From: Babu Moger <babu.moger@xxxxxxxxxx> Subject: arch/microblaze: add choice for endianness and update Makefile microblaze architectures can be configured for either little or big endian formats. Add a choice option for the user to select the correct endian format(default to big endian). Also update the Makefile so toolchain can compile for the format it is configured for.
