[U-Boot] [PATCH] arm: mvebu: turris_omnia: Use thumb instructions in SPL to save space

[Marek Behún]

Stefan,

thanks for this. My workaround for this was to increase
CONFIG_SPL_SIZE from 140 KiB to 160 KiB, in
include/configs/turris_omnia.h.
But yours works as well. Perhaps we should do both if the image
increases in the future...
