[PATCH v1 00/10] hw/arm: Add AST1040 peripheral support

[Jamin Lin <jamin_lin@aspeedtech.com>]

This series extends the AST1040 SoC model by adding support for several
peripherals that are compatible with existing AST2700 controller models.

The AST1040 shares a number of peripheral IP blocks with the AST2700,
allowing the existing QEMU models to be reused with minimal changes.
This series adds support for ADC, PECI, GPIO, SGPIO, I2C, and watchdog
controllers, and updates the AST1040 EVB machine to instantiate onboard
I2C devices for validation.

For I2C support, a new AST1040 I2C type is introduced. The model
inherits the AST2700 I2C architecture, including DMA support and
64-bit DMA address registers, while constraining DMA accesses to the
16 MiB HyperRAM address space available on AST1040.

v1:
  1. Support ADC, GPIO, SGPIO, I2C and PECI
