[U-Boot] [PATCH] i.MX28: Fix VDDIO and VDDA setup

[Robert Deliën]

Hi,

Same here. I've applied the patch and tried it on my mx28evk and 'reboot' from the
Kernel prompt results into DRAM: 0 Bytes and a hanging U-Boot.

I didn't try single-stepping with the debugger yet; I'm still messing around
with the PLL bypass bit and PLL configuration.

Cheers,

        Robert.

Tried your patch and my mx28evk still hangs after a "reboot" command.
It reads the scratch registers as 0, report the total RAM size as 0
and then U-boot hangs.
