[PATCH 0/5] Introduce AST27x0 multi-SoC machine

[Steven Lee]

This patch series introduces full cores support for the AST27x0 SoC,
along with necessary updates to the ASPEED AST27x0 SOC.

The AST27x0 SoC is a new family of ASPEED SoCs featuring 4 Cortex-A35
cores and 2 Cortex-M4 cores. This patch set adds the following updates:

1. Public API updates:
   Modifies the sdhci_attach_drive and write_boot_rom functions to make them
   accessible for broader usage.

2. SoC memory updates:
   Maps unimplemented devices in the AST27x0 memory space.

3. AST27x0 CM4 SoC integration:
   Adds basic support for the AST27x0 CM4 SoC.

4. AST2700-FC machine:
   Introduces a new AST2700-FC machine which supports emulating 4
   cortex-a35 cores and 2 coretex-m4 cores.

5. Documentation:
   Updates the ASPEED documentation to include usage of the new
   ast2700-fc machine.

This series has been tested using ASPEED SDK image by the following
