Subject: [U-Boot] [PATCH v6 04/23] sf: probe: Code cleanup
Date: Sat,  7 Nov 2015 19:16:18 +0530	[thread overview]
Message-ID: <1446903997-1864-5-git-send-email-jteki@openedev.com> (raw)
In-Reply-To: <1446903997-1864-1-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
  once and readable.
- Move read_cmd_array at top
