2019-03-05cbfstool: Change FMD annotation to flagsHung-Te Lin
The idea of "annotation" for firmware sections was pretty flexible, but in future we will want multiple attributes applied to same area. For example, indicate the section must be preserved when updating firmware so serial number or MAC address can be preserved. The solution here is to extend annotation so it can take multiple identifiers (flags) in a row. For example, to declare a 64KB COREBOOT section as CBFS using annotation: COREBOOT(CBFS)@0x0 64k If there's a new flag "PRESERVE" indicating the section must be preserved before update, we can declare it following CBFS flag: COREBOOT(CBFS PRESERVE)@0x0 64k The flags are directly parsed in fmd_parser, and stored in an union flashmap_flags. Output modules can choose to ignore or process the flags. Currently the only supported flag is "CBFS" (for backward compatible with annotation). There will be more new flags in follow up patches.

2015-05-08fmaptool: Introduce the fmd ("flashmap descriptor") language and compilerSol Boucher
This adds a compiler for a language whose textual representation of flashmap regions will be used to describe the layout of flash chips that contain more than just a single CBFS. Direct integration with cbfstool (via a new command-line switch for the create action) is forthcoming but will be added separately. BUG=chromium:461875 TEST=Use Chromium OS's cros_bundle_firmware script on the fmap.dts file for panther. Using the latter file as a reference, write a corresponding fmap.fmd file and feed it through fmaptool. Run both binary output files though the flashmap project's own flashmap_decode utility. Observe only the expected differences.
