Increase TXFIFOTHRES field value in TXFILLTUNING register of usb for T4 Rev 2.0.
This decreases data burst rate with which data packets are posted from the TX
latency FIFO to compensate for latencies in DDR pipeline during DMA.
This avoids Tx buffer underruns and leads to successful usb writesSigned-off-by: Ramneek Mehresh

The mv_udc is not marvell-specific anymore. The mv_udc is used to drive

The Samsung's UDC driver is not anymore copying data from USB requests to
aligned internal buffers. Now it works directly in data allocated in the
upper layers like UMS, DFU, THOR.This change is possible since those gadgets now must take care to allocate
buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE).This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or
ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer
aligned to cache line in both starting address and its size.
Sometimes it is enough to just use memalign() with size being a
multiplication of cache line size.Test condition

The usb_lowlevel_init() call already fills and passes back struct
ehci_ctrl , which readily contains correctly determined address of
the port register block address computed from values from controller
configuration registers. Leverage this and make use of this value
as this makes the code mode universal, but also gets us rid of the
CONFIG_USB_REG_BASE configuration option.Moreover, this patch cleans up the usb_gadget_register_driver() call
a little by correcting the error handling. Note the usb_lowlevel_init()
and mvudc_probe() are now called in reversed order, but this has no
impact on the code.Signed-off-by: Marek Vasut

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.Signed-off-by: Kuo-Jung Su
