Hi Qemu-devel,

I am trying to add Smartfusion2 SoC.
SoC is from Microsemi and System on Module(SOM)
board is from Emcraft systems. Smartfusion2 has hardened
Microcontroller(Cortex-M3)based Sub System and FPGA fabric.
At the moment only system timer, sysreg and SPI
controller are modelled.

Testing:
./arm-softmmu/qemu-system-arm -M smartfusion2-som -serial mon:stdio \
-kernel u-boot.bin -display none -drive file=spi.bin,if=mtd,format=raw

Binaries u-boot.bin and spi.bin are at:
https://github.com/Subbaraya-Sundeep/qemu-test-binaries.git

U-boot is from Emcraft with modified
    - SPI driver not to use PDMA.
    - ugly hack to pass dtb to kernel in r1.

Linux is 4.5 linux with Smartfusion2 SoC dts and clocksource
driver added by myself @

v5
    As per Philippe comments:
        Added abort in Sysreg if guest tries to remap memory
        other than default mapping.
        Use of CONFIG_MSF2 in Makefile for soc.c
        Fixed incorrect logic in timer model.
        Renamed msf2-timer.c -> mss-timer.c
                msf2-spi.c -> mss-spi.c also type names
        Renamed function msf2_init->emcraft_sf2_init in msf2-som.c
        Added part-name,eNVM-size,eSRAM-size,pclk0 and pclk1
            properties to soc.
        Pass soc part-name,memory size and clock rate properties from som.
v4:
    Fixed build failure by using PRIx macros.
v3:
    Added SoC file and board file as per Alistair comments.
v2:
    Added SPI controller so that u-boot loads kernel from spi flash.
v1:
    Initial patch set with timer and sysreg

Thanks,
Sundeep
