Include sysemu/sysemu.h a lot less In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/qdev-core.h includes sysemu/sysemu.h since recent commit e965ffa70a "qdev: add qdev_add_vm_change_state_handler()". This is a bad idea: hw/qdev-core.h is widely included. Move the declaration of qdev_add_vm_change_state_handler() to sysemu/sysemu.h, and drop the problematic include from hw/qdev-core.h. Touching sysemu/sysemu.h now recompiles some 1800 objects. qemu/uuid.h also drops from 5400 to 1800. A few more headers show smaller improvement: qemu/notify.h drops from 5600 to 5200, qemu/timer.h from 5600 to 4500, and qapi/qapi-types-run-state.h from 5500 to 5000.

RISC-V: Mark ROM read-only after copying in code The sifive_u machine already marks its ROM readonly however it has the wrong base address for its mask ROM. This patch fixes the sifive_u mask ROM base address. This commit makes all other boards consistently use mask_rom as the variable name for their ROMs. Boards that use device tree now check that that the device tree fits in the assigned ROM space using the new qemu_fdt_totalsize(void *fdt) interface, adding a bounds check and error message. This can detect truncation.

riscv/virt: Increase flash size Coreboot developers have requested that they have at least 32MB of flash to load binaries. We currently have 32MB of flash, but it is split in two to allow loading two flash binaries. Let's increase the flash size from 32MB to 64MB to ensure we have a single region that is 32MB. No QEMU release has include flash in the RISC-V virt machine, so this isn't a breaking change.

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

RISC-V: Mark ROM read-only after copying in code The sifive_u machine already marks its ROM readonly however it has the wrong base address for its mask ROM. This patch fixes the sifive_u mask ROM base address. This commit makes all other boards consistently use mask_rom as the variable name for their ROMs. Boards that use device tree now check that that the device tree fits in the assigned ROM space using the new qemu_fdt_totalsize(void *fdt) interface, adding a bounds check and error message. This can detect truncation.

RISC-V: Mark ROM read-only after copying in code The sifive_u machine already marks its ROM readonly however it has the wrong base address for its mask ROM. This patch fixes the sifive_u mask ROM base address. This commit makes all other boards consistently use mask_rom as the variable name for their ROMs. Boards that use device tree now check that that the device tree fits in the assigned ROM space using the new qemu_fdt_totalsize(void *fdt) interface, adding a bounds check and error message. This can detect truncation.

riscv/virt: Manually define the machine Instead of using the DEFINE_MACHINE() macro to define the machine let's do it manually. This allows us to use the machine object to create RISCVVirtState. This is required to add children and aliases to the machine. This patch is no functional change.
