Hmm, adding this option fixed the MMC problem. I mean, I can see the MMC
booting vexpress-a15. vexpress-a9 still doesnt shows up. I have tried
several kernels/configs combinations.
v3.9 - vexpress_defconfig + VEXPRESS
v3.9 - with configs from linaro sources as in this tutorial (
https://wiki.linaro.org/Resources/HowTo/KernelDeploy)
v3.9 - with a config from (3.2.0-1800-linaro-lt-vexpress-a9) that I can
sucessfully boot
Can you guys suggest any other config I could try? Or kernel version or
repo?
Kind Regards,
Erlon
