//! Start-up code for ARMv4 - ARMv6 CPUs that always boot into EL1

// # _default_start
//
// Reset function for ARMv4 to ARMv6
//
// Initialises global memory and sets up stacks. Only supports one CPU core.
//
// This function must produce A32 machine code, because it's called by the Vector Table
// with a raw PC load and the Vector Table is always in A32 machine code.
