Subject: [U-Boot] [PATCH v3 09/27] sf: Add JEDEC_ID and JEDEC_EXT macro
Date: Thu, 11 Aug 2016 13:37:31 +0530 [thread overview]
Message-ID: <1470902869-22570-9-git-send-email-jteki@openedev.com> (raw)
In-Reply-To: <1470902869-22570-1-git-send-email-jteki@openedev.com>
Few of the flash families with different ext_jedec
have changes in page_size so these macros check these
ext_jedec and assign page_size accordingly
