There should be no issue of replacing U-boot in SPI nor with the mp30ar0
Tianocore version.
But you need to use the mp30ar0_tianocore_media.img I provide, not the one
supplied
with the Mustang board. It was likely the person burn the wrong BIOS on
the board!
You can burn the Tianocore image from U-boot using TFTP. Please check and
setup your U-boot
variables:
media_addr_r=0x4001000000
media_img=mp30ar0_tianocore_media.img
spi_load=tftp ${media_addr_r} ${user_dir}/${media_img}
spi_update=sf probe 0; sf erase 0x0 ${filesize}; sf write ${media_addr_r}
0x0 ${filesize}
# run spi_load <== Make sure it is successful
# run spi_update
# reset
If there is any issue, it's still recoverable using SD card.

No, not tried it, don't see the point of risking it at the mo. Somebody
did brick their board
(https://lists.centos.org/pipermail/arm-dev/2016-February/001622.html)
and for me, I just chainload tianocore from u-boot via tftp.
