[Buildroot] Fwd: Re: [git commit] boot/at91bootstrap3: migrate to pkg-kconfig

[Patrick Noffke]

Sorry, didn't send to the list.

My problem may be because I patched at91bootstrap3, and I probably missed 
something there.  I was changing some of its configuration to enable SDRAM and 
NOR flash for this board.

This is my problem.  I didn't know about oldconfig -- I thought defconfig was 
getting run.

make oldconfig is replacing some of my settings for the at91bootstrap3 package.  

In particular, in my custom config, I have 

#CONFIG_MACH_TYPE="1830"
CONFIG_MACH_TYPE="0xFFFFFFFF"
CONFIG_SDRAM=y

and these are getting replaced with

CONFIG_MACH_TYPE="1830"
# CONFIG_SDRAM is not set

Should oldconfig be doing this?

When I checkout this revision, the package builds fine.

Thanks,
