Release 4.11 arch/arm/include/asm/swab.h
/*
* arch/arm/include/asm/byteorder.h
*
* ARM Endian-ness. In little endian mode, the data bus is connected such
* that byte accesses appear as:
* 0 = d0...d7, 1 = d8...d15, 2 = d16...d23, 3 = d24...d31
* and word accesses (data or instruction) appear as:
* d0...d31
*
* When in big endian mode, byte accesses appear as:
* 0 = d24...d31, 1 = d16...d23, 2 = d8...d15, 3 = d0...d7
* and word accesses (data or instruction) appear as:
* d0...d31
