Hi Sundeep,
This patchset is way cleaner!
I had a fast look and I like it, I'll try to make some time soon to
review details and test it.
Is your work interested on U-Boot or more focused in Linux kernel?
If you compile QEMU with libfdt support you can use the -dtb option to
pass the blob to the kernel directly, bypassing the bootloader.
If you need a bootloader you may give a look at coreboot which supports
dts well, see how Vladimir Serbinenko used Linux's dt to boot a QEMU
Versatile Express board:

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
