Both builds provide close to 100% hardware support, some slight differences are listed below.

Mainline kernel with large hardware support, headers and some firmware included
Docker ready
Both mPCIe are operational and convertible to mSATA, M2 operational
Added patch to unlock Atheros regulatory restrictions which unlock 5Ghz AP mode in cheap Atheros cards (ath9 driver)
Bluetooth ready (working with supported external keys)
I2C ready. Basic i2c tools included.
SPI ready but untested.
SFP is working at up to 1GB/s even with faster fiber modules
SFP DDMI is operational (sudo ethtool -m eth2)

all builds suffer from minor problems with specific mPCIe combinations. If you run into problems check this test matrix for some known working/not working combinations.

To convert mPCIe to mSATA you have to enable the corresponding patches in u-boot-mvebu. Afterwards rebuild u-boot with our build system and write the new u-boot to your boot medium. If you need assistance ask in the forum.

In case you ever run into troubles and ask for help in the forums please ensure to provide a serial console log (UART adapter on board accessible through Micro USB with 115200/8/N/1 settings)
The boards can boot from various sources that are adjustable with a DIP switch. Comprehensive information about the necessary preparations available here.
