A set of cache operations (both invalidation and flush) were redundant
in the S3C HS OTG Samsung driver:

1. s3c_udc_ep0_zlp - to transmit EP0's ZLP packets one don't need to flush
the cache (since it is the zero length transmission)

2. s3c_udc_pre_setup and s3c_ep0_complete_out - cache invalidation is not
needed when the buffer for OUT EP0 transmission is setup, since no data
has yet arrived.

Cache cleanups presented above don't contribute much to transmission speed
up, hence shall be regarded as cosmetic changes.

3. setdma_rx - here the s3c UDC driver's internal buffers were invalidated.
This call is not needed anymore since we reuse the buffers passed from
gadgets. This is a key contribution to transmission speed improvement.

People who write (or scripts that auto-generate) extlinux.conf don't
want to know about HW-specific information such as FDT filenames. Create
a new extlinux.conf tag "fdtdir" that specifies only the directory where
FDT files are located, and defer all knowledge of the filename to U-Boot.
The algorithm implemented is:

==========
if $fdt_addr_r is set:
  if "fdt" tag was specified in extlinux.conf:
    load the FDT from the filename in the tag
  else if "fdtdir" tag was specified in extlinux.conf:
    if "fdtfile" is set in the environment:
      load the FDT from filename in "$fdtfile"
    else:
      load the FDT from some automatically generated filename

if no FDT file was loaded, and $fdtaddr is set:
  # This indicates an FDT packaged with firmware
  use the FDT at $fdtaddr
==========

A small part of an example /boot/extlinux.conf might be:

==========
LABEL primary
        LINUX zImage
        FDTDIR ./

LABEL failsafe
        LINUX bkp/zImage
        FDTDIR bkp/
==========

... with /boot/tegra20-seaboard.dtb or /boot/bkp/tegra20-seaboard.dtb
being loaded by the sysboot/pxe code.

The specification for extlinux.conf[1] states that "fdt" is an alias for
"devicetree". To date, U-Boot only implements "fdt". Rectify that.

The PEXHC PCIe configuration mechanism ensures that the FPGA get
configured at power-up. Since all the PCIe devices should be configured
when the kernel start, u-boot has to take care that the FPGA gets
configured also in other reset scenarios, mostly because of possible
configuration change.

The used mechanism is taken from the km_kirkwood design and adapted to
the kmp204x case (slightly different HW and PCIe configuration).

This patch adds support for using some GPIOs that are connected to the
I2C bus to force the bus lines state and perform some bus deblocking
sequences.

The KM common deblocking algorithm from board/keymile/common/common.c is
used. The GPIO lines used for deblocking the I2C bus are some external
GPIOs provided by the QRIO CPLD:
  - SCL = GPIOA_20
  - SDA = GPIOA_21

The QRIO GPIOs act in an open-drain-like manner, for 0 the line is
driven low and for 1 the GPIO is set as input and the line gets
pulled-up.
