This patchseries adds support for the ARM MPS2/MPS2+ dev board: The MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger FPGA but is otherwise the same as the 2). Since the CPU itself and most of the devices are in the FPGA, the details of the board as seen by the guest depend significantly on the FPGA image.
We model the following FPGA images: "mps2_an385" -- Cortex-M3 as documented in ARM Application Note AN385 "mps2_an511" -- Cortex-M3 'DesignStart' as documented in AN511 They are fairly similar but differ in the details for some peripherals. Further info and links to all the documentation for the board and the various FPGA images can be found here: https://developer.arm.com/products/system-design/development-boards/cortex-m-prototyping-system This patchset adds the boards themselves, and the UART, timer and system-controller devices they need. There are a number of other devices on the board which are not yet modelled (notably more GPIOs, a watchdog, another different kind of timer, and a display device), but this minimal set is sufficient to boot the "hello world" binary of the Zephyr RTOS and the "blinky" binary of the mbed RTOS. [To run the zephyr binary you also need this fix: http://patchwork.ozlabs.org/patch/782811/ which is in the target-arm pullreq I just sent so should get into master in a few days.] We can add more devices to the model later, but I figured this was a sufficient place to start. The underlying motivation here is that the v8M work that I have planned will need a board, and there is a v8M FPGA image for the MPS2 that we can use. It's also perhaps a more useful M profile board for general purposes than the stellaris boards (64K RAM) or the Netduino2 (128K RAM), since it has 16MB of RAM. thanks -- PMM Peter Maydell (7): hw/arm/mps2: Implement skeleton mps2-an385 and mps2-an511 board models hw/char/cmsdk-apb-uart.c: Implement CMSDK APB UART hw/arm/mps2: Add UARTs hw/char/cmsdk-apb-timer: Implement CMSDK APB timer device hw/arm/mps2: Add timers hw/misc/mps2_scc: Implement MPS2 Serial Communication Controller hw/arm/mps2: Add SCC hw/arm/Makefile.objs | 1 + hw/char/Makefile.objs | 1 + hw/misc/Makefile.objs | 1 + hw/timer/Makefile.objs | 1 + include/hw/char/cmsdk-apb-uart.h | 78 ++++++++ include/hw/misc/mps2-scc.h | 43 ++++ include/hw/timer/cmsdk-apb-timer.h | 59 ++++++ hw/arm/mps2.c | 378 +++++++++++++++++++++++++++++++++++ hw/char/cmsdk-apb-uart.c | 390 +++++++++++++++++++++++++++++++++++++ hw/misc/mps2-scc.c | 310 +++++++++++++++++++++++++++++ hw/timer/cmsdk-apb-timer.c | 253 ++++++++++++++++++++++++ default-configs/arm-softmmu.mak | 6 + hw/char/trace-events | 9 + hw/misc/trace-events | 8 + hw/timer/trace-events | 5 + 15 files changed, 1543 insertions(+) create mode 100644 include/hw/char/cmsdk-apb-uart.h create mode 100644 include/hw/misc/mps2-scc.h create mode 100644 include/hw/timer/cmsdk-apb-timer.h create mode 100644 hw/arm/mps2.c create mode 100644 hw/char/cmsdk-apb-uart.c create mode 100644 hw/misc/mps2-scc.c create mode 100644 hw/timer/cmsdk-apb-timer.c -- 2.7.4
