Subject: [PATCH v2 3/5] ARM: ep93xx: increase NR_BANKS to 16 for support of 128MB RAM
Date: Sun, 12 Jun 2011 17:04:58 +0200	[thread overview]
Message-ID: <1307891100-31123-4-git-send-email-ynezz@true.cz> (raw)
In-Reply-To: <1307891100-31123-1-git-send-email-ynezz@true.cz>

I've got hands on one ts-7300 board, which is equiped with 128MB RAM in two
64MB memory chips, so it's 16 banks/8MB each. Without this patch, the bootmem
init code complains about small NR_BANKS number and only lower 64MB is
accessible.
