[PATCH v2 3/3] arm: mvebu: Initial ESPRESSOBin-Ultra board support
Luka Kovacic
luka.kovacic at sartura.hr
Mon Feb 15 20:59:34 CET 2021
Add initial support for the ESPRESSOBin-Ultra board from Globalscale
Technologies, Inc.
The board is based on the 64-bit dual-core Marvell Armada 3720 SoC.
Peripherals:
- 5 Gigabit Ethernet ports (WAN has PoE, up to 30W, Topaz 6341 switch)
- RTC clock (PCF8563)
- USB 3.0 port
- USB 2.0 port
- 4x LED
- UART over Micro-USB
- M.2 slot (2280)
- Mini PCI-E slot
Additionally, automatic import of the Marvell hw_info parameters is
enabled via the recently added hw_info command.
The parameters stored in Marvell hw_info are usually the board serial
number and MAC addresses.
