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

So far, specifying "BOARD_NAME := routerboard" is required by the
upgrade code of Mikrotik NAND devices, as "sysupgrade-routerboard"
is hardcoded in platform_do_upgrade_mikrotik_nand().
This patch replaces the latter with a grep for the name like it
is already done in nand_upgrade_tar() in /lib/upgrade/nand.sh.
By that, BOARD_NAME is obsolete now for this device.

This commit creates the ath79/mikrotik subtarget in order to support
MikroTik devices based on Qualcomm Atheros MIPS SoCs.
MikroTik devices need a couple of specific features: the split MiNOR
firmware MTD format, which is not used by other devices, and the 4k
sector erase size on SPI NOR storage, which can not be added to the
ath79/generic and ath79/nand subtargets now.
Additionally, the commit moves the two MikroTik devices already in
the generic and nand subtargets to this new one.
Tested on the RB922 board and the wAP AC router.
