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.
