- Make it actually work
- Split text/data/reloc/rodata sections
- Move hash sections to past end of image
(un-needed in PE)
- Correct section & file alignment
- Correct image size
Builds correctly but untested

The whole gnu-efi project is licensed under BSD license, see [1].
However some of the RISC-V codes have conflict license identifiers:
- Some mention GPL-2.0+ in the SPDX license part, but the long license
header indicates it's actually BSD and GPL-2.0+ dual-licensed
- Some mention GPL-2.0+ in the SPDX license part only
- Some do not have any license indication
To have a matching license with the whole project, this commit updates
all RISC-V codes to have the correct SPDX license identifiers
(GPL-2.0+ or BSD dual-license).

When using function/data sections option from
gcc, some additional un-packed sections get created
move these to there correct placement if not already
included
sections seen on x86/x86_64/aarch64:
.gcc_except_table.efi_main
.bss.debugging
.gcc_except_table.* only appears on objcopy archs

Objcopy sometimes generates .rela.plt and .rela.data
sections for which their names are longer than the 8
characters limit of PE32

Use ld commands DATA_SEGMENT_ALIGN and DATA_SEGMENT_END
Fixes binutils 2.39 warning:
/usr/bin/ld: warning: efi/fwup.so has a LOAD segment with RWX
permissions
Signed-off-by: Callum Farmer <gmbr3@opensuse.org>
The current ld script places .dynamic section right after .text, which
results in that one LOAD segment contains both data and code. Binutils
2.39 and later will throw a warning if RWX segments exist. Code and
data should be placed in different LOAD segments with different
permissions. This patch adds a gap between data and code sections which
is taken from the default ld script in riscv64.
