Subject: [PATCH] arm64: dts: marvell: armada-37xx: Enable emmc on espressobin
|
|
|
|
|
|
|
|
|
|
The ESPRESSObin board has a emmc interface available on U11: declare it
|
|
|
|
|
and let the bootloader enable it if the emmc is present.
|
|
|
|
|
|
|
|
|
|
[gregory.clement@bootlin.com: disable the emmc by default]
