Agreed, let's update that.

Hey the good news is that you've updated your build system to support
also appended dtb images, thanks for doing that!

Looks like you need some things updated and added to your .config.

-# CONFIG_OMAP_MUX is not set
+CONFIG_MACH_OMAP_GENERIC=y

That we should nowadays always select though.

CONFIG_REGULATOR_FIXED_VOLTAGE=y

This you will need for Ethernet.

CONFIG_PINCTRL_SINGLE=y

This is good to have, will be needed especially for for UART
wake-up events with deeper idle modes enabled once the pending
pinctrl patches are merged.

Also, can you please add these for NFSroot:

CONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=y
CONFIG_ROOT_NFS=y

That way I can also boot test your .config on regular basis ;)

Then there's a pending patch to change drivers/i2c/busses/i2c-omap.c
to use just a regular module_init, that should remove the i2c timeout
errors as then deferred probe will work properly.

BTW, maybe add a link to your build system to www.arm.linux.org.uk
developer page too? At least I could not find a link to it.

Regards,

Tony
