Since udev-182, udev no longer creates device nodes under /dev
and this has to be managed by the kernel devtmpfs filesystem.
This means that a kernel built with the current OMAP2+ config
will not boot on a system with a recent udev.
Also, it is good to have /dev automatically mounted since some
non-initramfs based setups assumes this and don't manually mount it.

Whoever is taking the patch can _probably_ fix it up while applying.

For curiosity sake, any examples of such setups? I am using fedora 17 on
DaVinci and that doesn't seem to need it. Anyway, agreed that its better
to keep it enabled.
Thanks,

Hi Sekhar,
Thanks for clarifying this, I read that it was udev-182 from the Linux from
scratch documentation:

I'm using an IGEPv2 (TI OMAP3 DM3735) with an openembedded build and the oe udev
init script from the recipe I use seems to assume this.

Hi Tony,
I resend a v2 today: [PATCH v2 1/1] ARM: OMAP2+: omap2plus_defconfig:
enable devtmpfs and automount
That fixes an issue in the patch comments. Sekar Nori pointed out that
the first udev to make this a requirement was 176 not 182.
So probably is better if you can apply that one instead.
Thanks a lot and best regards,
Javier
