[PATCH 4/4] memory: fix memory calculation

[Alexander Aring]

Hi,

Thanks, I will do this changes.
Move fixes as first and separte the fix calculation patch in fixes for
'request_sdram_region' and 'printouts of iomem at boottime', which is only
necessary for correct eyecandy.

Sry, It's true to get all information from iomem, never used this command :)
I got ideas to improve my other patches... I will try to insert it, too.

I send this mail from my private mail address...
My phytec address doesn't work with the barebox mailinglist.

Regards
Alexander Aring
