[PATCH 08/24] physmem: Move TCG CPU IOTLB methods around


From: Philippe Mathieu-Daudé
Subject: [PATCH 08/24] physmem: Move TCG CPU IOTLB methods around
Date: Thu, 18 Apr 2024 21:25:07 +0200

The next commit will restrict TCG specific code in physmem.c
using some #ifdef'ry. In order to keep it simple, move
iotlb_to_section() and memory_region_section_get_iotlb()
around close together.
