Patch applied, and now the eMMC is detected OK:

=> mmc info
Device: <NULL>
Manufacturer ID: 15
OEM: 100

Tran Speed: 52000000
Rd Block Len: 512
MMC version 5.0
High Capacity: Yes

Bus Width: 8-bit
Erase Group Size: 512 KiB
HC WP Group Size: 8 MiB
User Capacity: 29.1 GiB WRREL

RPMB Capacity: 4 MiB ENH

...  And I can load/boot the Kernel (as far as the /dev/mmc... prompt..)

Thanks!
