The Hardware is a ZYXEL NSA310S.
The NS310S is a DB-88F6702A-BPE board, also known as DB6702A-GMtech.
Like in DLINK DNS-320 (B2) or LaCie CloudBox.

The SOC is a Marvell 88F6282 (ARMADA 300).
The Armada 300 is in the KIRKWOOD family.
The 88F6282 is not upstream.

The GPL code from Zyxel is based on Marvell 3.6.0.
The Marvell u-boot are based on the U-Boot 1.1.4.

My study references are shared on a wiki[1]
