Subject: [PATCH qemu v1 2/8] hw/pci: Move 'x-256b-flit' property from cxl_root_port to pcie_root_port
Date: Wed,  4 Nov 2026 17:22:36 +0530	[thread overview]
Message-ID: <2052256418.81793792283466.JavaMail.epsvc@epcpadp2new> (raw)
In-Reply-To: <20261104115242.2035807-1-shrihari.s@samsung.com>

Relocate the 'x-256b-flit' property from cxl_root_port to its parent
pcie_root_port so that all root port types inherit the property.

The cxl_root_port and cxl_downstream_port no longer carry a local
property definition; the property is inherited from pcie_root_port
and PCIEPort respectively.
