mvebu: new subtarget cortex A53 This commit introduces new subtarget for Marvell EBU Armada Cortex A53 processor based devices. The first device is Globalscale ESPRESSObin. Some hardware specs: SoC: Marvell Armada 3700LP (88F3720) dual core ARM Cortex A53 processor up to 1.2GHz RAM: 512MB, 1GB or 2GB DDR3 Storage: SATA interface µSD card slot with footprint for an optional 4GB EMMC 4MB SPI NOR flash for bootloader Ethernet: Topaz Networking Switch (88E6341) with 3x GbE ports Connectors: USB 3.0 USB 2.0 µUSB port connected to PL2303SA (USB to serial bridge controller) for UART access Expansion: 2x 46-pin GPIO headers for accessories and shields with I2C, GPIOs, PWM, UART, SPI, MMC, etc MiniPCIe slot Misc: Reset button, JTAG interface Currently booting only from µSD card is supported. The boards depending on date of dispatch can come with various U-Boot versions. For the newest version 2017.03-armada-17.10 no manual intervention should be needed to boot OpenWrt image. For the older ones it's necessary to modify default U-Boot environment: 1. Interrupt boot process to run U-Boot command line, 2. Run following commands: (for version 2017.03-armada-17.06 and 2017.03-armada-17.08) setenv bootcmd "load mmc 0:1 0x4d00000 boot.scr; source 0x4d00000" saveenv (for version 2015.01-armada-17.02 and 2015.01-armada-17.04) setenv bootargs "console=ttyMV0,115200 root=/dev/mmcblk0p2 rw rootwait" setenv bootcmd "ext4load mmc 0:1 ${fdt_addr} armada-3720-espressobin.dtb; ext4load mmc 0:1 ${kernel_addr} Image; booti ${kernel_addr} - ${fdt_addr}" saveenv 3. Poweroff, insert SD card with OpenWrt image, boot and enjoy. Signed-off-by: Tomasz Maciej Nowak <tomek_n@o2.pl>
