During recent PCI-E tests it has been found that current
driverl level and de-emphasis values are not set correctly.
After sweeping throgh all de-ephasis values, it was found that
0x130 is a right value. Where 0x13 is driver level and 0 is
de-emphasis.

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.

ppc4xx: Cleanup of "ppc4xx: Optimize PLB4 Arbiter..." patch
This patch fixes some minor issues introduced with the patch:
ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika:
- Rework memory-queue and PLB arbiter optimization code, that the
local variable is not needed anymore. This removes one #ifdef.
- Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead
of XXX+ 0x01). This was not introduced by Prodyut, just a
copy-paste problem.
