[U-Boot] [PATCH 1/6] MIPS: kconfig: add options for endianess select
Daniel Schwierzeck

Sun Oct 26 14:37:51 CET 2014
Add new Kconfig option to let the user select the targets
endianess. Each target have to select SUPPORTS_BIG_ENDIAN
and/or SUPPORTS_LITTLE_ENDIAN to indicate which endianess
is supported.
