This patch adds a driver for Freescale Colfire Queued SPI bus.
Coded to work with 8 bits per transfer to use with SPI flash.
CPOL, CPHA, and CS_ACTIVE_HIGH can be configured.

Tested with MCF5270 which have 4 chip selects.

Activate by #define CONFIG_CF_QSPI in board config.

The SPI pins are routed to header J8 for testing SPI functionality. A
Spansion flash has been wired up and tested on this header.

This patch breaks support for the second TSEC interface, since the GPIO
pin used as a chip select is pinmuxed with some of the TSEC pins.

The MPC8308RDB Reference Manual states that no bits in the SPMODE
register are allowed to change while the enable (EN) bit is set.

This driver changes the character length bits (LEN) while the enable
(EN) bit is set. Clearing the EN bit while changing the LEN bits makes
the driver work correctly on MPC8308RDB.

Change hashtable so that a callback function will decide whether a
variable can be overwritten, and possibly apply the changes.

So add a new field to struct hsearch_data:

 o "apply" callback function to check whether a variable can be
    overwritten, and possibly immediately apply the changes;
    when NULL, no check is performed.

And a new argument to himport_r():
 o "do_apply": whether to call the apply callback function

NOTE: This patch does not change the current behavior.

The logic of checking special parameters (e.g. baudrate, stdin, stdout,
for a valid value and/or whether can be overwritten) and applying the
new value to the running system is now all within a single function
env_check_apply() which can be called whenever changes are made
to the environment, no matter if by set, default or import.

With this patch env_check_apply() is only called by "env set",
retaining previous behavior.

Signed-off-by: NIwo Mergler <Iwo.Mergler@netcommwireless.com>

The third parameter to ALLOC_CACHE_ALIGN_BUFFER is not size (as named),
but rather count (number of elements of the type to allocate). The
current code ends up allocating one copy of env_t for each byte in its
size, which quite possibly ends up overflowing RAM.

This fixes a bug in commit 3801a15f "env_nand: align NAND buffers".

Remove linker command line options from the SPL makefile
that force the inclusion of unreferenced command code from
linked object files. As commands are not used in the SPL,
these options resulted in an unnecessary increase in the
image size, in addition to introducing the possibility of
tricky link errors in the case where the command code
contained symbols that were not resolved by linking in the
limited objects compiled in the SPL build.
