The OpenMesh A62 is a tri-band device (1x 2.4GHz, 2x 5GHz) with special
filters in front of the RX+TX paths to the 5GHz PHYs. These filtered
channel can in theory still be used by the hardware but the signal strength
is reduced so much that it makes no sense.

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the factory image to the u-boot when the device boots up.
The initramfs image can be started using
setenv bootargs 'loglevel=8 earlycon=msm_serial_dm,0x78af000 console=ttyMSM0,115200 mtdparts=spi0.0:256k(0:SBL1),128k(0:MIBIB),384k(0:QSEE),64k(0:CDT),64k(0:DDRPARAMS),64k(0:APPSBLENV),512k(0:APPSBL),64k(0:ART),64k(0:custom),64k(0:KEYS),15552k(inactive),15552k(inactive2)'
