From mboxrd@z Thu Jan 1 00:00:00 1970 From: =?utf-8?Q?Beno=C3=AEt_Th=C3=A9baudeau?= Date: Thu, 9 Aug 2012 23:52:08 +0200 (CEST) Subject: [U-Boot] [PATCH v3 4/8] usb_storage: Restore non-EHCI support In-Reply-To: <56898359.292142.1342729095746.JavaMail.root@advansee.com> Message-ID: <868269397.2236815.1344549128022.JavaMail.root@advansee.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 commit 5dd95cf made the MSC driver EHCI-specific. This patch restores a basic support of non-EHCI HCDs, like before that commit. The fallback transfer size is certainly not optimal, but at least it should work like before.
