I'm trying to compile u-boot with buildroot, but it fails with:

                /usr/bin/make -j1 -C 
/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2 
\
                ""_config
make[1]: Entering directory 
`/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2'
make[1]: *** No rule to make target `_config'.  Stop.
make[1]: Leaving directory 
`/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2'
make: *** 
[/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2/.configured] 
Error 2

Apparently it expects a BOARD_NAME variable, but I don't know what to put in 
it (I looked at the makefile and can't find the ml405 referenced in there).

I think you need to figure out how to build u-boot for your board
outside buildroot, before you try to build it inside buildroot.

Working on it...

While I do that, I have a side question:
is it possible to boot off a first kernel on a local partition, but tell it 
to tftp boot off another kernel instead ?

The rational is that I have a working system on a card in my embedded 
system, but if possible I'd like to have it boot off the latest version 
available on the network.

And if not available, simple boot using fallback parameters.

Makes sense ?
