This patch series adds UBI support to U-Boot:
UBI (Latin: "where?") stands for "Unsorted Block Images". It is a volume
management system for flash devices which manages multiple logical volumes on
a single physical flash device and spreads the I/O load (i.e, wear-leveling)
across the whole flash chip.
In a sense, UBI may be compared to the Logical Volume Manager (LVM). Whereas
LVM maps logical sectors to physical sectors, UBI maps logical eraseblocks to
physical eraseblocks. But besides the mapping, UBI implements global
wear-leveling and I/O errors handling.

The changes in this version are:
- Added "ubi part" command to dynamically configure
the UBI partitions to "work" on.
- Remove board_ubi_scan(). Not needed anymore because of the more
flexible common "ubi part" command.
- Fixes for non-UBI builds.
- Removed some compiler warnings
- More codingstyle cleanup.
This version is available in the "testing" branch of the u-boot-ubi
repository.
Best regards,
Stefan
