// The boot entry point is architecture-specific: boot.s on AArch32,
// boot64.s on AArch64 (see each file's header for the differences).

// See mmu_fallback.s: only included when `mmu` is off, so a build of this
// crate never defines `rpi_hal_mmu_init` more than once itself (mmu.rs
// provides its own strong definition when the feature is on). One file per
// architecture, matching the boot stub above.
