Alexey Brodkin from Synopsys says in [1]: I think indeed, we may remove all the big-endian support for ARC. Reasons are since introduction of ARC HS4x processors we no longer support big-endian in any new processor IP, and even for older IP which used to support big-endian it was rarely used... so basically there's no good justification to spend any cycles on big-endian support looking forward in this project. I.e. BE support in uClibc could also be removed if it makes any difference. Therefore, let's removed support for ARC big-endian.
