Rearrange all voltage triplets for "opp_table0" to match the
specifications. "opp-microvolt" and "opp-microvolt-<name>" triplets
are in order of <target min max>, and NOT <min target max>.
Previously, the CPU would *always* spend its time at the "minimum"
voltage, ignoring the actual intended target. This is a regression
from previous behavior.
On an NBG6817 with a Qualcomm CPU of PVS bin #2...

- Exit early if a bad freq is detected. In the current state the freq

This adds support for the Askey RT4230W REV6
(Branded by Spectrum/Charter as RAC2V1K)
At this time, there's no way to reinstall the stock firmware so don't install
this on a router that's being rented.
Specifications:
Qualcomm IPQ8065
1 GB of RAM (DDR3)
512 MB Flash (NAND)
2x Wave 2 WiFi cards (QCA9984)
5x 10/100/1000 Mbps Ethernet (Switch: QCA8337)
1x LED (Controlled by a microcontroller that switches it between red and
blue with different patterns)
1x USB 3.0 Type-A
12V DC Power Input
UART header on PCB - pinout from top to bottom is RX, TX, GND, 5V
Port settings are 115200n8
More information: https://forum.openwrt.org/t/askey-rac2v1k-support/15830https://deviwiki.com/wiki/Askey_RAC2V1K
To check what revision your router is, restore one of these config backups
through the stock firmware to get ssh access then run
"cat /proc/device-tree/model".
https://forum.openwrt.org/t/askey-rac2v1k-support/15830/17
The revision number on the board doesn't seem to be very consistent so that's
why this is needed. You can also run printenv in the uboot console and if
machid is set to 177d, that means your router is rev6.
Note: Don't install this if the router is being rented from an ISP. The defined
partition layout is different from the OEM one and even if you changed the
layout to match, backing up and restoring the OEM firmware breaks /overlay so
nothing will save and the router will likely enter a bootloop.
How to install:
Method 1: Install without opening the case using SSH and tftp
You'll need:
RAC2V1K-SSH.zip:
https://github.com/lmore377/openwrt-rt4230w/blob/master/RAC2V1K-SSH.zip
initramfs and sysupgrade images
Connect to one of the router's LAN ports
Download the RAC2V1K-SSH.zip file and restore the config file that
corresponds to your router's firmware (If you're firmware is newer than what's
in the zip file, just restore the 1.1.16 file)
After a reboot, you should be able to ssh into the router with username:
"4230w" and password: "linuxbox" or "admin". Run the following commannds
fw_setenv ipaddr 10.42.0.10 #IP of router, can be anything as long as
it's in the same subnet as the server
fw_setenv serverip 10.42.0.1# #IP of tftp server that's set up in next
steps
fw_setenv bootdelay 8
fw_setenv bootcmd "tftpboot initramfs.bin; bootm; bootipq"
Don't reboot the router yet.
Install and set up a tftp server on your computer
Set a static ip on the ethernet interface of your computer (use this for
serverip in the above commands)
Rename the initramfs image to initramfs.bin, and host it with the tftp
server
Reboot the router. If you set up everything right, the router led should
switch over to a slow blue glow which means openwrt is booted. If for some
reason the file doesn't get loaded into ram properly, it should still boot to
the OEM firmware.
After openwrt boots, ssh into it and run these commands:
fw_setenv bootcmd "setenv mtdids nand0=nand0 && setenv mtdparts
mtdparts=nand0:0x1A000000@0x2400000(firmware) && ubi part firmware && ubi
read 0x44000000 kernel 0x6e0000 && bootm"
fw_setenv bootdelay 2
After openwrt boots up, figure out a way to get the sysupgrade file onto it
(scp, custom build with usb kernel module included, wget, etc.) then flash it
with sysupgrade. After it finishes flashing, it should reboot, the light should
start flashing blue, then when the light starts "breathing" blue that means
openwrt is booted.
Method 2: Install with serial access (Do this if something fails and you can't
boot after using method 1)
You'll need:
initramfs and sysupgrade images
Serial access:
https://openwrt.org/inbox/toh/askey/askey_rt4230w_rev6#opening_the_case
Install and set up a tftp server
Set a static ip on the ethernet interface of your computer
Download the initramfs image, rename it to initramfs.bin, and host it with
the tftp server
Connect the wan port of the router to your computer
Interrupt U-Boot and run these commands:
setenv serverip 10.42.0.1 (You can use whatever ip you set for the computer)
setenv ipaddr 10.42.0.10 (Can be any ip as long as it's in the same subnet)
setenv bootcmd "setenv mtdids nand0=nand0 &&
set mtdparts mtdparts=nand0:0x1A000000@0x2400000(firmware) && ubi part firmware
&& ubi read 0x44000000 kernel 0x6e0000 && bootm"
saveenv
tftpboot initramfs.bin
bootm
After openwrt boots up, figure out a way to get the sysupgrade file onto it
(scp, custom build with usb kernel module included, wget, etc.) then flash it
with sysupgrade. After it finishes flashing, it should reboot, the light should
start flashing blue, then when the light starts "breathing" blue that means
openwrt is booted.

With some talk with the ARM maintainer, it was notice that enlarging the limit
to the current value is VERY wrong and clash with other memory.
A better solution would be to reduce the IO space from 1MB to 64K as probably
it's a long lasting typo and even x86 arch doesn't have a IO space that big.
