Subject: [PATCH v1 2/3] hw/arm/aspeed_coprocessor: Clarify SCU/SCUIO/FMC fields are shared with PSP SoC to AST2700
Date: Fri, 17 Jul 2026 01:47:04 +0000 [thread overview]
Message-ID: <20260717014701.1683876-3-jamin_lin@aspeedtech.com> (raw)
In-Reply-To: <20260717014701.1683876-1-jamin_lin@aspeedtech.com>
Add a comment above Aspeed27x0CoprocessorState's scu_alias/scuio_alias/
fmc_alias and scu/scuio/fmc fields noting that they are not owned by
the coprocessor: they point at resources owned by the main PSP SoC,
only aliased into this coprocessor's own address space.
No functional change.
