Hi Enric and Javier,

The u-boot 'bootargs' env overwrites the one from chosen ?

I just tested and U-Boot 'bootargs' has precedence over DT bootargs
but I didn't find a way to append boot parameters from U-Boot. You can
either overwrite it completely or not.

Yes. That seems to be the current case.
Perhaps we can merge
ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER
and CMDLINE_EXTEND in one generic config stating
the desired bootargs behavior.

Does this sound sane?

Hi Ezequiel,

You could enable ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER on
omap2plus_defconfig

Actually, ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER depends
on ARM_ATAG_DTB_COMPAT being selected and it's only compatibility
stuff for bootloaders non DTB capable.

I don't think we should add that to omap2plus_defconfig.

but just having a sane DTB bootargs default value
is better IMHO.

Agreed. I'll send a v2 with your proposed default command line.
