This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Dummy function on nios2] Signed-off-by: Tom Rini <trini@konsulko.com>
Rebuilding u-boot for Cyrus The Cyrus defconfigs are Cyrus_P5020_defconfig and Cyrus_P5040_defconfig. They currently disable size optimization in order to avoid a relocation bug in some versions of GCC. As the output size is a constant, the size optimization is not currently important. Cyrus boots off a microSD card in a slot on the motherboard. This requires that the u-boot is built for the Pre-Boot Loader on the P5020/P5040. In order to reflash u-boot, you must download u-boot.pbl, then write it onto the card. To do that from u-boot: > tftp 1000000 u-boot.pbl > mmc write 1000000 8 672 If you want to do this via a card reader in linux: > dd if=u-boot.pbl of=/dev/sdX bs=512 oseek=8
