From cd3d48807dfb64f521fcbc30034d4e921d842a5b Mon Sep 17 00:00:00 2001 From: Tomas Melin Date: Fri, 25 Nov 2016 11:01:03 +0200 Subject: mmc: add bkops-enable command Add new command that provides possibility to enable the background operations handshake functionality (BKOPS_EN, EXT_CSD byte [163]) on eMMC devices. This is an optional feature of eMMCs, the setting is write-once. The command must be explicitly taken into use with CONFIG_CMD_BKOPS_ENABLE.
