734996820f [MIPS] Malta: Handle byteswapping hardare bug in big endian mode.
The SOC-it system controller running in big endian mode might forget
byteswapping when DMAing to the last word of physical memory.  Fixed by

466e6227e6 [ARM] 3588/1: AT91RM9200 CSB337/637 board update
Patch from Andrew Victor

This patch updates the support for the Cogent CSB337 and CSB637 boards.

The changes include:
1. Use the new at91_uart_config structure and device registration
functions for the UARTs.
2. Registration of I2C and SPI platform devices.
3. The CSB337 board uses PB0 & PB1 (and not PB2) for the LEDs.  [Patch

82c583e3ae [ARM] 3587/1: AT91RM9200 hardware headers
Patch from Andrew Victor

These headers define the registers and bits for the SPI (Serial

UDP (USB Device) peripherals integrated in the AT91RM9200 processor.

(They will probably also be usable for the AT91SAM9 series of SoC

Patch from Andrew Victor

This patch updates the platform device support for the AT91RM9200.

The changes include:

1. USB Host device renamed to "at91_ohci" since the driver is also
usable on the AT91SAM9261 processor.
2. Enabling multidrive on the USB Device's pullup pin should not be done
for all boards.  Moved into board-specific files.  [Patch from David
Brownell]
3. Move enabling of PCMCIA/Compact Flash pins out of the driver.
4. Added SPI device and resources.
5. Added Watchdog device and resources.  [Patch from David Brownell]
6. Added UART device and resources.
7. The simple devices (watchdog, rtc, i2c) are now automatically
registered and don't have to be registered separately in each
board-specific file. [Patch from David Brownell]

9df5db80a7 [ARM] 3534/1: add spi support to lubbock platform
Patch from David Brownell

This adds the platform device for SSP/SPI controller, and declares
the ads7846 device hooked up to it.  Not all Lubbock boards appear
to populate the connector needed to use this instead of the ucb1400
chip, but it can always be used as a temperature sensor.

In short, this is probably most useful as an example of how to
provide the configuration data used by the pxa2xx_spi driver.
(Last tested against a slightly earlier version of that driver.)

5247593c96 [ARM] 3335/1: Old-abi Thumb sys_syscall broken
Patch from Paul Brook

The old-abi sys_syscall syscall is broken when called from Thumb mode. It
assumes the syscall number is an Arm syscall number (ie. starts from
__NR_OABI_SYSCALL_BASE).  In thumb mode syscall numbers start from zero.

The patch below fixes this by clearing the nigh bits of the syscall number
instead of inverting them. Technically this means we accept some invalid
syscall numbers, but I can't see how that could be a problem. The two sets of
numbers far apart that unimplemented syscalls should still be rejected.
