[Qemu-devel] [Qemu devel v8 PATCH 0/5] 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

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.
@
https://github.com/Subbaraya-Sundeep/emcraft-uboot-sf2.git

Linux is 4.5 linux with Smartfusion2 SoC dts and clocksource
driver added by myself @
https://github.com/Subbaraya-Sundeep/linux.git

v8:
memory_region_init_ram to memory_region_init_rom in soc
%s/emcraft_sf2_init/emcraft_sf2_s2s010_init/g in som
Added mc->ignore_memory_transaction_failures = true in som
as per latest commit.
Code simplifications as suggested by Alistair in sysreg and ssi.

v7:
Removed vmstate_register_ram_global as per latest commit
Moved header files to C which are local to C source files
Removed abort() from msf2-sysreg.c
Added VMStateDescription in mss-timer.c

v6:
Moved some defines from header files to source files
Added properties m3clk, apb0div, apb0div1 properties
to soc.
Added properties apb0divisor, apb1divisor to sysreg
Update system_clock_source in msf2-soc.c
Changed machine name smartfusion2-som->emcraft-sf2

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
