Devices with PCIe-Switches like the WNDR4700, MR24 and WNDAP660
need to have the interrupts property specified in the device-tree
for the legacy pci interrupt signaling method to work.
If the proper interrupt value is not specified, the default INTA
IRQ 12 is taken for all devices. This is especially bad, if the
device is setup to use INTC, because these interrupts will not
be serviced.
Russell Senior reported his experience on the MR24:
"The symptom is client devices can't see the beacons.
Wifi ifaces appear, can scan and hear other networks,
but clients can't see the MR24's SSIDs."
(The interrupts-property on the WNDAP620 was optional since it
uses INTA by default. Likewise the MX60W is in the same category)

This patch adds support for the Netgear WNDAP620 and WNDAP660,
they are similar devices, but due to the LAN LED configuration,
the switch setup and WIFI configuration each gets a different
device target.

Flashing requirements:
- needs a tftp server at 192.168.1.10/serverip.
- special 8P8C(aka RJ45)<->D-SUB9 Console Cable
("Cisco Console Cable"). Note: Both WNDAP6x0 have
a MAX3232 transceivers, hence no need for any separate
CMOS/TTL level shifters.
External Antenna:
The antennae mux is controlled by GPIO 11 and GPIO14. Valid Configurations:
= Config# = | = GPIO 11 = | = GPIO 14 = | ===== Description =====
1. | 1 / High | 0 / Low | Use the internal antennae (default)
2. | 0 / Low | 1 / High | Use the external antennae
The external antennaes are only meant for the 2.4 GHz band.
One-way Flashing instructions via u-boot:
0. connect the serial cable to the RJ45 Console Port
Note: This requires a poper RS232 and not a TTL/USB adaptor.
1. power up the AP and interrupt the u-boot process at
'Hit any key to stop autoboot'
2. setup serverip and ipaddr env settings
Enter the following commands into the u-boot shell
# setenv ipaddr 192.168.1.1
# setenv serverip 192.168.1.10
3. download the factory.img image to the AP
Enter the following commands into the u-boot shell
# tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-squashfs-factory.img
4. verfiy image integrity
Enter the following commands into the u-boot shell
# crc32 $fileaddr $filesize
If the calculated crc32 checksum does not match, go back to step 3.
5. flash the image
Enter the following commands into the u-boot shell
# nand erase 0x110000 0x1bd0000
# nand write ${kernel_addr_r} 0x110000 ${filesize}
6. setup uboot environment
Enter the following commands into the u-boot shell
# setenv bootargs
# setenv fileaddr
# setenv filesize
# setenv addroot 'setenv bootargs ${bootargs} root=/dev/ubiblock0_0'
# setenv owrt_boot 'nboot ${kernel_addr_r} nand0 0x110000; run addroot; run addtty; bootm ${kernel_addr_r}'
# setenv bootcmd 'run owrt_boot'
# saveenv
7. boot
# run bootcmd
Booting initramfs instructions via u-boot:
Follow steps 0 - 2 from above.
3. boot initramfs
Enter the following commands into the u-boot shell
# tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-initramfs-kernel.bin
# run addtty
# bootm ${kernel_addr_r}
