- Make libreboot (all of it!) build reproducibly. This is very important.
- See <a href="http://projects.mtjm.eu/work_packages/16">http://projects.mtjm.eu/work_packages/16</a>.

- <li>
- Add information from hw registers on all boards. See
- <a href="http://projects.mtjm.eu/work_packages/15">http://projects.mtjm.eu/work_packages/15</a>
- </li>
- <li>
- Reduce the size of libreboot releases.
- See <a href="http://projects.mtjm.eu/work_packages/19">http://projects.mtjm.eu/work_packages/19</a>

- <ul>
- <li>
- add roda rk9 support (contact nico to ask for more details about hw).

- </li>
- <li>
- port acer aspire 5738 to coreboot (gm45)? (and then libreboot). EC is the main blocker (no support in coreboot yet).
- ME isn't an issue, because its GM45 so it could be removed (it looks like this machine might also be shipped in
- non-descriptor mode by default, like the roda rk9).
- Search <b>jv50 block diagram filetype:pdf</b> for schematics.
- (jv50 is written on the board); noone seems to have found any documentation for the EC chip, but
- maybe it could be sufficiently reverse engineered via serialice and ectool.
- </li>
- <li>
- T400S and X301. These both seem to be GS45. X301 uses only the low-performance mode CPUs, so raminit
- is the main blocker there. They both probably use WSON-8 flash chips.
- </li>
- <li>
- Add proper GS45 raminit for enabling all X200S and X200 Tablets to work properly. (maybe other machines)

+ <ul>
+ <li>
+ linux 3.18 broke acpi brightness on i945 (X60/T60). Libreboot reverted to legacy brightness for now. Look into why it

- <li>
- Look into the possibility of expanding libreboot to support non-coreboot systems. (u-boot, for instance).
- Currently, libreboot presents itself as a deblobbed coreboot distribution. There are other systems out there
- that use other firmware, such as u-boot, which libreboot could theoretically support. This would mean that
- the build scripts know how to build things other than just coreboot/grub.
- <ul>
- <li>Allwinner A10 (ARM) SoCs</li>
- <li>PMON?</li>
- <li>barebox (u-boot derivative)</li>

- <li>
- .spd.hex files. These aren't blobs? Don't remove them? (in coreboot). See deblob script.

- This is talking about without native init / oprom. Paul reported it, look into it.
- i945 currently lacks fake_vbt tables.
- </li>
- <li>
- Make ich9gen/ich9deblob portable. They both rely extensively on bitfields, and they assume
- little-endian; for instance, mapping a little endian file directly to a struct, instead
- of serializing/deserializing. Re-factor both utilities and make them fully portable.
