[U-Boot] [PATCH] arm: baltos: move the board to CONFIG_BLK

yegorslists at googlemail.com yegorslists at googlemail.com
Tue Nov 20 14:45:04 UTC 2018


From: Yegor Yefremov <yegorslists at googlemail.com>

Use DM for both MMC and USB subsystems and use dedicated DTS
for U-Boot configuration.

Disable SPL support for GPIO and remove EVMSK leftover for
DDR power control via GPIO.
