From e82a316d7f9425943d86c1ed61c5cf57b0d5b188 Mon Sep 17 00:00:00 2001 From: Kuo-Jung Su Date: Wed, 15 May 2013 15:29:23 +0800 Subject: [PATCH] usb: ehci: add Faraday USB 2.0 EHCI support This patch adds support to both Faraday FUSBH200 and FOTG210, the differences between Faraday EHCI and standard EHCI are listed bellow: 1. The PORTSC starts at 0x30 instead of 0x44. 2. The CONFIGFLAG(0x40) is not only un-implemented, and also has its address space removed. 3. Faraday EHCI is a TDI design, but it doesn't compatible with the general TDI implementation found at both U-Boot and Linux. 4. The ISOC descriptors differ from standard EHCI in several ways. But since U-boot doesn't support ISOC, we don't have to worry about that.
