I just updated the NAND custodian git repository. It got completely reset 
because I had to restructure the master branch to not include the new MTD 
infrastructure for now. So I suggest, anybody using the u-boot-nand-flash 
custodian repository should clone this repository from scratch.

Here is the new repository layout:

master branch:
Changed, additions and bug fixes to the current "stable" nand subsystem

mtd-2.6.22.1 branch:
Merge of the Linux 2.6.22.1 MTD subsystem with additional changes and YAFFS2 
support

But please keep on testing the new mtd branch and please also send fixes for 
the still missing/broken issues, so that we can merge it into mainline in the 
not too far future.

Thanks.

Best regards,
Stefan
