Subject: [U-Boot] [PATCH v5 04/14] sf: probe: Code cleanup
Date: Wed, 28 Oct 2015 00:07:46 +0530 [thread overview]
Message-ID: <1445971076-17270-4-git-send-email-jteki@openedev.com> (raw)
In-Reply-To: <1445971076-17270-1-git-send-email-jteki@openedev.com>
- Move bar read code below the bar write hance both
at once place, hence it easy for #ifdef macro only
