[PATCH 12/20] hw/mips: Open-code pflash_cfi01_register()


From: Philippe Mathieu-Daudé
Subject: [PATCH 12/20] hw/mips: Open-code pflash_cfi01_register()
Date: Wed, 4 Jan 2023 23:04:41 +0100

pflash_cfi01_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 to remove pflash_cfi01_register() from the pflash API,
open-code it as a qdev creation call followed by an explicit
sysbus mapping.
