[U-Boot] [PATCH 0/2] Add support for MINI2440 (s3c2440)

[Marek Vasut <marex@denx.de>]

Dear Gabriel Huau,

Even without looking, I sense flaws ... I sense fluctuations in the patch-force 
;-)

So let's get to it :-)

We discussed it, didn't we ? The SRAM is only mapped at different place. So drop 
the support for nand booting altogether and re-add it when you have it fixed.
