neither does the OMAP3 ROM code. All the cargo cult around geometry stems
from the fact that initially x-loader aka MLO hardcoded sector 63 for the
start of the boot partition and this is fixed since long. Unfortunately,
there is a large number of ancient unfixed MLO files out there...
I think we can count that as arcarna... but I think we're talking about
different problems, and that the ROM fragility to partitioning on OMAP3
is real enough.
On an IGEP0020 I was unable to create a bootable image -- one that would
boot x-loader so it would talk on the serial console -- even after a
couple of days struggling. It was only 'solved' in the end when Loic
imaged the start of his magic working card and I dd'd it on to mine.
Then it was happy even when I put my MLO on there.
