9c60b66f71 AARCH64: Allow for embedding an initramfs
This actually breaks the armv7 port. It has to be revisited in the
future, since it not only is not compilable right now, but also
cannot boot linux properly. TODO

Also introduce a new C-based __memcpy_optimized that does not
cause an exception on some devices when copying the initramfs.
This issue has to be debugged further.

784bfd609a lib: unic: Optimize memcpy and memset for aarch64
Move onto using asmdefs macros in assembly files. Implement an
assembly-based memcpy for aarch64 and a C-optimized memset, while
also making place for replacing functions with more optimized ones
in the future.

3ab64bed39 lib: Introduce unic
unic is a small library of C functions that is currently written
in plain C. It's purpose isn't to be fast, but "universal" - as
in include as little architecture-specific code as possible.

The old neatlibc still resides, but isn't being built. There is
still more to do, including implementation of memory management,
so keep it there for now.

54d3d93a92 arch: aarch64: Set up Stack Pointer
Introduce stack and bss memory regions, rename Start.S to start.S
This commit should allow jumping out of assembly code for certain
SoCs that had issues with SP like MTK and QCOM.

4a0977b0f6 lib: Replace the broken newlib implementation with neatlibc
Make 2 different folders for armv7 and aarch64 assembly neatlibc
functions. Add the neatlibc submodule, make it work against the
Makefile system. Pray.

b37e225721 arch: arm: Implement TEXT_BASE instead of using a hardcoded address
This was an issue for other armv7 boards that have slightly different
addresses till now. This also allows to start working on relocation
in the near future for both armv7 and aarch64.

While we're at it, fix some mistakes here and there.
