Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

initramfs_data includes the compressed binary that is the
|
|
filesystem used for early user space.
|
|
Note: Older versions of "as" (prior to binutils 2.11.90.0.23
|
|
released on 2001-07-14) dit not support .incbin.
|
|
If you are forced to use older binutils than that then the
|
|
following trick can be applied to create the resulting binary:
|
|
|
|
|
|
ld -m elf_i386 --format binary --oformat elf32-i386 -r \
|
|
-T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o
|
|
ld -m elf_i386 -r -o built-in.o initramfs_data.o
|
|
|
|
initramfs_data.scr looks like this:
|
|
SECTIONS
|
|
{
|
|
.init.ramfs : { *(.data) }
|
|
}
|
|
|
|
The above example is for i386 - the parameters vary from architectures.
|
|
Eventually look up LDFLAGS_BLOB in an older version of the
|
|
arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced.
|
|
|
|
Using .incbin has the advantage over ld that the correct flags are set
|
|
in the ELF header, as required by certain architectures.
