Subject: [PATCH 4/5] ARM: dts: aspeed: minipack: Update 64MB FMC flash layout
Date: Mon, 24 Aug 2020 14:19:47 -0700	[thread overview]
Message-ID: <20200824211948.12852-5-rentao.bupt@gmail.com> (raw)
In-Reply-To: <20200824211948.12852-1-rentao.bupt@gmail.com>

From: Tao Ren <rentao.bupt@gmail.com>

Set 64Mb FMC flash layout in Minipack device tree explicitly because the
flash layout was removed from "ast2500-facebook-netbmc-common.dtsi".

Please note "data0" partition' size is updated to 4MB to be consistent
with other Facebook OpenBMC platforms.
