From 4db944ab44a7bc8b495eece6afb124c632b02ef5 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Thu, 11 Apr 2019 22:22:53 +1200 Subject: arm: mvebu: Add DB-XC3-24G4XG board The DB-XC3-24G4XG is a switch development board from Marvell. It can either use and external CPU card such as the db-88f6820-amc or the internal CPU that is integrated into the switch. Add support for running U-Boot on the internal CPU and enable the USB, SPI and NAND peripherals. For now this needs the bin_hdr from the Marvell U-Boot for this board.
