From 7ee05eddf184764de8aa1e015936a42d069893f2 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Thu, 26 Apr 2018 09:35:13 +0200 Subject: util/cbfstool: Support FIT payloads In order to support booting a GNU/Linux payload on non x86, the FIT format should be used, as it is the defacto standard on ARM. Due to greater complexity of FIT it is not converted to simple ELF format. Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'. The payload is included as is, with no special header. The code can determine the type at runtime using the CBFS_TYPE field. Support for parsing FIT payloads in coreboot is added in a follow on commit. Compression of FIT payloads is not supported, as the FIT sections might be compressed itself. Starting at this point a CBFS payload/ can be either of type FIT or SELF. Tested on Cavium SoC.
