[PATCH v5 06/10] hw/fsi: Aspeed APB2OPB interface |
|
Date: |
Wed, 11 Oct 2023 10:13:35 -0500 |
This is a part of patchset where IBM's Flexible Service Interface is
introduced.
An APB-to-OPB bridge enabling access to the OPB from the ARM core in
the AST2600. Hardware limitations prevent the OPB from being directly
mapped into APB, so all accesses are indirect through the bridge.
