I just sent additional patches
(http://patchwork.ozlabs.org/project/uboot/list/?series=5892) to fix
the 'make tests' issues.

Please do the following on the u-boot-usb/master branch:

1). Drop http://git.denx.de/?p=u-boot/u-boot-usb.git;a=commit;h=198db64035a589ef19920b2cec58419b4b338ce7
2). Drop http://git.denx.de/?p=u-boot/u-boot-usb.git;a=commit;h=9a462a3af216d77fee689f119419506218531f77
3). Apply http://patchwork.ozlabs.org/project/uboot/list/?series=5892
on top of u-boot-usb/master

Then everything should be fine.

Regards,
Bin
