[U-Boot-Users] [PATCH 3/3] ppc4xx: Add initial esd PMC440 board support

[Matthias Fuchs]

Hi Wolfgang, Hi Stefan,

thanks for your comments. I tried to consider them in my updated patch 
series. As a consequence of the lists size limit (40k) and our little 
discussion on irc I banned cogito from my system an started with plain 
git which seems to be slightly more powerful:-)

To fool the list's size limit I did two things: first I split the huge patch (3/3)
into three single patches. Even they do not really make sense without
the others, they will not break U-Boot's buildsystem at any time.

The second very cool thing is the very powerful git option for creating 
patch that contain 1:1 copies of existing files. The PMC440 board 
uses sequoia's sdram.c and sdram.h. Together these two files would
explode the 40k size limit. So it's a good idea to generate patch by calling:

	format-patch -5 -C -C -n

or (which has the same effect):

	format-patch -5 -C --find-copies-harder -n

This is how the patch summary looks like in this case:

board/{amcc/sequoia => esd/pmc440}/Makefile        |    4 +-
 board/{amcc/sequoia => esd/pmc440}/config.mk       |    0
 board/{amcc/sequoia => esd/pmc440}/init.S          |   16 +-

Please notice that the following fife patches replace all of my previous three 
patches. They are generated against Stefan's ppc4xx/for-1.3.1 brach because
of the 4xx DCACHE rework.
