I'm pretty sure that git isn't that smart.  For example, between v2 and
v3 of the reorganization patches the ppc440 I2C driver moved from
cpu/ppc4xx/i2c.c to drivers/i2c/ppc4xx_i2c.c.  When I rebased the v2
patch on the latest U-Boot, git wasn't smart enough to know that
drivers/i2c/ppc4xx_i2c.c should be modified instead of cpu/ppc4xx/i2c.c
and I had to manually make the change.  I imagine the same thing will
happen to you unfortunately.

On the plus side, migrating your changes should be pretty easy.
Hopefully you can just update the paths in your patches to reflect the
new file locations, then re-apply them to a clean, up-to-date U-Boot
tree.  Something like the following may automate the process (untested):

perl -p -i -e 's/\-\-\- a\/cpu\/i386/\-\-\- a\/arch\/i386\/cpu/' *
perl -p -i -e 's/\+\+\+ b\/cpu\/i386/\+\+\+ b\/arch\/i386\/cpu/' *
perl -p -i -e 's/\-\-\- a\/lib_i386/\-\-\- a\/arch\/i386\/lib/' *
perl -p -i -e 's/\+\+\+ b\/lib_i386/\+\+\+ b\/arch\/i386\/lib/' *
perl -p -i -e 's/\-\-\- a\/lib_generic/\-\-\- a\/lib/' *
perl -p -i -e 's/\+\+\+ b\/lib_generic/\+\+\+ b\/lib/' *
...

Hopefully a few regular expressions can fix up most of the changes, but
I imagine there might be a few manual tweaks that need to be made too.

When you rebase your changes it would be nice if you mentioned how it
went and how you did it as I imagine others will have this same issue to
some degree.

Best,
Peter
