This will allow us to get close to the Linux AArch64 ABI for MTE, which allows tag memory only on ram-backed VMAs. The real ABI allows tag memory on files, when those files are on ram-backed filesystems, such as tmpfs. We will not be able to implement that in QEMU linux-user. Thankfully, anonymous memory for malloc arenas is the primary consumer of this feature, so this restricted version should still be of use.

Use g2h_untagged on values returned from target_mmap, as the kernel never applies a tag itself. Use g2h_untagged on all pc values. The only current user of tags, aarch64, removes tags from code addresses upon branch, so "pc" is always untagged. Use g2h with the cpu context on hand wherever possible.

Each Nuvoton SoC has 16 System Management Bus (SMBus). These buses compliant with SMBus and I2C protocol. This patch implements the single-byte mode of the SMBus. In this mode, the user sends or receives a byte each time. The SMBus device transmits it to the underlying i2c device and sends an interrupt back to the QEMU guest.

In FIFO, the user transmits or receives at most 16 bytes at a time. The FIFO mode allows the module to transmit large amount of data faster than single byte mode. Since we only added the device in a patch that is only a few commits away in the same patch set. We do not increase the VMstate version number in this special case.

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.
