Change in flashrom[master]: Move endianness definitions and provide it inside Makefile
by Nico Huber (Code Review) 01 Dec '17

Nico Huber has uploaded this change for review. ( https://review.coreboot.org/22670 Change subject: Move endianness definitions and provide it inside Makefile ...................................................................... Move endianness definitions and provide it inside Makefile Add an `endiantest.c` similar to `archtest.c` to provide the endianness inside the Makefile. The __FLASHROM_(LITTLE|BIG)_ENDIAN__ definitions had to move from `hwaccess.h` into `platform.h`, therefor. This will be used to decide whether to build the internal programmer in a follow- up.
