Load addresses:
* stock
* 0x80010000: FIT image
* 0x81001000: kernel image -> entry
* OpenWrt
* 0x80010000: FIT image
* 0x82000000: uncompressed kernel+relocate image
* 0x80001000: relocated kernel image -> entry
Notes:
* This device has a dual-boot partition scheme, but this firmware works
only on boot partition 1. The stock web interface will flash only on the
inactive boot partition, but the recovery web page will always flash on
boot partition 1.
Installation via recovery mode:
1. Press reset button, power up the device, wait >10s for CPU LED
to stop blinking.
2. Upload recovery image through the recovery web page at 192.168.0.1.
Revert to stock firmware:
1. Install stock image via recovery mode.

Commit f4a79148f8 ("ramips: add support for ipTIME AX2004M") seems to
leak KERNEL_LOADADDR 0x82000000 to other devices, causing the to no
longer boot. The leak is visible in u-boot:
Using 'config-1' configuration
Trying 'kernel-1' kernel subimage
Description: MIPS OpenWrt Linux-5.10.92
Type: Kernel Image
Compression: lzma compressed
Data Start: 0x840000e4
Data Size: 10750165 Bytes = 10.3 MiB
Architecture: MIPS
OS: Linux
Load Address: 0x82000000
Entry Point: 0x82000000
Normally, it should look like this:
