From mboxrd@z Thu Jan 1 00:00:00 1970 From: Valentin Longchamp Date: Wed, 30 Apr 2014 15:01:48 +0200 Subject: [U-Boot] [PATCH 7/8] kmp204x: add workaround for A-004849 In-Reply-To: <1398862909-17580-1-git-send-email-valentin.longchamp@keymile.com> References: <1398862909-17580-1-git-send-email-valentin.longchamp@keymile.com> Message-ID: <1398862909-17580-8-git-send-email-valentin.longchamp@keymile.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This should prevent the problems that the CCF can deadlock with certain traffic patterns. This also fixes the workaround for A-006559 that was not correctly implemented before.
