ARM926EJS: Make asm routines volatile in cache ops

2012-04-16T20:11:57+00:00

We certainly don't want the compiler to reorganise the code for dcache flushing.

MX35: mx35pdk: wrong board revision

2012-04-16T12:53:59+00:00

The board revision is detected accessing to the pmic,
that is not available before relocation (I2C).
This generates the following error:

CPU:   Freescale i.MX35 rev 2.0 at 532 MHz.
Reset cause: WDOG
 = 7 is invalid. Should be less than 0
Board: MX35 PDK 1.0

The revision number is wrong, as a default value is printed
(tested on a mx35pdk Rev. 2.0).

Move the output in the board_late_init(), when
pmic can be accessed.

ARM1136: MX35: Make asm routines volatile in cache ops

2012-04-16T12:53:59+00:00

As well as pushed for ARM926EJS, we certainly don't want
the compiler to reorganise the code for dcache flushing
Fix checkpatch warnings as well.

ARM: add u-boot.imx as target for i.MX SOCs

2012-04-16T12:53:59+00:00

Freescale SOCs require an header to u-boot.bin

The patch adds u-boot.imx to the default targets
if the imx file is set (IMX_CONFIG).

M28: Pull out CONFIG_APBH_DMA so it's always enabled

2012-04-16T12:53:59+00:00

The ABPH DMA is now used also by the SD card. Therefore it has to be enabled
even if NAND is disabled.

DMA: Split the APBH DMA init into block and channel init

2012-04-16T12:53:59+00:00

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

NOTE: This patch depends on:

imx: Return gpio_set_value in gpio_direction_output

2012-04-16T12:53:59+00:00

Return gpio_set_value in gpio_direction_output.
Earlier it returned 0 and ignored gpio_set_value's return value.
