apm821xx: use lzma compression for the initramfs images
The MR24's u-boot takes it sweet time decompressing the LZMA-packed initramfs image. A user reported that compared to the old gzip method in v2: it "takes a ton longer to decompress like 4\x the old boot time for decompression". This patch also fixes a issue with the WNDR4700's initramfs image getting to big and causing the following u-boot crash during the decompression: "Uncompressing Multi-File Image ... Error: inflate() returned -5 out-of-mem or overwrite error - must RESET board to recover" This patch fixes both issues by reverting the MR24's initramfs compression method back to gzip. And choosing to compress the initramfs within the initramfs image as LZMA by default. Cc: chrisrblake93@gmail.com Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
