This board has been supported in the ar71xx.

This also supports the 5GHz flavour of the board.
Hardware:
* SoC: Atheros AR9342,
* RAM: DDR 64MB,
* SPI NOR: 64KB,
* NAND: 128MB,
* Ethernet: x1 10/100/1000 port with passive POE in,
* Wi-Fi: 802.11 b/g/n,
* PCIe,
* USB: 2.0 EHCI controller, connected to mPCIe slot and a Type-A
port -- both can be used for LTE modem, but only one can be
used at any time.
* LEDs: 5 general purpose LEDs (led1..led5), power LED, user LED,
Ethernet phy LED,
* Button,
* Beeper.
Not working:
* Button: it shares gpio line 15 with NAND ALE and NAND IO7,
and current drivers doesn't easily support this configuration,
* Beeper: it is connected to bit 5 of a serial shift register
(tested with sysfs led trigger timer). But kmod-gpio-beeper
doesn't work -- we left this as is for now.
Flashing:
* Use the RouterBOARD Reset button to enable TFTP netboot,
boot kernel and initramfs and then perform sysupgrade.
* From ar71xx OpenWrt firmware run:
$ sysupgrade -F /tmp/<sysupgrade.bin>

(cherry picked from commit 695a1cd53c)
On Mikrotik SPI NOR devices, the firmware partition must be erased when
flashing from stock firmware, otherwise leftover bits (in particular a
kernel signature) can trigger a boot loop.
When booted from initramfs (the only way to install OpenWRT on these
devices), this patch unconditionally erases the firmware partition in
the do_upgrade() stage for all supported SPI NOR devices.

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
