Re: Volunteer for "Add FFS support to U-Boot"

[berte <behzaterte%yandex.com@localhost>]

Hey Jared,

I've done with task01-02 you can find those changes into same repository ufs_task01_02_code_review tag.

:::: Task summary ::::
- Add an ffs driver to U-Boot (read-only)  -> done
- Add the following commands to U-Boot: ffssize, ffsload, ffsls -> done
- Integrate changes with existing U-Boot packages (sysutils/u-boot*) in pkgsrc -> wip
- Update armv7.img to support booting directly from FFS. -> tba
- Modify sysinst to allow for installation without an MSDOS partition.  -> tba
    Some of this will be SoC-specific. Need to detect the SoC type and select the correct kernel/dtb and adjust partition layout    to not interfere with U-Boot / SoC specific bootloaders.

Cheers,
--berte.
