145b299139 hw/riscv: sifive_u: Add QSPI0 controller and connect a flash
This adds the QSPI0 controller to the SoC, and connects an ISSI
25WP256 flash to it. The generation of corresponding device tree
source fragment is also added.

Since the direct memory-mapped mode is not supported by the SiFive
SPI model, the <reg> property does not populate the second group
which represents the memory mapped address of the SPI flash.

With this commit, upstream U-Boot for the SiFive HiFive Unleashed
board can boot on QEMU 'sifive_u' out of the box. This allows users
to develop and test the recommended RISC-V boot flow with a real
world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to
L2LIM, then U-Boot SPL loads the payload from SPI flash that is
combined with OpenSBI fw_dynamic firmware and U-Boot proper.

Specify machine property `msel` to 6 to allow booting from the SPI
flash. U-Boot spl is directly loaded via `-bios`, and subsequent
payload is stored in the SPI flash image. Example command line:

$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -smp 5 -m 8G \
    -bios u-boot-spl.bin -drive file=spi-nor.img,if=mtd

898dc008e8 hw/riscv: microchip_pfsoc: Connect a Cadence SDHCI controller and an SD card
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

$ qemu-system-riscv64 -nographic -M microchip-icicle-kit -sd sdcard.img

56f6e31e7b hw/riscv: Initial support for Microchip PolarFire SoC Icicle Kit board
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.

riscv: sifive_u: Fix broken GEM support
At present the GEM support in sifive_u machine is seriously broken.
The GEM block register base was set to a weird number (0x100900FC),
which for no way could work with the cadence_gem model in QEMU.

Not like other GEM variants, the FU540-specific GEM has a management
block to control 10/100/1000Mbps link speed changes, that is mapped
to 0x100a0000. We can simply map it into MMIO space without special
handling using create_unimplemented_device().

Update the GEM node compatible string to use the official name used
by the upstream Linux kernel, and add the management block reg base
& size to the <reg> property encoding.

Tested with upstream U-Boot and Linux kernel MACB drivers.

ca9b7e29de kconfig: add CONFIG_MSI_NONBROKEN
Not all interrupt controllers have a working implementation of
message-signalled interrupts; in some cases, the guest may expect
MSI to work but it won't due to the buggy or lacking emulation.

In QEMU this is represented by the "msi_nonbroken" variable.  This
patch adds a new configuration symbol enabled whenever the binary
contains an interrupt controller that will set "msi_nonbroken".  We
can then use it to remove devices that cannot be possibly added
to the machine, because they require MSI.

82f5181777 kconfig: introduce kconfig files
The Kconfig files were generated mostly with this script:

  for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do
    set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
    shift
    if test $# = 1; then
      cat >> $(dirname $1)/Kconfig << EOF
config ${i#CONFIG_}
    bool

EOF
      git add $(dirname $1)/Kconfig
    else
      echo $i $*
    fi
  done
  sed -i '$d' hw/*/Kconfig
  for i in hw/*; do
    if test -d $i && ! test -f $i/Kconfig; then
      touch $i/Kconfig
      git add $i/Kconfig
    fi
  done

Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.
