testing this set of patch on IFC6540, i noticed that not all
partitions from the eMMC are detected. booting [1] which is basically
3.17-rc7 with a few additional patches, i can see the following
relevant mmc traces:

[    1.162587] mmc0: BKOPS_EN bit is not set
[    1.315357] mmc0: new HS200 MMC card at address 0001
[    1.318098] mmcblk0: mmc0:0001 SEM16G 14.6 GiB
[    1.330377] mmcblk0boot0: mmc0:0001 SEM16G partition 1 4.00 MiB
[    1.333652] mmcblk0boot1: mmc0:0001 SEM16G partition 2 4.00 MiB
[    1.345424] mmcblk0rpmb: mmc0:0001 SEM16G partition 3 4.00 MiB
[    1.358135]  mmcblk0: p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 p11 p12 p13 p14 p15
[    1.365902]  mmcblk0boot1: p1
[    1.367833]  mmcblk0boot0: unknown partition table

on the same board, booting the board vendor kernel (which is based on
QCOM 3.10 tree), i can see much more partitions:

[    7.662379] mmc0: BKOPS_EN bit = 0
[    7.673036] mmc0: new HS200 MMC card at address 0001
[    7.673784] mmcblk0: mmc0:0001 SEM16G 14.6 GiB
[    7.674311] mmcblk0rpmb: mmc0:0001 SEM16G partition 3 4.00 MiB
[    7.677967]  mmcblk0: p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 p11 p12 p13
p14 p15 p16 p17 p18 p19 p20 p21 p22 p23 p24\
 p25

the complete dmesg log for can be found in our board lab, at [2]
