Backport BLOCK OF support patch merged upstream and refresh pending BLOCK patches. This is a new way to declare partition table for BLOCK device (eMMC currently supported) with the use of DTS. Current pending patch are adapted to not cause regression with current downstream implementation of a similar functionality. Also enable the new OF_PARTITION config by default.

Subject: [PATCH 8/9] mmc: block: set fwnode of disk devices
|
|
|
|
Set fwnode of disk devices to 'block', 'boot0' and 'boot1' subnodes of
|
|
the mmc-card. This is done in preparation for having the eMMC act as
|
|
NVMEM provider.
