From: Konstantin Porotchkin kostap@marvell.com
Align the Armada-8040-db and Armada-7040-db SPI and I2C DTS settings with latest DB settings: - 8040-db: disable i2c0 and spi0 on AP (MPPs are reserved for SDIO) - 8040-db: disable cps_i2c0 on CP1 - 8040-db: enable spi1 on CP1 (the new location of the boot flash) The spi1 on CP1 is aliased as spi0 since this is the way the driver enumerates it.
Changes for v2: - 7040-db: remove i2c0 and spi0 entries from AP (MPPs are reserved for SDIO)
