This fixes endianness as little for the whole architecture, but xtensa cores may be either little or big endian.
Hi Max,
Thanks for reviewing, I can just add a branch with ifdef CONFIG_SYS_BIG_EDNIAN if you wish, but I think all CPUs U-Boot support are little endian only?
I have an ongoing series[1] fixing endian selection options, please let me know if U-Boot do work with big endian Xtensa.
Thanks.
