riscv: sifive_u: Fix broken GEM support At present the GEM support in sifive_u machine is seriously broken. The GEM block register base was set to a weird number (0x100900FC), which for no way could work with the cadence_gem model in QEMU. Not like other GEM variants, the FU540-specific GEM has a management block to control 10/100/1000Mbps link speed changes, that is mapped to 0x100a0000. We can simply map it into MMIO space without special handling using create_unimplemented_device(). Update the GEM node compatible string to use the official name used by the upstream Linux kernel, and add the management block reg base & size to the <reg> property encoding. Tested with upstream U-Boot and Linux kernel MACB drivers.

riscv/sifive_u: Add a serial property to the sifive_u machine At present the board serial number is hard-coded to 1, and passed to OTP model during initialization. Firmware (FSBL, U-Boot) uses the serial number to generate a unique MAC address for the on-chip ethernet controller. When multiple QEMU 'sifive_u' instances are created and connected to the same subnet, they all have the same MAC address hence it creates a unusable network. A new "serial" property is introduced to specify the board serial number. When not given, the default serial number 1 is used.

#include "sysemu/runstate.h"
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/sifive_u: Add L2-LIM cache memory On reset only a single L2 cache way is enabled, the others are exposed as memory that can be used by early boot firmware. This L2 region is generally disabled using the WayEnable register at a later stage in the boot process. To allow firmware to target QEMU and the HiFive Unleashed let's add the L2 LIM (LooselyIntegrated Memory). Ideally we would want to adjust the size of this chunk of memory as the L2 Cache Controller WayEnable register is incremented. Unfortunately I don't see a nice way to handle reducing or blocking out the L2 LIM while still allowing it be re returned to all enabled from a reset.

hw/riscv: sifive_u: Add a dummy DDR memory controller device It is enough to simply map the SiFive FU540 DDR memory controller into the MMIO space using create_unimplemented_device(), to make the upstream U-Boot v2020.07 DDR memory initialization codes happy. Note we do not generate device tree fragment for the DDR memory controller. Since the controller data in device tree consumes a very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the U-Boot source), and it is only needed by U-Boot SPL but not any operating system, we choose not to generate the fragment here. This also means when testing with U-Boot SPL, the device tree has to come from U-Boot SPL itself, but not the one generated by QEMU on the fly. The memory has to be set to 8GiB to match the real HiFive Unleashed board when invoking QEMU (-m 8G). With this commit, QEMU can boot U-Boot SPL built for SiFive FU540 all the way up to loading U-Boot proper from MMC: $ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800) Trying to boot from MMC1 Unhandled exception: Load access fault EPC: 0000000008009be6 TVAL: 0000000010050014 The above exception is expected because QSPI is unsupported yet.

hw/riscv: sifive_u: Support different boot source per MSEL pin state SiFive FU540 SoC supports booting from several sources, which are controlled using the Mode Select (MSEL[3:0]) pins on the chip. Typically, the boot process runs through several stages before it begins execution of user-provided programs. The SoC supports booting from memory-mapped QSPI flash, which is how start_in_flash property is used for at present. This matches MSEL = 1 configuration (QSPI0). Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL). It's not necessary for QEMU to implement the full ZSBL ROM codes, because we know ZSBL downloads the next stage program into the L2 LIM at address 0x8000000 and executes from there. We can bypass the whole ZSBL execution and use "-bios" to load the next stage program directly if MSEL indicates a ZSBL booting flow.

Currently, qemu loader uses fw_jump which has a compile time pre-defined address where fdt & kernel image must reside.

However, fw_dynamic allows the loader to specify the next stage location (i.e. Linux kernel/U-Boot) in memory and other configurable boot options available in OpenSBI.

hw/riscv: sifive_u: Support different boot source per MSEL pin state SiFive FU540 SoC supports booting from several sources, which are controlled using the Mode Select (MSEL[3:0]) pins on the chip. Typically, the boot process runs through several stages before it begins execution of user-provided programs. The SoC supports booting from memory-mapped QSPI flash, which is how start_in_flash property is used for at present. This matches MSEL = 1 configuration (QSPI0). Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL). It's not necessary for QEMU to implement the full ZSBL ROM codes, because we know ZSBL downloads the next stage program into the L2 LIM at address 0x8000000 and executes from there. We can bypass the whole ZSBL execution and use "-bios" to load the next stage program directly if MSEL indicates a ZSBL booting flow.

