Microchip PolarFire SoC integrates 3 GPIOs controllers. It seems
enough to create unimplemented devices to cover their register
spaces at this point.
With this commit, QEMU can boot to U-Boot (2nd stage bootloader)
all the way to the Linux shell login prompt, with a modified HSS
(1st stage bootloader).
For detailed instructions on how to create images for the Icicle
Kit board, please check QEMU RISC-V WiKi page at:

Microchip PolarFire SoC integrates 2 Candence GEMs to provide
IEEE 802.3 standard-compliant 10/100/1000 Mbps ethernet interface.
On the Icicle Kit board, GEM0 connects to a PHY at address 8 while
GEM1 connects to a PHY at address 9.
The 2nd stage bootloader (U-Boot) is using GEM1 by default, so we
must specify 2 '-nic' options from the command line in order to get
a working ethernet.

On the Icicle Kit board, the HSS firmware utilizes the on-chip DMA
controller to move the 2nd stage bootloader in the system memory.
Let's connect a DMA controller to Microchip PolarFire SoC.

Microchip PolarFire SoC integrates one Cadence SDHCI controller.
On the Icicle Kit board, one eMMC chip and an external SD card
connect to this controller depending on different configuration.
As QEMU does not support eMMC yet, we just emulate the SD card
configuration. To test this, the Hart Software Services (HSS)
should choose the SD card configuration:
$ cp boards/icicle-kit-es/def_config.sdcard .config
$ make BOARD=icicle-kit-es
The SD card image can be built from the Yocto BSP at:
https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp
Note the generated SD card image should be resized before use:
$ qemu-img resize /path/to/sdcard.img 4G
Launch QEMU with the following command:
$ qemu-system-riscv64 -nographic -M microchip-icicle-kit -sd sdcard.img

Microchip PolarFire SoC has 5 MMUARTs, and the Icicle Kit board
wires 4 of them out. Let's connect all 5 MMUARTs.

This is an initial support for Microchip PolarFire SoC Icicle Kit.
The Icicle Kit board integrates a PolarFire SoC, with one SiFive's
E51 plus four U54 cores and many on-chip peripherals and an FPGA.
For more details about Microchip PolarFire Soc, please see:
https://www.microsemi.com/product-directory/soc-fpgas/5498-polarfire-soc-fpga
Unlike SiFive FU540, the RISC-V core resect vector is at 0x20220000.
The following perepherals are created as an unimplemented device:
- Bus Error Uint 0/1/2/3/4
- L2 cache controller
- SYSREG
- MPUCFG
- IOSCBCFG
More devices will be added later.
The BIOS image used by this machine is hss.bin, aka Hart Software
Services, which can be built from:
https://github.com/polarfire-soc/hart-software-services
To launch this machine:
$ qemu-system-riscv64 -nographic -M microchip-icicle-kit
The memory is set to 1 GiB by default to match the hardware.
A sanity check on ram size is performed in the machine init routine
to prompt user to increase the RAM size to > 1 GiB when less than
1 GiB ram is detected.
