2021-03-10hw/timer/renesas_tmr: Fix use of uninitialized data in read_tcnt()Peter Maydell
The read_tcnt() function calculates the TCNT register values for the two channels of the timer module; it sets these up in the local tcnt[] array, and eventually returns either one or both of them, depending on whether the access is 8 or 16 bits. However, not all of the code paths through this function set both elements of this array: if the guest has programmed the TCCR.CSS register fields to values which are either documented as not to be used or which QEMU does not implement, then the function will return uninitialized data. (This was spotted by Coverity.) Add the missing CSS cases to this code, so that we return a consistent value instead of uninitialized data, and so the code structure indicates what's happening.

The SSE-300 has a new register block CPU<N>_PWRCTRL. There is one instance of this per CPU in the system (so just one for the SSE-300), and as well as the usual CIDR/PIDR ID registers it has just one register, CPUPWRCFG. This register allows the guest to configure behaviour of the system in power-down and deep-sleep states. Since QEMU does not model those, we make the register a dummy reads-as-written implementation.

2021-03-08hw/misc/iotkit-sysctl: Handle SSE-300 changes to PDCM_PD_*_SENSE registersPeter Maydell
The sysctl PDCM_PD_*_SENSE registers control various power domains in the system and allow the guest to configure which conditions keep a power domain awake and what power state to use when the domain is in a low power state. QEMU doesn't model power domains, so for us these registers are dummy reads-as-written implementations. The SSE-300 has a different power domain setup, so the set of registers is slightly different: Offset SSE-200 SSE-300 --------------------------------------------------- 0x200 PDCM_PD_SYS_SENSE PDCM_PD_SYS_SENSE 0x204 reserved PDCM_PD_CPU0_SENSE 0x208 reserved reserved 0x20c PDCM_PD_SRAM0_SENSE reserved 0x210 PDCM_PD_SRAM1_SENSE reserved 0x214 PDCM_PD_SRAM2_SENSE PDCM_PD_VMR0_SENSE 0x218 PDCM_PD_SRAM3_SENSE PDCM_PD_VMR1_SENSE Offsets 0x200 and 0x208 are the same for both, so handled in a previous commit; here we deal with 0x204, 0x20c, 0x210, 0x214, 0x218.

The SSE-300's iokit-sysctl device is similar to the SSE-200, but some registers have moved address or have different behaviours. In this commit we add case statements for the registers where the SSE-300 and SSE-200 have the same behaviour. Some registers are the same on all SSE versions and so need no code change at all. Putting both of these categories together covers: 0x0 SECDBGSTAT 0x4 SECDBGSET 0x8 SECDBGCLR 0xc SCSECCTRL 0x10 CLK_CFG0 -- this is like SSE-200 FCLK_DIV but with a different set of clocks being controlled; our implementation is a dummy reads-as-written anyway 0x14 CLK_CFG1 -- similar to SSE-200 SYSCLK_DIV; our implementation is a dummy 0x18 CLK_FORCE -- similar to SSE-200 but different bit allocations; we have a dummy implementation 0x100 RESET_SYNDROME -- bit allocation differs from SSE-200 but our implementation is a dummy 0x104 RESET_MASK -- bit allocation differs from SSE-200 but our implementation is a dummy 0x108 SWRESET 0x10c GRETREG 0x200 PDCM_PD_SYS_SENSE -- some bit allocations differ, but our implementation is a dummy We also need to migrate the state of these registers which are shared between the SSE-200 and SSE-300, so update the vmstate 'needed' function to do this.

2021-03-08hw/arm/armsse: Introduce SSE subsystem version propertyPeter Maydell
We model Arm "Subsystems for Embedded" SoC subsystems using generic code which is split into various sub-devices which are configurable by QOM properties to handle the behaviour differences between the SSE subsystems we implement. Currently the only sub-device which needs to change is the IOTKIT_SYSCTL device, and we do this with a mix of properties that directly specify divergent behaviours (eg CPUWAIT_RST) and passing it the SYS_VERSION register value as a way for it to distinguish IoTKit from SSE-200. The "pass SYS_VERSION" approach is already a bit hacky, since the IOTKIT_SYSCTL device has to know that the different part of the register value happens to be bits [31:28]. For SSE-300 this register is renamed SOC_IDENTITY and has a different format entirely, all of whose fields can be configured by the SoC integrator when they integrate the SSE into their SoC, and so "pass SYS_VERSION" breaks down completely. Switch to using a simple integer property representing an internal-to-QEMU enumeration of the SSE flavour. For the moment we only need this in IOTKIT_SYSCTL, but as we add SSE-300 support a few of the other devices will also need to know. We define and permit a value for the SSE-300 so we can start using it in subsequent commits which add SSE-300 support. The now-redundant is_sse200 flag in IoTKitSysCtl will be removed in the following commit.
