bmpblk: Bitmap sources for firmware UI

Note: Because the bitmaps are stored in RO firmware, back-porting any new bitmaps to already shipped devices is not possible.

Building bitmaps

To build images for board $BOARD with default locales, do:

(chroot) cd ~/trunk/src/platform/bmpblk
(chroot) BOARD="$BOARD" make

To override the locale list defined in boards.yaml (for instance, to build with only English locale to speed up testing flow), pass LOCALES=<locale-list> as an environment variable. For example,

(chroot) LOCALES="en ja es" BOARD="$BOARD" make

The default output folder is ./build/$BOARD. To override output folder, specify OUTPUT=<path_to_output> as an environment variable.

Adding a new target board

Add an entry for the new board in boards.yaml. See the description at the top of boards.yaml. For example, add the following for board link:

link:
  screen: [1920, 1080]
  dpi: 112
  # List of locales to include.
  locales: [en, es-419, pt-BR, fr, es, it, de, nl, da, 'no', sv, ko, he]
  # Right-to-left locales.
  rtl: [he]

Note: The locale no will be interpreted as boolean False in YAML, so we need to quote it as 'no'.

If your configuration is exactly the same as existing ones, add your new board into the existing entry. For example:

asurada,link:
  screen:   [1920, 1080]
  dpi: 112  # DO NOT COPY-PASTE -- follow instructions at top of file.

Bitmaps in firmware image

After emerging chromeos-bmpblk, bitmaps will be stored in the following files:

  1. vbgfx.bin: archive of generic (locale-independent) bitmaps
  2. locale_${LOCALE}.bin: archive of bitmaps for locale ${LOCALE}
  3. font.bin: archive of glyph bitmaps

These archive files for Chromium OS firmware will be created using the archive command from coreboot utils (src/third_party/coreboot/util/archive). These files will end up being stored in the FMAP region COREBOOT in the image.

To show these files in an image $IMAGE, run:

cbfstool $IMAGE print -r COREBOOT

To extract an archive $NAME from an image as $FILE, run:

cbfstool $IMAGE extract -r COREBOOT -n $NAME -f $FILE
