Some of the wrapper routines (printf, fprintf, etc) were defined in
stdio.c which is not necessarily compiled with the same compiler flags
concerning floating point support.
On some architectures (arm64, x86-64) this caused the wrapper routines
to clobber the floating point registers prior to getting into the
printf_engine.
Added platform_setup_system_table, where platform/vendor can
make arbitrary changes to UEFI's system table, overriding
any of the UEFI protocols with custom one.
This allows other components to reference basic UEFI types. Now
different platforms can provide their own override for certain UEFI
protocols.
To keep good include structure, all public headers are put under
include/uefi.
This function was previously put in anon namespace, making it
unavailable for other source files to consume. Since we made this
function an API for consumption, move outside anon namespace so
that linkers can find it.
A large pile of changes to the PC platform and x86 architecture that
facilitate SMP support. Tested in both 64 and 32bit on qemu and real
hardware all the way back through i486.
For LK_DEBUGLEVEL > 1
> alloc_struct_begin_size: 24
> free_heap_chunk_size: 24
size: max(alloc_struct_begin_size, free_heap_chunk_size)
But when freeing the chunk, allocated size is expected to be
greater than size of free_heap_chunk struct.
It contradicts its own code.
So add >= instead of > to maintain the integrity between
allocation and freeing of memory chunk.

GCC 14 is quite picky about warnings, probably more so than clang.
-Fix a bunch of printf warnings. Pointers should be printed with %p.
-Move some stuff into an anonymous namespace.
-Worked around GCC really not liking reinterpret_casting from one
function pointer type to another. Fiddled with it a bit and eventually
settled on casting the function pointer to const void * and passing it
through.
This change updates the `help` console command to list the available
commands alphabetically, but only when we're not panicking. This makes
`help`'s helping more helpful.
This loads all sections specified by PE header at the correct memory
location, and executes the entry point function. Only the
OutputString function of text output protocol is implemented,
so the only application we can run is hello world.

Thids adds a uefi_load <block dev name> command, which will
parse the PE header and do some basic validation checks.
