applied to u-boot-mips, thanks. Stefan, because CONFIG_NR_DRAM_BANKS was converted to Kconfig in mainline, I needed to run moveconfig.py on your patch series. I committed all changes on the defconfig files which removes things like your SPI driver and SPI-NAND support. I think a "make savedefconfig" should always produce the same result. You should send follow-up patches to enable those features after they are merged to mainline. -- - Daniel
