So it means that you probably need to report the problem to u-boot
upstream as a normal u-boot binary should discover the right boot
device without additional tweak.
Or do you have a link to the report ?

Thanks that didn't work but it turns out the new version of
u-boot doesn't
work correctly if the SRC_SBMR1 value is not set. The old version figured it

I modified u-boot to always boot from the MMC and now it works fine. Thanks
for your help.
