This fixes endianness as little for the whole architecture, but xtensa cores may be either little or big endian.
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.
I had an impression that there's nothing endian-specific in the xtensa port, so it should work for both little- and big-endian cores. Let me test whether it's true though (:
