From: "lin.gui" <lin.gui@xxxxxxxxxxxx> Detail: Add node "wp_grp_size", corresponding to WP_GRP_SIZE (write protect group size) of eMMC's CSD register. Scenario: The eMMC card can be set into write-protected mode to prevent data from being accidentally modified or deleted. Wp_grp_size (Write Protect Group Size) refers to an attribute of the eMMC card, used to manage write protection, and is the CSD register [36:32] of the eMMC device. Wp_grp_size (Write Protect Group Size) indicates how many eMMC blocks are contained in each write protection group on the eMMC card.
