Hi,
The mp30ar0 U-boot has some special memory mapping to accommodate 32-bit DMA. Please download the tar ball again - I've updated the tianocore UHP for this.

Updated instruction for U-boot chain loading: MP30AR0# setenv num_cores 1 MP30AR0# setenv DDRBASE2G 1 MP30AR0# save; reset
I just did this part and it seems to have semi-bricked the board. It gets as far as: === U-Boot 2013.04 (Jun 02 2015 - 10:54:10)ooREV: 1.15.01-F05 ( uart0 ) ===
and it just stops.
That seems a bit odd from just changing one variable and adding another, I didn't think those were supposed to be read until after the boot interruption prompt.
On to unbricking procedure I go...
Which gets stuck at the exct same point during the boot, only this time it looks like u-boot is a little newer:
=== U-Boot 2013.04-mp30ar0_sw_1.18.04 (Sep 02 2015 - 16:38:06) REV: F06b ( uart0 ) ===
Also tried clearing the CMOS, which made no difference.
Yes, there is a newer u-boot than that shipped. I have used both but I don't remember any advantages with the newer one.
I had an issue whereby I was using the serial console, but had a usb keyboard attached the the MP30 , and the output diverted to the VGA output. Very odd. Hook up a monitor if you haven't done so, just to check.
