What is this extlinux.conf file for? As far as I can see, this defconfig
does not use syslinux, which is anyway only available on x86 and x86_64.

Would it not be better to backport upstream commit 0171b07373cc (ARM:
dts: stm32: fix stm32mp157c-odyssey card detect pin):

    -       cd-gpios = <&gpiob 7 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
    +       cd-gpios = <&gpioi 3 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;

Except for those two minor nits, this v2 looks OK.

Yann E. MORIN.

Breaking News! U-Boot can read the extlinux.conf format! More at 10!

I was not aware of that, so disregard this comment of mione, sorry.
