[U-Boot] [PATCH v2 0/2] Fix TQM8560 DDR boot issue

[Becky Bruce]

Series to fix the TQM85xx issue reported by Wolfgang.... the problem
turned out to be that those boards use get_ram_size(), which requires
that a TLB entry be set up for the DDR region.  My earlier patches
changed the way this was done and broke this.

I've created a new function, clear_ddr_tlbs(), so that there is now a
setup_ddr_tlbs() and a matching clear_ddr_tlbs() that boards can use
if they need to temporarily set up a TLB entry for this purpose.  The
tqm85xx ddr init code now uses this and the board is able to boot.

NOTE: There was another patch in this series that changed some include
logic in the TQM85xx.h header file.  I have dropped that patch as it
was screwed up and not needed.

Cheers,
Becky
