rk3188 (radxa rock pro) boot failure w/ barebox 2018-04 and later

Hey list,

Between 2018-04 and 2018-05 tar release, barebox stops booting on rk3188 
(radxa rock pro).

A git bisect reveals (see end of mail for commit detail): 
	first bad commit: [2a94e821ba2e64890ac47b9ba177c7b6585b23be] ARM: For 
relocatable image force TEXT_BASE 0x0.

As was suggested on #barebox, I tried setting TEXT_BASE=0x10 at this commit 
but it's a no fix. 

It is however booting even later releases if the trailing "if !RELOCATABLE" is 
removed. I have yet to have a deeper look at the code modified by 
HAVE_CONFIGURABLE_TEXT_BASE and RELOCATABLE.

Furthermore, it seems the commit itself is only triggering a boot failure. The 
proper code causing it is probably hiding someplace else.

Any direction, ideas or hints given is appreciated.

Thanks.

cheers

S.

    ARM: For relocatable image force TEXT_BASE 0x0
    
    Nothing else should be used for the relocatable image case, so
    force TEXT_BASE to 0x0 and do not show it in the menu.
