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.

Most important registers are those related to DRAM initialization and calibration, where SPL initiates process and waits until certain bit is set/cleared. This patch adds these registers, initializes reset values from user's guide and updates state of registers as SPL expects it.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.

Qemu uses a valid mask to clear unsupported SCR_EL3 bits when emulating SCR_EL3 write, and that mask doesn't include SCR_EL3.HXEn bit even if FEAT_HCX is enabled and exposed to the guest. As a result EL3 writes of that bit are ignored.
