2018-06-27hw/mips/boston: don't make flash region 'nomigrate'Peter Maydell
Currently we use memory_region_init_rom_nomigrate() to create the "boston.flash" memory region, and we don't manually register it with vmstate_register_ram(). This currently means that its contents are migrated but as a ram block whose name is the empty string; in future it may mean they are not migrated at all. Use memory_region_init_ram() instead. Note that this is a a cross-version migration compatibility break for the "boston" machine.

2018-04-26hw/mips/boston.c: Don't create "null" chardevs for serial devicesPeter Maydell
Following commit 12051d82f004024, UART devices should handle being passed a NULL pointer chardev, so we don't need to create "null" backends in board code. Remove the code that does this and updates serial_hds[].

Now that the memory system correctly handles writes to ROM for guest CPUs that may generate exceptions for decode errors, we can remove the workaround from the boston board.

2017-10-27mips: use object_new() instead of gnew()+object_initialize()Igor Mammedov
object_initialize() is intended for inplace initialization of objects, but here it's first allocated with g_new0() and then initialized with object_initialize(). QEMU already has API to do this (object_new), so do object creation with suitable for usecase API.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-02-24hw/mips: MIPS Boston board supportPaul Burton
Introduce support for emulating the MIPS Boston development board. The Boston board is built around an FPGA & 3 PCIe controllers, one of which is connected to an Intel EG20T Platform Controller Hub. It is used during the development & debug of new CPUs and the software intended to run on them, and is essentially the successor to the older MIPS Malta board. This patch does not implement the EG20T, instead connecting an already supported ICH-9 AHCI controller. Whilst this isn't accurate it's enough for typical stock Boston software (eg. Linux kernels) to work with hard disks given that both the ICH-9 & EG20T implement the AHCI specification. Boston boards typically boot kernels in the FIT image format, and this patch will treat kernels provided to QEMU as such. When loading a kernel directly, the board code will generate minimal firmware much as the Malta board code does. This firmware will set up the CM, CPC & GIC register base addresses then set argument registers & jump to the kernel entry point. Alternatively, bootloader code may be loaded using the bios argument in which case no firmware will be generated & execution will proceed from the start of the boot code at the default MIPS boot exception vector (offset 0x1fc00000 into (c)kseg1). Currently real Boston boards are always used with FPGA bitfiles that include a Global Interrupt Controller (GIC), so the interrupt configuration is only defined for such cases. Therefore the board will only allow use of CPUs which implement the CPS components, including the GIC, and will otherwise exit with a message.

2017-02-23Revert "hw/mips: MIPS Boston board support"Peter Maydell
This reverts commit d3473e147a754e999718bf6fcb015d9978c6a1ee. This commit creates a board which defaults to having 2GB of RAM. Unfortunately on 32-bit hosts we can't create boards with 2GB of RAM, and so 'make check' fails. I missed this during testing of the merge, unfortunately. Luckily the offending commit is the last one in the merge request, so we can just revert it for now. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
