Subject: [PATCH 1/3] target/mips: Support variable page size
Date: Wed,  8 Apr 2020 17:16:18 +0800	[thread overview]
Message-ID: <1586337380-25217-1-git-send-email-chenhc@lemote.com> (raw)

Traditionally, MIPS use 4KB page size, but Loongson prefer 16KB page
size in system emulator. So, let's define TARGET_PAGE_BITS_VARY and
TARGET_PAGE_BITS_MIN to support variable page size.
