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.
The imx6.dtsi is incomplete, but has enough to support devices that work
right now. Eventually it will need to be split into several files that
account for the differences between SoCs in the imx6 family.
The board config for Wandboard Dual is untested. Solo and Quad work, but
one one core is turned on for the quad right now (baby steps).
than one unit with four busses attached to it. This allows us to use
existing fdt data which describes separate devices with separate resources.
It also allows any combination of the units to be en/disabled in the
board dts files.
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
comment block in the driver, so I don't have to re-learn it for the next
round of changes.
All Armada XP chips should be affected. It is necessary to handle
busy interrupt/indication by enabling busy-detect property in DTS.

Switch the majority of device configuration to FDT from hints.
Add BERI_*_BASE configs to reduce duplication in the MDROOT and SDROOT
kernels.
Add NFS and GSSAPI support by default.

The TI uart hardware is ns16550-compatible, except that before it can
be used the clocks and power have to be enabled and a non-standard
mode control register has to be set to put the device in uart mode
(as opposed to irDa or other serial protocols). This adds the extra
code in an extension to the standard ns8250 probe routine, and the
rest of the driver is just the standard ns8250 code.
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.
Add support for A20 timer.
Correct interrupt offset depending from chip.
Add basic code for CPU configuration module.
For now, add kernel config and dts file
(only FDT blob related problem needs to be solved later in
order to have one kernel for both cubieboard1 and 2).

Add a new .dts for the BeagleBone Black with more memory,
slightly different pinmux initialization, and with mmchs1
configured (though the latter doesn't quite work yet).

- window initialization is done during device attach
- CESA TDMA decoding windows values are set based on DTS,
not copied from CPU registers
- remove unnecessary virtual mapping

functionality
- Update interrupts property of dma node to contain all allocated
interrupts
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.

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
MSI are implemented via software interrupt. PCIe cards will write
into software interrupt register which will cause inbound shared
interrupt which will be interpreted as a MSI.

- Add functions to calculate clocks instead using hardcoded values
- Update reset and timers functions
- Update number of interrupts
- Change name of platform from db88f78100 to db78460
- Correct DRAM size and PCI IRQ routing in dts file.
