Subject: [RFC PATCH 2/5] ppc/pegasos2: Introduce Pegasos2MachineState structure
Date: Sun, 06 Jun 2021 17:46:35 +0200 [thread overview]
Message-ID: <7ef9d2058fab88cc83c54e0482eeae8e275f0069.1622994395.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1622994395.git.balaton@eik.bme.hu>
Add own machine state structure which will be used to store state
needed for firmware emulation.
