Subject: [PATCH v6 11/36] mtd: st_spi_fsm: Use device size to determine address width
Date: Thu, 20 Mar 2014 09:20:43 +0000 [thread overview]
Message-ID: <1395307268-12721-12-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1395307268-12721-1-git-send-email-lee.jones@linaro.org>
Take some known parameters, namely size and number of sectors and use
them to determine weather a device can support 32bit addressing or not.
If it can, set the associated flash capability flag for latter use.
