ed7bdc03eb MMC: DWMMC: Fix FIFO_DEPTH calculation
Current DWMMC driver used to give FIFO underrun/overrun error every 3rd time
for mmc rescan command.
In current code FIFO_DEPTH is getting calculated after reading the default FIFOTH
register and extracting the RX_WMARK bits from it i.e (RX_WMARK = FIFO_DEPTH/2 -1).
Instead of storing the correct value, we were recalculating the FIFO_DEPT each
time which is not correct.

91171091c6 ARM: tegra: make use of negative ENV_OFFSET on NVIDIA boards
Use a negative value of CONFIG_ENV_OFFSET for all NVIDIA reference boards
that store the U-Boot environment in the 2nd eMMC boot partition. This
makes U-Boot agnostic to the size of the eMMC boot partition, which can
vary depending on which eMMC device was actually stuffed into the board.

5c088ee841 env_mmc: allow negative CONFIG_ENV_OFFSET
A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset
from the end of the eMMC device/partition, rather than a forwards offset
from the start.

This is useful when a single board may be stuffed with different eMMC
devices, each of which has a different capacity, and you always want the
environment to be stored at the very end of the device (or eMMC boot
partition for example).

One example of this case is NVIDIA's Ventana reference board.

01b77353e4 fsl_esdhc: Do not clear interrupt status bits until data processed
After waiting for the command completion event, the interrupt status
bits, that occured to be set by that time, are cleared by writing them
back. It is supposed, that it should be command related bits (command
complete and may be command errors).

However, in some cases the DMA already completes by that time before
the full transaction completes. The corresponding DINT bit gets set
and then cleared before even entering the loop, waiting for data part
completion. That waiting loop never gets this bit set, causing the
operation to hang. This is reported to happen, for example, for write
operation of 1 sector to upper area (block #7400000) of SanDisk Ultra II
8GB card.

The solution could be to explicitly clear only command related interrupt
status bits. However, since subsequent processing does not rely on
any command bits state, it could be easier just to remove clearing
of any bits at that point, leaving them all until all data processing
completes. After that the whole register will be cleared at once.

Also, on occasion, interrupts masking moved to before writing the command,
just for the case there should be no chance of interrupt between the first
command and interrupts masking.

a586c0aa21 mmc write bug fix
This patch fixes a bug related to mmc writes.

When doing fatwrites on an SD-Card, MMC bus problems can occur. Depending
on the size of the file, "MMC0: Bus busy timeout!" is reported, resulting
in an SD-Card that is no longer responding.
It appears to be, that set_cluster can be called with a size being zero.
That can be with a file that has a size being an exact multiple
(including 0) of the clustersize, but also for files that are smaller than
the size of one cluster.
The same problem occurs if the "mmc write" command is given with a block
count being 0.

By adding a check for the block count being zero in mmc_write_blocks
(drivers/mmc.c), this problem is solved.

d3e0747846 usb: ehci: add missing cache managment
Commit 8f62ca6 "usb: ehci: Support interrupt transfers via periodic list"
didn't include any cache management in the new interrupt transfer path.
It also added an extra write to or_asynclistaddr in usb_lowlevel_init(),
without having flushed out the data there.

Add the missing cache management calls, so that the code works again.

This allows the USB keyboard on Tegra's Seaboard/Springbank boards to
work.

64cfd3f964 usb: gadget: add Faraday FOTG210 USB gadget support
The Faraday FOTG210 is an OTG chip which could operate
as either an EHCI Host or a USB Device at a time.

e82a316d7f 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.

aa1550588c usb: hub: make minimum power-on delay configurable
This patch makes the minimum power-on delay for USB HUB
become configurable. The original design waits at least
100 msec here, but some EHCI controlers(e.g. Faraday EHCI)
are known to require much longer delay interval.

1dde1423ad usb: ehci: add weak-aliased function for PORTSC
There is at least one non-EHCI compliant controller (i.e. Faraday EHCI)
not only leave RESERVED and CONFIGFLAG registers un-implemented
but also has their address spaces removed.

As an result, the PORTSC register of Faraday EHCI always
starts from 0x30 instead of 0x44 in standard EHCI.

So that we'll need a weak-aliased function for abstraction.

9c6a9d7c8b usb: ehci: prevent bad PORTSC register access
1. The 'index' of ehci_submit_root() is not always > 0.

   e.g.
   While it gets invoked from usb_get_descriptor(),
   the 'index' is always a '0'. (See ch.9 of USB2.0)

2. The PORTSC register is not always required, and thus it
   should only report a port error when necessary.
   It would cause a port scan failure if the ehci_submit_root()
   always gets terminated by a port error.
