While debugging one ill behaving USB device I found two bugs in USB
storage probe.

usb_stor_get_info() returns -1 (error), 0 (skip) or 1 (ok). First part
of this patch fixes error case.

Second part fixes usb_inquiry()'s retry counter handling. Original code
had retry = -1 on error case, not retry = 0 as checked in the next line.

Here's another USB storage patch. Currently U-Boot handles storage
devices #0 - #4 as valid devices, even if there is none connected. This
patch fixes usb_stor_get_dev() to check detected device count instead
of MAX-define.

This is very important for ill behaving devices. usb_dev_desc[] can be
partially initialized if device probe fails.

After fixing get_dev() it was easy to fix "usb part" etc commands.
Previously it outputed "Unknown partition table" five times, now it's
"no USB devices available".

Commit b416191a (Fix EHCI port reset.) didn't
move the code that checked for successful clearing of the port reset bit from
ehci_submit_root(), relying on wait_ms() call instead. The mentioned code also
erroneously reported port reset state when the reset was already completed.

USB devices on the 2nd port are not detected and I get the following message:

The request port(1) is not configured

That's with default CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS value of 2. 'req->index'
is 1-based, so the comparison in ehci_submit_root() can't be correct.

This patch adds reset_timer() before the flash status check
waiting loop.

Since the timer is basically running asynchronous to the cfi
code, it is possible to call get_timer(0), then only a few
_SYSCLK_ cycles later an interrupt is generated. This causes
timeout even though much less time has elapsed. So the timer
period registers should be reset before get_timer(0) is
called.

There is similar usage in nand_base.c.

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.

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).
