Subject: [PATCH 3/3] mtd: bcm47xxsflash: define opcodes
Date: Wed, 6 Mar 2013 12:01:35 +0100 [thread overview]
Message-ID: <1362567695-17523-3-git-send-email-zajec5@gmail.com> (raw)
In-Reply-To: <1362567695-17523-1-git-send-email-zajec5@gmail.com>
We need them to add erase/write support. This may duplicate some defines
with bcma and/or ssb code, but it makes more sense to keep that in
bcm47xxsflash which is supposed to work with both buses.
Duplicated defines will be removed from ssb/bcma.
