7b8657e2bd ARM: mxs: Receive r0 and r1 passed from BootROM
Make sure value in register r0 and r1 is preserved and passed to
the board_init_ll() and mxs_common_spl_init() where it can be
processed further. The value in r0 can be configured during the
BootStream generation to arbitary value, r1 contains pointer to
return value from CALL'd function.

This patch also clears the value in r0 before returning to BootROM
to make sure the BootROM is not confused by this value.

Finally, this patch cleans up some comments in the start.S file.

ddfcc810d3 mx28evk: Convert to mxs_adjust_memory_params()
Recent conversion from mx28_adjust_memory_params to mxs_adjust_memory_params
missed to update mx28evk, which caused the board not to boot.

Apply the conversion so that the board can boot again.

f69b0653ac mx28evk: Fix boot by adjusting HW_DRAM_CTL29 register
commit acc4959fc1 (Revert "i.MX28: Enable additional DRAM address bits")
broke mx28evk boot.

Fix it by properly adjusting the HW_DRAM_CTL29 register value.

ecb7be2985 mx28evk: add NAND support
NAND support is not enabled by default because Eval Kit is not delivered
with NAND chip. To enable NAND support add CONFIG_CMD_NAND to board config.

ed97abed27 mx28evk: add SPI support
This patch adds SPI support for the MX28EVK. Support for
an optionally installed SPI flash is also added. An example
configuration for redundant envrionment from SPI flash is also
added but disabled by default.

This patch has been tested on a MX28EVK Rev. D with an installed
SST25VF032B 32Mbit SPI flash.
