Add support for the Artesyn MVME7100 Single Board Computer.
The MVME7100 is a 6U form factor VME64 computer with:
- A two e600 cores Freescale MPC8641D CPU
- 2 GB of DDR2 onboard memory
- Four Gigabit Ethernets
- Five 16550 compatible UARTs
- One USB 2.0 port
- Two PCI/PCI eXpress Mezzanine Card (PMC/XMC) Slots
- A DS1375 Real Time Clock (RTC)
- 512 KB of Non-Volatile Memory (NVRAM)
- Two 64 KB EEPROMs
- 128 MB NOR and 4/8 GB NAND Flash
This patch is based on linux-4.7-rc1 and has been only boot tested.
Limitations:
This patch covers only models 171 and 173
No plans to support CPLD timers
Know issues:
All four PHYs work in polling mode
Configuration is missing for:
PCI IDSEL and PCI Interrupt definition
Support is missing for:
Cache and memory controllers (which are very similar to the 85xx ones
but right now I don't know if we can re-use their support)
Watchdog, USB, NVRAM, NOR, NAND, EEPROMs, VME, PMC/XMC and RTC
