Subject: [PATCH 08/24] physmem: Move TCG CPU IOTLB methods around
Date: Thu, 18 Apr 2024 21:25:07 +0200	[thread overview]
Message-ID: <20240418192525.97451-9-philmd@linaro.org> (raw)
In-Reply-To: <20240418192525.97451-1-philmd@linaro.org>

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.
