Initial AArch64 port ( #205 )
...
* Initial aarch64 port
* Enable chainload on aarch64
No changes necessary since it's all UEFI anyway.
* Add specification for Limine protocol for aarch64
* PROTOCOL: Specify state of information in DT /chosen node
* common: Add spinup code for aarch64
* common: Port elf and term to aarch64
* common: Port vmm to aarch64
Also prepare to drop VMM_FLAG_PRESENT on x86.
* protos: Port limine boot protocol to aarch64
Also drop VMM_FLAG_PRESENT since we never unmap pages anyway.
* test: Add DTB request
* PROTOCOL: Port SMP request to aarch64
* cpu: Add cache maintenance functions for aarch64
* protos/limine, sys: Port SMP to aarch64
Also move common asm macros into a header file.
* test: Start up APs
* vmm: Unify get_next_level and implement large page splitting
* protos/limine: Map framebuffer using correct caching mode on AArch64
* CI: Fix GCC build for aarch64
* entry, menu: Replace uses of naked attribute with separate asm file
GCC does not understand the naked attribute on aarch64, and didn't
understand it for x86 in older versions.
