[PATCH v3 2/2] arm: octeontx2: Add Octeon TX2 CN913x DB support

[Stefan Roese]

From: Konstantin Porotchkin <kostap at marvell.com>

This patch adds the base support for the Marvell Octeon TX2 CN913x DB.
Only one defconfig is added with this patch. Other board variants are
available (NAND, MMC booting) and images for these boards can be
generated by following the documentation added in the included README.

+Not all board variants are represented with a specific defconfig in
+mainline U-Boot. Here a small documentation on how to generate U-Boot
+images for all other board variants, available via different dts
+files and defconfigs.
+
+Use a different dts than in the defconfig:
+
+make DEVICE_TREE=cn9131-db-B
+
+Use a different boot device (e.g. MMC or NAND instead of SPI NOR):
+
+For MMC, please make the following changes to the defconfig via
+e.g. "make menuconfig":
+Remove CONFIG_MVEBU_SPI_BOOT
+Select CONFIG_MVEBU_MMC_BOOT
+Remove CONFIG_ENV_IS_IN_SPI_FLASH
+Select CONFIG_ENV_IS_IN_MMC
+
+For NAND, please make the following changes to the defconfig via
+e.g. "make menuconfig":
+Remove CONFIG_MVEBU_SPI_BOOT
+Select CONFIG_MVEBU_NAND_BOOT
+Remove CONFIG_ENV_IS_IN_SPI_FLASH
+Select CONFIG_ENV_IS_IN_NAND
