Make the YAFFS filesystem work
Recently the YAFFS filesystem support has been added to U-boot. However, just enabling CONFIG_YAFFS2 is not enough to get it working. ymount will generate an exception (when dereferencing mtd->readoob()), because the genericDevice is a null pointer. Further, a lot of logging is produced while using YAFFS fs, so logging should also be disabled. Both issues are solved by this patch. With this patch and CONFIG_YAFFS2 enabled, I get a readable filesystem in U-boot, as well as in Linux. Tested on a Atmel AT91SAM9261EK board.
