[PATCH 08/34] ARM OMAP boards: switch to barebox_arm_entry
Sascha Hauer
s.hauer at pengutronix.de
Sun Jan 27 05:46:37 EST 2013
All boards use hardcoded SDRAM addresses, copied from the board init file.
OMAP3 boards are a bit special, they had a SoC specific reset() function. This
is renamed to omap3_invalidate_dcache() and called from the board lowlevel init
code now.
