2021-03-06accel/tcg: move CF_CLUSTER calculation to curr_cflagsAlex Bennée
There is nothing special about this compile flag that doesn't mean we can't just compute it with curr_cflags() which we should be using when building a new set.

2021-03-06accel/tcg: rename tb_lookup__cpu_state and hoist state extractionAlex Bennée

2021-03-06hw/arm/mps2-tz: Allow PPCPortInfo structures to specify device interruptsPeter Maydell
The mps2-tz code uses PPCPortInfo data structures to define what devices are present and how they are wired up. Currently we use these to specify device types and addresses, but hard-code the interrupt line wiring in each make_* helper function. This works for the two boards we have at the moment, but the AN524 has some devices with different interrupt assignments. This commit adds the framework to allow PPCPortInfo structures to specify interrupt numbers. We add an array of interrupt numbers to the PPCPortInfo struct, and pass it through to the make_* helpers. The following commit will change the make_* helpers over to using the framework.

2021-03-06hw/arm/mps2-tz: Correct wrong interrupt numbers for DMA and SPIPeter Maydell
On the MPS2 boards, the first 32 interrupt lines are entirely internal to the SSE; interrupt lines for devices outside the SSE start at 32. In the application notes that document each FPGA image, the interrupt wiring is documented from the point of view of the CPU, so '0' is the first of the SSE's interrupts and the devices in the FPGA image itself are '32' and up: so the UART 0 Receive interrupt is 32, the SPI #0 interrupt is 51, and so on. Within our implementation, because the external interrupts must be connected to the EXP_IRQ[0...n] lines of the SSE object, we made the get_sse_irq_in() function take an irqno whose values start at 0 for the first FPGA device interrupt. In this numbering scheme the UART 0 Receive interrupt is 0, the SPI #0 interrupt is 19, and so on. The result of these two different numbering schemes has been that half of the devices were wired up to the wrong IRQs: the UART IRQs are wired up correctly, but the DMA and SPI devices were passing start-at-32 values to get_sse_irq_in() and so being mis-connected. Fix the bug by making get_sse_irq_in() take values specified with the same scheme that the hardware manuals use, to avoid confusion.

2021-03-06hw/misc/mps2-scc: Implement CFG_REG5 and CFG_REG6 for MPS3 AN524Peter Maydell
The AN524 version of the SCC interface has different behaviour for some of the CFG registers; implement it. Each board in this family can have minor differences in the meaning of the CFG registers, so rather than trying to specify all the possible semantics via individual device properties, we make the behaviour conditional on the part-number field of the SCC_ID register which the board code already passes us. For the AN524, the differences are: * CFG3 is reserved rather than being board switches * CFG5 is a new register ("ACLK Frequency in Hz") * CFG6 is a new register ("Clock divider for BRAM") We implement both of the new registers as reads-as-written.

2021-03-06hw/arm/mps2-tz: Make number of IRQs board-specificPeter Maydell
The AN524 has more interrupt lines than the AN505 and AN521; make numirq board-specific rather than a compile-time constant. Since the difference is small (92 on the current boards and 95 on the new one) we don't dynamically allocate the cpu_irq_splitter[] array but leave it as a fixed length array whose size is the maximum needed for any of the boards.
