Subject: [PATCH v5 03/13] include/hw/cxl/cxl_device: Rename mem_size as static_mem_size for type3 memory devices
Date: Mon,  4 Mar 2024 11:33:58 -0800	[thread overview]
Message-ID: <20240304194331.1586191-4-nifan.cxl@gmail.com> (raw)
In-Reply-To: <20240304194331.1586191-1-nifan.cxl@gmail.com>

From: Fan Ni <fan.ni@samsung.com>

Rename mem_size as static_mem_size for type3 memdev to cover static RAM and
pmem capacity, preparing for the introduction of dynamic capacity to support
dynamic capacity devices.

Signed-off-by: Fan Ni <fan.ni@samsung.com>
