u-boot crash on T2080RDB_SPIFLASH

[Chris Packham]

Hi,

Just tried out v2020.10-rc3 on my T2080RDB and I've got the following
splat. Haven't had a chance to decode it yet (pointers on how to
translate the addresses for powerpc welcome) but I figured I'd get
this out just in case anyone was looking at the T2080RDB.

SPI boot...
