[U-Boot-Users] lubbock patch: ram, flash, ethernet

[David Brownell]

U-Boot support for Lubbock still needs some work, but this fixes
a few of the more blatant problems.  I look forward to replacing
that crufty old "BLOB" with a shiny new U-Boot.  :)

I saw some email archived from about 10 months back saying that
the TFTP timeout/retry problems went away given PXA timer updates,
but like the ethernet patch that was also needed, a patch wasn't
posted or merged.  Maybe someone who has unmerged PXA updates has
the relevant code ready to merge?

There's a gumstix patch against 1.1.2 which fixes the timer problems  
which lead to TFTP timeouts on PXA.

http://localhost/svn/gumstix-buildroot/trunk/sources/u-boot- 
get_timer.patch

I haven't submitted the patch yet, because I have a handful of others  
too which need to be cleaned of stuff which doesn't want to be in the  
mainline before I submit them.

That one though, is pretty clean and nicely separate from anything that  
doesn't apply to all PXA platforms.

Which, to save anyone else tracking down the Gumstix subversion
info, I've attached.  Adding this over my patch (and a few other
tweaks, only one of which might be important) gives me a U-Boot
that can download a kernel starting from DHCP!  Worth merging.

Thanks, Craig.  :)

p.s. Those MMC patches looked rather interesting too.  A fully
     featured Lubbock U-Boot would talk Ethernet, MMC, and CF;
     we're not there yet, but given Ethernet I'd call it very
     much usable.

The MMC patches are part of what's not really complete there at the 
moment.  There's some SD support I want to fold back in, and some ugly 
debugging stuff which needs to be cleaned up.

If anyone is curious in the meantime, feel free to browse/take from

http://svn.rungie.com/svn/gumstix-buildroot/trunk/sources/

The u-boot* files are the ones of interest here.

Added, thanks. But please provide a proper CHANGELOG entry next time.
