[U-Boot] [PATCH 3/7] Add support for SRAM Boot

2010-08-16 Thread Haiying Wang
Once CONFIG_MIDDLE_STAGE_SRAM_BOOT is defined, CONFIG_SRAM_BOOT is enabled to generate u-boot-sram.bin which will run in the l2/l3 sram. This middle stage uboot will init ddr sdram with ddr spd code and load the final uboot image to ddr and start from there. It is useful for the silicons which have
