Hi Enric and Javier,
quoted
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?
That been said I think that is a good idea to have some default bootargs on the DT but since you can't append any boot option from U-Boot I would also add root=/dev/mmcblk0p2 rw rootwait so at least it will be able to mount the rootfs from the uSD/MMC.
True. Will re-send with those.
Also, many IGEP COM Module base boards also have serial consoles that are connected to the OMAP3 UART3 (ttyO2), so maybe is better to add this to omap3-igep.dtsi instead of omap3-igep0020.dts to avoid future duplication.
Ok.
Thanks and merry xmas,
Ezequiel
