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.

3fec2c677e imx: m53evk: Convert to iomux-v3
There is no change of behavior, except for the folloing line that has been
removed because the iomux mode was not set accordingly and the pad used for OTG
OC is not this one:
	mxc_iomux_set_input(MX53_USBOH3_IPP_IND_OTG_OC_SELECT_INPUT, 1);

72f8ebf17e mxs: Rename 'mx28_dram_init' to 'mxs_dram_init'
The DRAM initialization, after SPL has complete, is exactly the same
for all mxs SoCs so we should name it accordinly.

The following boards has been changed:

 * apx4devkit
 * m28evk
 * mx28evk
 * sc_sps_1

22fe68fbdc iMX28: Fix ARM vector handling
This patch introduces proper ARM vector handling for i.MX28 CPU. This issue
wasn't addressed because the interrupts weren't enabled on any ARMv5 core,
therefore the issue wasn't noticed earlier.

In previous implementation, the vectoring code used by i.MX28 CPU when an
exception happened was that of the SPL. With this change, the branch target when
an exception happens can be reconfigured by U-Boot.
