Hello. I read the posts a couple days ago about the Python issues with Kconfig feature. I didn't see a resolution on how this would be fixed. I am running Ubuntu 14.04LTS, building u-boot and the problem I have is that the eldk tools have a older python (2.7.3) which does not have the subprocess module but the current Ubuntu python (2.7.6) does include the subprocess module. When I add the eldk (cross compiler) path before my env $PATH the defconfig fails in multiconfig.py (uses the python in the eldk toolkit). Can I just remove python from the eldk tools (so the newer python will be used) or is that older python version required for some other script in the cross compiler?

You only need /opt/eldk-5.5/armv5te/sysroots/i686-eldk-linux/usr/bin/armv5te-linux-gnueabi to be added to your PATH to compile U-Boot (or the kernel). I don't know why OpenEmbedded-based SDKs default to such a stripped down Python2 installation.
Because it is unneeded bloat? Adding a DEPENDS to the U-boot recipe for python-subprocess and python-xyz and rebuilding the sdk should fix this I guess.
Putting on my OE-guy hat, if we're shipping a host python for some good reason, it should be as useful as a stock python install on desktop-or-server-distro-du-jour. I did some quick poking when I first hit this and it seems the OE one ships with almost nothing for external modules which made me question why it's even shipped.
