Hi Fabio,

Attached are the two patch files that I applied in the 3.13 released
so that the kernel will detect my eMMC in DDR50.
(let me correct my previous email, I was mentioning SDR50 but it
should be DDR50).
eMMC info:

clock:          52000000 Hz
actual clock:   49500000 Hz
vdd:            21 (3.3 ~ 3.4 V)
bus mode:       2 (push-pull)
chip select:    0 (don't care)
power mode:     2 (on)
bus width:      3 (8 bits)
timing spec:    1 (mmc high-speed)
signal voltage: 0 (3.30 V)

I reboot my device often and it shows during the reboot.

Regards,

john
