From: Kuo-Jung Su <dant...@faraday-tech.com>
This patch add supports to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI as
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 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 differs from standard EHCI in
several ways. Since U-boot doesn't support ISOC,
we don't have to worry that.
The Faraday FOTG210 is an OTG chip which could operate
as either an EHCI Host or a USB Device as a time.
Changes for v4:
- Use only macro constants and named bit/mask
- Use weak-aliased functions for tdi implementation and
also portsc registers to avoid poluting ehci.h with ifdefs
Changes for v3:
- Coding Style cleanup.
- Drop bit fields from c struct.
- Drop macros for wirtel()/readl(), call them directly.
- Always insert a blank line between declarations and code.
- Replace all the infinite wait loop with a timeout.
- Add '__iomem' to all the declaration of HW register pointers.
Changes for v2:
- Coding Style cleanup.
- Use readl(), writel(), clrsetbits_le32() to replace REG() macros.
- Use structure based hardware registers to replace the macro constants.
- Replace BIT() with BIT_MASK().
- echi-faraday: Remove debug codes.
