This patch corrects the following issues
1) Write the correct M/T Stop value to I2CSTAT after i2c write.
According to the spec, after finish the data transmission, we should
write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of
a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA).
2) Not split the write to I2CSTAT into 2 steps in i2c read.
According to the spec, we should write the combined M/R Start value to
I2CSTAT after setting the slave address to I2CDS
3) Fix the mistake of making an equality check to an assignment.
In the case of I2C write with the zero-length address, while tranfering the
data, it should be an equality check (==) instead of an assignment (=).

Implements the tstc() interface for the serial driver. Multiplexing
the console between the serial port and a keyboard uses a polling
method of checking if characters are available; this means that the
serial console must be non-blocking when attempting to read
characters.

If the NAND is locked tight, commands such as lock and unlock will not
work, but the NAND chip may not report an error. Check the lock tight
status before attempting such operations so that an error status can be
reported if we know the operation will not succeed.

Add driver for tegra SPI "SLINK" style driver. This controller is
similar to the tegra20 SPI "SFLASH" controller. The difference is
that the SLINK controller is a genernal purpose SPI controller and the
SFLASH controller is special purpose and can only talk to FLASH
devices. In addition there are potentially many instances of an SLINK
controller on tegra and only a single instance of SFLASH. Tegra20 is
currently ths only version of tegra that instantiates an SFLASH
controller.
This driver supports basic PIO mode of operation and is configurable
(CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4
devices per controller may be attached, although typically only a
single chip select line is exposed from tegra per controller so in
reality this is usually limited to 1.
To enable this driver, use CONFIG_TEGRA_SLINK

CONFIG_ARM_DCC_MULTI should be also removed in the patch
"serial: Remove CONFIG_SERIAL_MULTI from serial drivers"
(sha1: a382725060)
Because the driver defines serial_* functions
which cause conflict with serial.c (multiple definition of serial_*)
Removing CONFIG_SERIAL_MULTI function also require to define
default_serial_console for cases where another serial driver
is not available in the system.

Currently we have "unsigned long blkcnt" which is fine with
CONFIG_SYS_64BIT_LBA undefined because "lbaint_t" is basically the same
"unsigned long".
If CONFIG_SYS_64BIT_LBA gets defined "lbaint_t" is defined as "unsigned
long long".
Even though not many embedded systems have CONFIG_SYS_64BIT_LBA defined
it's good to have types in function implementation that match exactly
with prototypes.

System ACE compact flash controller supports either 8-bit (default) or
16-bit data transfers. And in corresponding driver we need to implement
read/write of 16-bit data words properly for both modes of operation.
In existing code if width==8 both branches get executed which may cause
unexpected behavior of SystemAce controller.
Addition of "else" fixes described issue and execution is done as
expected for both (8-bit and 16-bit) data bus widths.
