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 emcraft-sf2 -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 v10: Added msf2_sysreg_realize in msf2-sysreg.c modified unimplemented devices names: pdma->dma and hpdma->hs-dma used uint8_t for apb divisors properties simplified msf2_divbits() using ctz32() v9: used trace instead of DB_PRINT in msf2-sysreg.c used LOG_UNIMP for non guest errors in msf2-sysreg.c added unimplemented devices in msf2-soc.c removed .alias suffix in alias memory region name for eNVM removed mc->ignore_memory_transaction_failures in msf2-som.c 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 Subbaraya Sundeep (5): msf2: Add Smartfusion2 System timer msf2: Microsemi Smartfusion2 System Register block msf2: Add Smartfusion2 SPI controller msf2: Add Smartfusion2 SoC msf2: Add Emcraft's Smartfusion2 SOM kit default-configs/arm-softmmu.mak | 1 + hw/arm/Makefile.objs | 1 + hw/arm/msf2-soc.c | 232 +++++++++++++++++++++++ hw/arm/msf2-som.c | 94 ++++++++++ hw/misc/Makefile.objs | 1 + hw/misc/msf2-sysreg.c | 160 ++++++++++++++++ hw/misc/trace-events | 5 + hw/ssi/Makefile.objs | 1 + hw/ssi/mss-spi.c | 404 ++++++++++++++++++++++++++++++++++++++++ hw/timer/Makefile.objs | 1 + hw/timer/mss-timer.c | 289 ++++++++++++++++++++++++++++ include/hw/arm/msf2-soc.h | 66 +++++++ include/hw/misc/msf2-sysreg.h | 77 ++++++++ include/hw/ssi/mss-spi.h | 58 ++++++ include/hw/timer/mss-timer.h | 64 +++++++ 15 files changed, 1454 insertions(+) create mode 100644 hw/arm/msf2-soc.c create mode 100644 hw/arm/msf2-som.c create mode 100644 hw/misc/msf2-sysreg.c create mode 100644 hw/ssi/mss-spi.c create mode 100644 hw/timer/mss-timer.c create mode 100644 include/hw/arm/msf2-soc.h create mode 100644 include/hw/misc/msf2-sysreg.h create mode 100644 include/hw/ssi/mss-spi.h create mode 100644 include/hw/timer/mss-timer.h -- 2.5.0
