=== Week 13 === * MMC driver ready - adapted from BeagleBoardPkg. * Created a wiki[1] containing file descriptions and build process (please review). * Code cleanup: duplicates removed.
=== Next (Post-GSoC) === * Load 3.16 Kernel on BBB using EFI stub support.

=== Week 12 ===
- BDS now loads
- UefiShell available
- The boot sequence is: MLO -> PrePi -> DxeCore -> BDS -> (EBL or Shell.efi)
=== Next ===
- Add MMC support
- Document what has been done
- Add PMIC + RTC support

=== Week 11 ===
- DxeCore now loads
- Fixed PcdGet() issue by correcting PcdFdBaseAddress according to SPL
- DEBUG() works
- InterruptDxe, TimerDxe, WatchdogTimerDxe and TimerLib added
=== Next ===
- Add BDS dependencies, launch BDS
- Document
- Depreceate Sec and PrePeiCore since using PrePi, cleanup build spec
files.
Thanks, Varad

=== Week 9, 10 ===
- Since memory is already initialized by SPL, launch from PrePi.
- Place TexasInstrumentsPkg into edk2 [1].
- PCD issue from Week 7 - in BeagleBoardPkg as well - thread: [2]
=== Next ===
- Fix PcdGet() (maybe a toolchain problem)
- Get DEBUG() working
- Load DxeCore.

=== Week 8 ===
- Load PrePeiCore from U-Boot's SPL. Sec not needed.
- Documented the work so far [1]
=== Next ===
- Pass through PEI, construct HOBs and jump to DXE
This is fun!

=== Week 7 ===
- Issue with DEBUG(): internal assertions fail and macro returns.
(proper PCDs and Libraries used)
- Issue with SerialPortWrite(): strings with >4 characters fail to
print. (am waiting for TX FIFO to clear before sending in the next char)
- Added PEI phase to SEC itself (as done in BeagleBoardPkg).
- Better option: Have a separate PEI phase (follow D01 instead of
BeagleBoard). Using ArmPlatformPkg/PrePeiCore; figure out how to jump.
- Issue with PcdGet32(PcdFvBaseAddress): returns 0 for valid
PcdFvBaseAddress
=== Next ===
- Fix the issues listed (figure out why PCDs not showing up)
- Load PEI

=== Week 6 ===
- Built Shell.efi with BeagleBoneBlackPkg
- Could not launch from SEC; dependencies unmet. Need to follow SEC
-> DXE -> BDS -> Shell.efi
- Added DXE call to BeagleBoneBlackPkg
=== Next ===
- Get DXE debug output from the board.
