Why? This way we don't need to recompile the image when the size of the LinuxBIOS image changes. This alows building images for 50 motherboards and equipping each with 10 payloads, resulting in 500 images while you only have to build each payload once and each motherboard, too. There's also a small "fix" allowing the compression type to be case insensitive. Not really relevant I guess. Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Ronald G.

LinuxBIOS Archiver: lar ----------------------- Table of Contents - Introduction - Usage - Archive format - TODO - Copyright and License Introduction ------------ This is a simple archiver, similar to cpio, ar or tar. Design goals were - minimum overhead - maximum fault tolerance - simplicity For a usage example see example.c. For questions contact Stefan Reinauer <stepan@coresystems.de>. Usage ----- Create archive archive.lar containing files file1 ... fileN: $ lar c archive.lar file1 ... fileN Extract files from archive.lar: $ lar x archive.lar [file1 ... fileN] List files in archive: $ lar l archive.lar Archive format -------------- The rough format is: |--------------| | header | |--------------| | data | |--------------| | header | |--------------| | data | |--------------| ... Headers have to be 16 byte aligned. |----------------------------| | magic (8 bytes) | |----------------------------| | length (4 bytes) | |----------------------------| | checksum (4 bytes) | |----------------------------| | offset to blob (4 bytes) | |----------------------------| | "path name" | <-- null terminated, aligned to 16 bytes |----------------------------| | blob (aligned to 16 bytes) | |----------------------------| TODO ---- - Reading flash layouts - This does not enforce any alignment yet - Alignment enforcing will be optional Copyright and License --------------------- Copyright (C) 2006-2007 coresystems GmbH Written by Stefan Reinauer <stepan@coresystems.de> for coresystems GmbH.
