The original AST2700 FC support series [1] is fairly large, making it
difficult to review all changes together.
To help speed up the review process, this series extracts the SCU/FMC-related
refactoring into a standalone prerequisite series.
v1:
Compared with the original series, the SCU preparation patch has been
split into three smaller patches:
Introduce Aspeed2700SCUState.
Convert AST1700/AST27x0 users to the new SCU subclass.
Move the SCU link property into the AST27x0-specific coprocessor
implementation.
In addition, the SCUIO reset handling has been separated into an
independent patch.
This series contains no functional changes. It is purely a refactoring
to isolate AST2700-specific SCU support from the generic implementation
and prepare for the subsequent AST2700 FC support.
v2:
1. Pass realized PSP SoC to SSP/TSP initialization
2. Share single SCUIO instance across PSP, SSP, and TSP
3. Share FMC controller with SSP and TSP
4. Add Data FIFO-based flash access support for
