Subject: [PATCH v2] Documentation/admin-guide: mark memmap parameter is supported by a few architectures
Date: Sun, 29 Nov 2020 08:51:21 +1300 [thread overview]
Message-ID: <20201128195121.2556-1-song.bao.hua@hisilicon.com> (raw)
early_param memmap is only implemented on X86, MIPS and XTENSA. To avoid
wasting users’ time on trying this on platform like ARM, mark it clearly.

which limits max address to nn[KMG].
