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