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.

Parentage is also under program control, so this is a programming error, too. We have a bit over 500 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.

hw/riscv: sifive_u: Support different boot source per MSEL pin state SiFive FU540 SoC supports booting from several sources, which are controlled using the Mode Select (MSEL[3:0]) pins on the chip. Typically, the boot process runs through several stages before it begins execution of user-provided programs. The SoC supports booting from memory-mapped QSPI flash, which is how start_in_flash property is used for at present. This matches MSEL = 1 configuration (QSPI0). Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL). It's not necessary for QEMU to implement the full ZSBL ROM codes, because we know ZSBL downloads the next stage program into the L2 LIM at address 0x8000000 and executes from there. We can bypass the whole ZSBL execution and use "-bios" to load the next stage program directly if MSEL indicates a ZSBL booting flow.

qom: Drop object_property_set_description() parameter @errp object_property_set_description() and object_class_property_set_description() fail only when property @name is not found. There are 85 calls of object_property_set_description() and object_class_property_set_description(). None of them can fail: * 84 immediately follow the creation of the property. * The one in spapr_rng_instance_init() refers to a property created in spapr_rng_class_init(), from spapr_rng_properties[]. Every one of them still gets to decide what to pass for @errp. 51 calls pass &error_abort, 32 calls pass NULL, one receives the error and propagates it to &error_abort, and one propagates it to &error_fatal. I'm actually surprised none of them violates the Error API. What are we gaining by letting callers handle the "property not found" error? Use when the property is not known to exist is simpler: you don't have to guard the call with a check. We haven't found such a use in 5+ years. Until we do, let's make life a bit simpler and drop the @errp parameter.

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.

Firmware (FSBL, U-Boot) uses the serial number to generate a unique MAC address for the on-chip ethernet controller. When multiple QEMU 'sifive_u' instances are created and connected to the same subnet, they all have the same MAC address hence it creates a unusable network.

hw/riscv: sifive_u: Simplify the GEM IRQ connect code a little bit There is no need to retrieve all PLIC IRQ information in order to just connect the GEM IRQ. Use qdev_get_gpio_in() directly like what is done for other peripherals.

riscv: sifive_u: Fix broken GEM support At present the GEM support in sifive_u machine is seriously broken. The GEM block register base was set to a weird number (0x100900FC), which for no way could work with the cadence_gem model in QEMU. Not like other GEM variants, the FU540-specific GEM has a management block to control 10/100/1000Mbps link speed changes, that is mapped to 0x100a0000. We can simply map it into MMIO space without special handling using create_unimplemented_device(). Update the GEM node compatible string to use the official name used by the upstream Linux kernel, and add the management block reg base & size to the <reg> property encoding. Tested with upstream U-Boot and Linux kernel MACB drivers.

hw/riscv: sifive_u: Add a dummy DDR memory controller device It is enough to simply map the SiFive FU540 DDR memory controller into the MMIO space using create_unimplemented_device(), to make the upstream U-Boot v2020.07 DDR memory initialization codes happy. Note we do not generate device tree fragment for the DDR memory controller. Since the controller data in device tree consumes a very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the U-Boot source), and it is only needed by U-Boot SPL but not any operating system, we choose not to generate the fragment here. This also means when testing with U-Boot SPL, the device tree has to come from U-Boot SPL itself, but not the one generated by QEMU on the fly. The memory has to be set to 8GiB to match the real HiFive Unleashed board when invoking QEMU (-m 8G). With this commit, QEMU can boot U-Boot SPL built for SiFive FU540 all the way up to loading U-Boot proper from MMC: $ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800) Trying to boot from MMC1 Unhandled exception: Load access fault EPC: 0000000008009be6 TVAL: 0000000010050014 The above exception is expected because QSPI is unsupported yet.

riscv/sifive_u: Add a serial property to the sifive_u SoC At present the board serial number is hard-coded to 1, and passed to OTP model during initialization. Firmware (FSBL, U-Boot) uses the serial number to generate a unique MAC address for the on-chip ethernet controller. When multiple QEMU 'sifive_u' instances are created and connected to the same subnet, they all have the same MAC address hence it creates a unusable network. A new "serial" property is introduced to the sifive_u SoC to specify the board serial number. When not given, the default serial number 1 is used.
