The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS.
The ngPIXIS has one distinct new feature: the values of the on-board switches
can be selectively overridden with shadow registers. This feature is used to
boot from a different NOR flash bank, instead of having a register dedicated
for this purpose. Because the ngPIXIS is so different from the previous PIXIS,
a new file is introduced: ngpixis.c.
Also update the P2020DS checkboard() function to use the new macros defined
in the header file.

Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx
boards. This makes the code easier to read and more flexible.
Delete pixis.h, because none of the exported functions were actually being
used by any other file. Make all of the functions in pixis.c 'static'.
Remove "#include pixis.h" from every file that has it.
Remove some unnecessary #includes.
Make 'pixis_base' into a macro, so that we don't need to define it in every
function.
Add "while(1);" loops at the end of functions that reset the board, so that
execution doesn't continue while the reset is in progress.
Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where
appropriate.
Replace ulong/uint with their spelled-out equivalents. Remove unnecessary
typecasts, changing the types of some variables if necessary.
Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make
it easier for specific boards to support variations in the PIXIS registers
sets. No current boards appears to need this feature.
Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD.
Apparently, "pixis_reset altbank" has never worked on this board.

If the PCI controller wasn't configured or enabled delete from the
device tree (include its alias).
For the case that we didn't even configure u-boot with knowledge of
the controller we can use the fact that the pci_controller pointer
is NULL to delete the node in the device tree. We determine that
a controller was not setup (because of HW config) based on the fact
that cfg_addr wasn't setup.

If someone uses the FDPIC toolchain to compile U-Boot, make sure the
linker knows to use the normal ABI target rather than the FDPIC one.
This wasn't needed with older toolchains, but when we fixed the linker
such that the default target changed based on tuple, this broke.

Previous code was failing when reading back the timer less than
400us after resetting it. This lead nand operations to incorrectly
timeout any now and then. Moreover, writing the load register isn't
immediately reflected in the value register. We must wait for a clock
edge, so read_timer now waits for the value to change at least once,
otherwise nand operation would timeout anyways (though less frequently).

When the timestamp is incremented via interrupt and the interrupt
period is greater than 1 msec, successive calls to get_timer() can
produce inaccurate timing since the interrupts are asynchronous
to the timing loop. For example, with an interrupt period of 10 msec
two successive calls to get_timer() could indicate an elapsed time
of 10 msec after only several hundred usecs -- depending on when
the next interrupt actually occurs. This behavior can cause
reliability issues with components such as CFI and NAND.
This can be remedied by calling reset_timer() prior to establishing
the base timestamp with get_timer(0), provided reset_timer()
resets the hardware timer (rather than simply resetting only the
timestamp). This has the effect of synchronizing the interrupts
(and the advance of the timestamp) with the timing loop.
