initramfs: generalize variants
Remove initramfs_data.{lzo,lzma,gz,bz2}.S variants and use a common implementation in initramfs_data.S. The common implementation expects the file name of the initramfs to be defined in INITRAMFS_IMAGE. Change the Makefile to set the INITRAMFS_IMAGE define symbol according to the selected compression method. Signed-off-by: Hendrik Brueckner <> Cc: WANG Cong <> Acked-by: Michal Marek <> Acked-by: "H.

- initramfs_data includes the compressed binary that is the
- filesystem used for early user space.
- Note: Older versions of "as" (prior to binutils
- 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:
- .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.
