[PATCH v2 0/3] Add (more) missing PolarFire SoC io regions

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

Hey all,
But of a v2 of what I sent the other day [0]..
Apart from DDR (see [1]), these should be the last bits needed to get
recent Linux kernels booting again for Icicle/PolarFire SoC. Previously,
I had been disabling the hwrng and PCI but I keep forgetting that is
required and decided to fix that.

I'm not entirely sure if I have done some sort of no-no thing by
registering the same interrupt with both the IOSCB and SYSREG regions.
The interrupt is raised after the system controller handles a service
via the mailbox. The mailbox's status, control and mailbox registers
are all part of the IOSCB region. It's cleared by a write to a register
in the SYSREG region.
Since my goal here is to add the regions/peripherals without actually
implementing them so that Linux etc, I'm just raising an interrupt
once a guest requests a service & reporting a status indicating that the
service request failed.

Thanks,
Conor.
