Detailed Description

aarch64: setting up the kernel, from where boot/head.S jumps to, up to kmain(), in the order that docs/kernel/booting.md's table gives (as x86's x86_cpu_init() does).

Function Documentation

◆ aarch64_init()

void aarch64_init ( uintptr_t dtb )

Sets up the CPU, memory and the platform, then calls kmain().

boot/head.S jumps here once the MMU is on. It doesn't return.

Parameters

dtb	the devicetree's physical address, from the boot loader
