2011-12-09i.MX28: Move SPL to arch/arm/cpu/arm926ejs/mx28Marek Vasut7-1581/+6
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. Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Cc: Wolfgang Denk <wd@denx.de> Cc: Detlev Zundel <dzu@denx.de> Cc: Stefano Babic <sbabic@denx.de>

2011-11-11M28EVK: Enable USB HOST supportMarek Vasut1-0/+7
This enables the second port, aka. the port with the USB connector on the M28EVK. Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Wolfgang Denk <wd@denx.de> Cc: Detlev Zundel <dzu@denx.de> Cc: Remy Bohmer <linux@bohmer.net>
2011-11-11M28: Add memory detection into SPLMarek Vasut3-3/+49
This code allows the DDR DRAM size to be detected at runtime. The RAM size is stored into two scratch registers, from which it is then fetched in U-Boot.

2011-11-11iMX28: Fix ARM vector handlingMarek Vasut1-213/+51
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.
