This patch adds support for the MikroTik RouterBOARD RB493G, ported from the ar71xx target. See https://routerboard.com/RB493G for details Specification: - SoC Qualcomm Atheros AR7161 - RAM: 256 MiB - Storage: 128MiB NAND - Ethernet: 9x 1000/100/10 Mbps - USB 1x 2.0 / 1.0 type A - PCIe: 3x Mini slot - MicroSD slot Working: - Board/system detection - Ethernet - SPI - NAND - LEDs - USB - Sysupgrade Enabled (but untested due to lack of hardware): - PCIe - ath79_pci_irq struct has the slot/pin/IRQ mappings if needed Installation methods: - tftp boot initramfs image, scp then flash via "sysupgrade -n" - nand boot existing OpenWrt, scp then flash via "sysupgrade -n" Notes: - initramfs image will not work if uncompressed image size over ~8.5Mb - The "rb4xx" drivers have been enabled Signed-off-by: Christopher Hill <ch6574@gmail.com>
