omap3 bootrom emulation

small changes in boot rom code

- update comments and include a note for r12=1 smc call
- leave the cpu in SYS mode when jumping to bootloader code

Signed-off-by: Juha Riihimäki <juha.riihimaki@nokia.com>

Changes by: Loïc Minier <loic.minier@linaro.org>
Fix use of p after free() in omap3_mmc_fat_boot()
Fix logic test to use && in omap3_mmc_fat_boot

Changes by: Peter Maydell <peter.maydell@linaro.org>
Remove code which was erroneously overriding the detection of a CHSETUP
header in an OMAP boot image loaded from an MMC card.
Fix raw mode boot (try sectors 0 and 256, use right offsets)

Changes by: Juha:
- do not map boot rom at address zero
- make use of the arm cp15 vector base address register
- run boot rom emulation from omap3 instead of board

Changes by: Peter Chubb <peter.chubb@nicta.com.au>
