where is defined the mmcblk

Hello,

Where is defined the mmcblk?

When my kernel starts I have these mmcblk:

mmc2: new DDR MMC card at address 0001
mmcblk2: mmc2:0001 Q2J54A 3.58 GiB
mmcblk2boot0: mmc2:0001 Q2J54A partition 1 16.0 MiB
mmcblk2boot1: mmc2:0001 Q2J54A partition 2 16.0 MiB
mmcblk2rpmb: mmc2:0001 Q2J54A partition 3 512 KiB

So, I would like change or redefine these bloks.

Thanks,

one can refer to the steps of chapter 4.3.3 Partitioning the SD/MMC card of enclosed file, then partition your sd card.
