Thanks for the fixups. I integrated your additions/suggestions into the
RATP branch. See -next for the result. I also fixed the compile breakage
with CONFIG_RATP disabled.

[RFC] usb: port UHCI driver from the u-boot

[pmamonov]

From: Peter Mamonov 

Here is a UHCI driver ported from the u-boot.
There are a few pending FIXMEs, but the driver should work.

Can anyone test it?

BINDING:
uhci: uhci@ {
compatible = "generic-uhci";
reg = <0x 0x200>;

/* specify companion EHCI controller if any */
companion = <>;
};

I can't see any build failures here. which config/branch are you using?

[PATCH] bootm: Add option to force booting signed images

[Sascha Hauer]

With CONFIG_BOOTM_FORCE_SIGNED_IMAGES the bootm code will refuse to boot
unsigned images. Since currently FIT is the only image type which
supports signing this means we with this option we enforce using FIT
images. All additionally passed in device trees and initrds will be
ignored so that only the ones from the FIT image can be used.
