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

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).

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:

ARM: 926ejs: use debug() for misaligned addresses

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

Misaligned warnings are useful to debug faulty drivers.
A misaligned warning is printed also when the driver
is correct - use debug() instead of printf().

ARM1136: add cache flush and invalidate operations

2012-04-16T12:53:58+00:00

Since commit 5c1ad3e6f8ae578bbe30e09652f1531e9bc22031
(net: fec_mxc: allow use with cache enabled) the FEC_MXC
driver uses flush_dcache_range() and invalidate_dcache_range()
functions. This driver is also configured for ARM1136 based
'flea3' and 'mx35pdk' boards which currently do not build
as there are no ARM1136 specific flush_dcache_range() and
invalidate_dcache_range() functions. Add various ARM1136
cache functions to fix building for 'flea3' and 'mx35pdk'.
