CONFIG_ISA_ARM

Type: bool
Help
From: https://developer.arm.com/products/architecture/instruction-sets/a32-and-t32-instruction-sets
A32 instructions, known as Arm instructions in pre-Armv8 architectures,
are 32 bits wide, and are aligned on 4-byte boundaries. A32 instructions
are supported by both A-profile and R-profile architectures.
A32 was traditionally used in applications requiring the highest
performance, or for handling hardware exceptions such as interrupts and
processor start-up. Much of its functionality was subsumed into T32 with
the introduction of Thumb-2 technology.
