accordingly.

0239c2fb4a i.MX28: Improve passing of data from SPL to U-Boot
Pass memory size from SPL via structure located in SRAM instead of SCRATCH
registers. This allows passing more data about boot from SPL to U-Boot, like the
boot mode pads configuration.

96666a39ae DMA: Split the APBH DMA init into block and channel init
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:

c944a3ef82 i.MX28: Move SPL to arch/arm/cpu/arm926ejs/mx28
This moves SPL to common location so it can be reused by multiple boards. Also,
this commit adjusts M28 SoM to avoid breakage due to the move.

aa72e43bb7 MXS: Add static annotations to dma driver
Some functions were internal to the apbh dma driver, so annotate them static.
Some of the functions weren't used at all so drop them. This makes the U-Boot
binary smaller by about 1500 bytes.
