bec0806cfe spi_s3c24xx: add FIQ pseudo-DMA support
Add pseudo-DMA by FIQ to the S3C24XX SPI driver.  This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.

Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch).  We expect most users are loading this via udev and thus
there should be no change to the userland configuration.

9f05f6a921 [ARM] S3C24XX: GPIO: Remove pin specific input and output defines
The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are
very rare and are taking up large amounts of space in the
regs-gpio.h header.

The GPIO layer has had generic input and out defines called
S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work
for all S3C24XX GPIOs.

Do the following replacements:

   S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT
   S3C2410_GP[A-Z][0-9]*_\INP  => /S3C2410_GPIO_INPUT
   S3C2410_GPA[0-9]*_OUT       => S3C2410_GPIO_OUTPUT

to remove any usages of these and prepare the header for
the removal of these.

The following command was used to acheive this:

find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g'

a8af6de00f [ARM] S3C2410: mach-bast.c registering i2c data too early
The BAST support code is calling s3c_i2c0_set_platdata() from
the map_io() entry, instead of the bast_init() code. This causes
the registration to fail due to kmalloc() not being available
at the time.

This fixes the following error:
s3c_i2c0_set_platdata: no memory for platform data
