[Qemu-arm] [Qemu-devel RFC v2 0/4] Add support for Smartfusion2 SoC

[Subbaraya Sundeep]

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

U-boot is from Emcraft with modified SPI driver not to use PDMA.
Linux is 4.5 linux with Smartfusion2 SoC dts and clocksource 
driver added by myself @
https://github.com/Subbaraya-Sundeep/linux.git

Baremetal elfs from Microsemi Softconsole IDE are also working.

Changes from v1:
    Added SPI controller.

Thanks,
Sundeep
