--------------------------------+------------------------------
For debugging of the EFI loader we added a static 16K buffer for storage
of logs (as is done in the BIOS loader). This buffer is not initialized so
it should be in the .bss section (to be cleared at program
initialization). However we found out that the generated EFI file became
larger according to the size of the buffer.
This likely means the BSS segments are included inside the binary, and we
end up with a larger than needed loader, filled with zeros.
We should review the linker scripts and conversion to PE format to make
sure the bss segment is not included in the binary, and if needed, add the
startup code to allocate and clear it.
