[PATCH v2 10/21] hw/sh4: Open-code pflash_cfi02_register()


From: Philippe Mathieu-Daudé
Subject: [PATCH v2 10/21] hw/sh4: Open-code pflash_cfi02_register()
Date: Mon, 9 Jan 2023 13:08:22 +0100

pflash_cfi02_register() hides an implicit sysbus mapping of
MMIO region #0. This is not practical in a heterogeneous world
where multiple cores use different address spaces. In order to
remove pflash_cfi02_register() from the pflash API, open-code it
as a qdev creation call followed by an explicit sysbus mapping.
