Some MT7915 devices need to load the second part of the eeprom to
work properly. The mt76 driver is not yet ready to read the pre-cal
data via the NVMEM cell. Therefore, partially revert commit to fix
the device probe issue on some devices.
P.S.
Except for D-Link and Ubnt devices, It is still uncertain whether
pre-cal data is required for other devices in the patch.
This partially reverts commit 9ac891f8c4.

Installation
There are two known options:
1) The Luci-based UI.
2) Press and hold the reset button during power up.
The router will request 'recovery.bin' from a TFTP server at
192.168.1.88.
Both options require a signed firmware binary.
The openwrt image supplied by cudy is signed and can be used to
install unsigned images.
