We're going to remove the FIRMWARE_NAME_MAX definition in order to avoid any
firmware name length restriction.
This patch eplaces the shared FIRMWARE_NAME_MAX definition with a libertas
local one.

The card firmware does not set the Command Download Ready interrupt bit
when IEEE PS mode is enabled, preventing the driver from sending
commands (such as the command to exit IEEE PS mode) since there is no
indication that the card is ready to accept commands.
This patch works around the problem by using the the TX Download Ready
bit in place of the Command Download Ready Bit while in IEEE PS mode.
TX Download Ready is set in IEEE PS mode.

This removes the dependency on GPIO framework and lets the SPI host
driver handle the chip select. The SPI host driver is required to keep
the CS active for the entire message unless cs_change says otherwise.
This patch collects the two/three single SPI transfers into a message.
Also the delay in read path in case use_dummy_writes are not used is
moved into the SPI host driver.

The comment (which I remove) says that the translation is done SPI routines.
IMHO this can't work because the SPI driver does not know whether the incomming
bytes are part of the registers/bytes which need to be flipped or part of
packet data which has to remain untouched.
While adding le helpers I also removed spu_write_u32() which has no users.

The GPSI interface driver does not re-enable the Card Event Interrupt, which
causes problems after a card event (for example: link-loss) comes in. This
can lead, for example, to the card failing to re-associate. This patch
ensures that we re-enable the Card Event Interrupt when we handle card events.

Currently, the libertas main thread contends with the spi driver thread
in the TX path. To improve throughput, ensure that the driver thread
has higher scheduling priority than the libertas main thread. Do this
by making the libertas spi driver thread a low priority real time
thread.
We measured an average throughput improvement of 13%.

In certain cases it is required to perform board specific actions
before activating libertas G-SPI interface. These actions may include
power up of the chip, GPIOs setup, proper pin-strapping and SPI
controller config.
This patch adds ability to call board specific setup/teardown methods

Add initial support for libertas devices using a GSPI interface. This has
been tested with the 8686.
GSPI is intended to be used on embedded systems. Board-specific parameters are
required (see libertas_spi.h).
Thanks to everyone who took a look at the earlier versions of the patch.
