Yes, the architecture permits single-endianness implementations
(in which case SCTLR.SED is RES1, and the various other
endianness controls are RES0 or RES1 depending on whether
the CPU is always-little-endian or always-big-endian). It also
permits "EL0 is mixed-endianness but EL1/2/3 are always
big/little endian". (See the "Mixed-endian support" section
in the v8 ARM ARM.)
