Initialises the SMP mailbox area in the SCU at 0x1e6e2180 with default values 2. Copies a stub named 'mailbox_insn' from flash to the SCU, just above the mailbox area 3. Sets AST_SMP_MBOX_FIELD_READY to a magic value to indicate the secondary can begin execution from the stub 4. The stub waits until the AST_SMP_MBOX_FIELD_GOSIGN register is set to a magic value 5. Jumps to the address in AST_SMP_MBOX_FIELD_ENTRY, starting Linux Linux indicates it is ready by writing the address of its entrypoint function to AST_SMP_MBOX_FIELD_ENTRY and the 'go' magic number to AST_SMP_MBOX_FIELD_GOSIGN. The secondary CPU sees this at step 4 and breaks out of it's loop. To be compatible, a fixed qemu stub is loaded into the mailbox area. As qemu can ensure the stub is loaded before execution starts, we do not need to emulate the AST_SMP_MBOX_FIELD_READY behaviour of u-boot. The secondary CPU's program counter points to the beginning of the stub, allowing qemu to start secondaries at step four. Reboot behaviour is preserved by resetting AST_SMP_MBOX_FIELD_GOSIGN when the secondaries are reset. This is only configured when the system is booted with -kernel and qemu does not execute u-boot first.

} -- 2.20.1 From: Richard Henderson <richard.henderson@linaro.org> Use the "normal" memory access functions, rather than the softmmu internal helper functions directly. Since fb901c905dc3, cpu_mem_index is now a simple extract from env->hflags and not a large computation. Which means that it's now more work to pass around this value than it is to recompute it. This only adjusts the primitives, and does not clean up all of the uses within sve_helper.c.

We have open-coded this for sve_ld1_r, but for correctness with MTE we will need this for all of the memory operations. Create a structure that holds the bounds of active elements, and metadata for two pages. Add routines to find those active elements, lookup the pages, and run watchpoints for those pages. Temporarily mark the functions unused to avoid Werror.

If the reg is entirely inaccessible, do not register it at all. If the reg is for EL2, and EL3 is present but EL2 is not, either discard, squash to res0, const, or keep unchanged. Per rule RJFFP, mark the 4 aarch32 hypervisor access registers with ARM_CP_EL3_NO_EL2_KEEP, and mark all of the EL2 address translation and tlb invalidation "regs" ARM_CP_EL3_NO_EL2_UNDEF. Mark the 2 virtualization processor id regs ARM_CP_EL3_NO_EL2_C_NZ. This will simplify cpreg registration for conditional arm features.

Some of the changes we want to make in the near future, to align with real components (e.g. the GIC-700), will break compatibility for existing firmware. Introduce two new properties to the DT generated on machine generation: - machine-version-major To be incremented when a platform change makes the machine incompatible with existing firmware. - machine-version-minor To be incremented when functionality is added to the machine without causing incompatibility with existing firmware. to be reset to 0 when machine-version-major is incremented. This versioning scheme is *neither*: - A QEMU versioned machine type; a given version of QEMU will emulate a given version of the platform. - A reflection of level of SBSA (now SystemReady SR) support provided. The version will increment on guest-visible functional changes only, akin to a revision ID register found on a physical platform. These properties are both introduced with the value 0. (Hence, a machine where the DT is lacking these nodes is equivalent to version 0.0.)
