w00t!  Thanks Lorenzo.  I'll look through and make comments.  There
have been quite few changes since Jeremy's dtbimage branch.  In
particular the amba bus clock changes are taking a bit to rework.
I've also cherry picked most of Jeremy's patches (everything except
imx51) and have also made a number of changes.  For the next spin it
would be a good idea to use my test-devicetree branch as the base.

I'm currently reworking the device tree breakage caused by amba clock
support, and then I'll be pushing out my branch updated to 2.6.36-rc1
later this afternoon.

Cheers,
g.
