bug report: fail to boot barebox in marvell 6281 board

[you xiaojie <84640926@qq.com>]

I ported barebox to a new board similar to guruplug, but it could not boot, 
only show a line of barebox 2020.03.0-....., and I try official guruplug also 
stopped. the devicetree is ok under linux 5.4 and the kwbimage.cfg is ok I 
think, according to the 6281's datasheet and compared with the original 
register value of machine.

so any can try guruplug's barebox? this is my porting patch, is there 
something wrong?
