defconfig for panda

defconfig for panda

[Kumar Gala]

As I'm new to the OMAP community this might be a stupid question but trying to just build and run a stock v3.3 kernel on a pandaboard.  In doing so it seems as if some basic drivers are not enabled in omap2plus_defconfig for the board.  I'm trying to figure out if this is normal for some reason or just an oversight.

For example, USB and USB ethernet (SMC95xx).  I notice the linaro kernel tree introduces an omap4_defconfig, so just wondering should I send patches to omap2plus_defconfig or what?

thanks

We can add those to omap2plus_defconfig for sure, but let's have
them added as modules. Then distros can use that easily in a
standard way using initramfs-tools etc.

Let's not change the drivers that are currently built in if they're
needed for mounting mmc or nfsroot. Those can be changed later on.

Tony

I'll work up a patch, however I was doing this as I was trying to get NFS root working and thus would need USB + USB ethernet compiled in and not as modules for panda.  Is that ok?

Maybe, let's take a look how much bigger the kernel becomes.
Also we need to check if the same EHCI configuration works
for omap3/4.

FWIW, the same EHCI + SMSC95xx config is used for Beagle xM for
nfsroot. First thing I enable on any builds.

OK, can somebody please do a minimal patch to omap2plus_defconfig
for this?

Basically run make savedefconfig with those changes added and
then diff against omap2plus_defconfig.

I have not seen the patch to enable this on the list,
so here is the patch[1] to do the same.
