[U-Boot] [PATCH v3 10/12] OMAP3: Add SPL support to omap3_evm
Tom Rini

Wed Nov 9 18:11:04 CET 2011
Add Hynix 200MHz timing information to <asm/arch-omap3/mem.h>. We
don't calculate the MCFG value here for the Micron parts as the provided
one assumes a memory size which is incorrect. This also changes
CONFIG_SYS_TEXT_BASE to 0x80100000.
