From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eli Billauer Date: Thu, 12 Jun 2014 12:41:09 +0300 Subject: [U-Boot] [PATCH] mmc: sdhci: Fixed timeout for sdhci_send_command() In-Reply-To: <1402566069-8061-1-git-send-email-eli.billauer@gmail.com> References: <1402566069-8061-1-git-send-email-eli.billauer@gmail.com> Message-ID: <1402566069-8061-2-git-send-email-eli.billauer@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The current wait loop just reads the status 10000 times, which makes the actual timeout period platform-dependent. The udelay() call within the loop makes the new timeout ~100 ms.
