X-Git-Url: http://git.ipfire.org/?p=people%2Fms%2Fu-boot.git;a=commitdiff_plain;h=5f9c58e97e5e21380315cb42cffca6c6aa2c8383

arm: baltos: fix NAND boot

Specify proper U-Boot offset, enable prefetch mode,
increase bootm size and add FIT fallback, if board_name
is not present in kernel-fit.itb image.
