loader.rc before the kernel is loaded.
This was broken by r247045 which tried to copy the FDT into the
module directory immediately.
Instead, store the address and arrange for the FDT to get
copied into the module directory later when the usual
FDT initialization runs.

f87223581e Fix "fdt addr" to accept literal addresses rather than va offsets.
When initializing the fdt, query U-Boot as well.

With this change, it is now feasible to have U-Boot load
the FDT, ubldr will pull it from U-Boot and hand it to the
kernel.

ecfc48a031 Add support for the GlobalScale Technologies DreamPlug computer.
This adds support for version 10, revision 01, but it should also work
without changes for the 0901 model, at least until we get drivers for the
two different wifi chips involved.

Many users contributed to and tested the various patchsets floating around
for the past year that have eventually evolved into this checkin, most notably
Richard Neese who provided the bulk of the kernel config file.

ee9b837148 - Implement "fdt mres" sub-command that prints reserved memory regions
- Add "fdt addr" subcommand that lets you specify preloaded blob address
- Do not pre-initialize blob for "fdt addr"
- Do not try to load dtb every time fdt subcommand is issued,
    do it only once
- Change the way DTB is passed to kernel. With introduction of "fdt addr"
    actual blob address can be not virtual but physical or reside in
    area higher then 64Mb. ubldr should create copy of it in kernel area
    and pass pointer to this newly allocated buffer which is guaranteed to work
    in kernel after switching on MMU.
- Convert memreserv FDT info to "memreserv" property of root node
    FDT uses /memreserve/ data to notify OS about reserved memory areas.
    Technically it's not real property, it's just data blob, sequence
    of <start, size> pairs where both start and size are 64-bit integers.
    It doesn't fit nicely with OF API we use in kernel, so in order to unify
    thing ubldr converts this data to "memreserve" property using the same
    format for addresses and sizes as /memory node.

ab11b7079a Make FDT blob compatible with Raspberry Pi firmware.
Rasperry Pi firmware has a set of hardcoded pathes it uses to fill
FDT with system-specific information like display resolution, memory
size, UART and SDHCI clocks, ethernet MAC address. Handle two of them:

- Add placeholder for ethernet MAC address
- Move display node out of "axi" node
