This is a driver for the S6E63D6 SPI OLED display controller from Samsung.
It only provides access to controller's registers so the client can freely
configure it.

Some SPI devices have special requirements on chip-select handling.
With this patch we can use a GPIO as a chip-select and strictly follow
the SPI_XFER_BEGIN and SPI_XFER_END flags.

NetLoop polls every cycle with getenv some environment variables.
This is horribly slow, especially when the environment is big.
This patch reads only the environment variables in NetLoop,
when they were changed.
Also moved the init part of the NetLoop function in a seperate
function.

A forward port of the last version to work with the newer smc911x driver.
I only have a board with a LAN9218 part on it, so that is the only one
I've tested. But there isn't anything in this that would make it terribly
chip specific afaik.

We're passing a volatile pointer to a function which is expecting a non-
volatile pointer. That's potentially dangerous, so gcc warns about it.
Confirmed with ELDK 4.2 (GCC 4.2.2) and Sourcey G++ 4.2 (GCC 4.2.3).
To fix this, we add a volatile attribute to the argument in question.
The virt_to_phys function in Linux kernel also does the same thing.

With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX)
which might need different software handling. For this, GPIO pin 171 (GPIO
module 6, offset 11) can be used to check for board revision. If this pin
is low, we have a rev C board. Else it must be a revision Ax or Bx board.
To handle board differences you can call function beagle_get_revision().
E.g.:
if (beagle_get_revision()) {
/* do special revision C stuff here */
}

Looks like the initcode updates fell out of order during my merges. The
patch that really fixes up this code is part of power-on overhaul and so
is too large for merging at this point. Instead, we can disable the code
as no currently in-tree board depends on it. The next merge window will
fix things up properly.

This patch clarifies the way m68k passes linux boot argument.
The one gotcha here is that the assembly instruction that

Although load address and image start address are same address,
bootm command always does memmove.
That is unnecessary memmove and can be taken few milliseconds
(about 500 msec to 1000 msec).
If skip this memmove, we can reduce the boot time.
