[U-Boot] U-Boot ARM/PXA maintainership

[Marek Vasut]

Hello,

It seems my patches for the PXA2xx and PXA3xx in U-Boot are ignored. I'd be 
willing to take over PXA maintainance in U-Boot. I already maintain various PXA-
based devices in mainline Linux kernel. I also maintain the OpenPXA project (IPL 
for PXA3xx devices).

Thanks in advance.
