[U-Boot] Load kernel from UbiFS or YAFFS2

[Thorsten Mühlfelder]

Hi,

does U-Boot already support loading the kernel of a UbiFS or YAFFS2
partition? I've built U-Boot 2010.09 for an Atmel at91sam9260ek_nandflash 
board and I've seen that there are some ubi sources included but the U-Boot 
binary does not offer any ubi related commands, such as ubifsload.
Similiar question for YAFFS2.

Greetings
Thorsten
