[PATCH v1 0/4] hw/arm: versal: Add Cortex-R5s and CRL

Posted by Edgar E. Iglesias 2 years, 1 month ago

From: "Edgar E. Iglesias" <edgar.iglesias@amd.com>

This adds the Versal Cortex-R5s in the Real-Time Processing Unit
(RPU) subsystem.

A model of the Clock/Reset Low-power domain (CRL) is also added
allowing runtime release of the Cortex-R5s. The RPU subsystem
is largely missing but has enough to run simple bare-metal R5
apps.

Cheers,
Edgar

Applied to target-arm.next for 7.1, thanks.
