Subject: [PATCH 2/2] hplance: fix ram size in comment
Date: Thu,  5 Jun 2014 11:01:22 +0800	[thread overview]
Message-ID: <1401937282-18345-3-git-send-email-akong@redhat.com> (raw)
In-Reply-To: <1401937282-18345-1-git-send-email-akong@redhat.com>

drivers/net/ethernet/amd/hplance.h:
 #define HPLANCE_MEMOFF 0x8000   /* struct lance_init_block */
 #define HPLANCE_NVRAMOFF 0xC008 /* etheraddress as one *nibble* per byte */

The offset of RAM start is 0x8000, the offset of RAM end is 0xC008,
so the RAM size is 16392 bytes.
