The 440SPe Rev. A is quite old and newer 440SPe boards don't need support
for this CPU revision. Since removing support for this older version
simplifies the creation for newer U-Boot ports, this patch now enables
440SPe > Rev. A support by creating the CONFIG_440SPE_REVA define. By
defining this in the board config header, Rev. A will still be supported.
Otherwise (default for newer board ports), Rev. A will not be supported.

The latest changes increased the size of the alpr image a bit more.
Now it doesn't fit into the 256k reserved for it. This patch now removes
the commands "loads" and "loadb" which are not needed in the production
systems.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

The appropriate include/asm-$ARCH directory should already by symlinked
to include/asm so using the whole "asm-$ARCH" path is unnecessary.
This change should also allow us to move the include/asm-$ARCH
directories into their appropriate lib/$ARCH/ directories.

Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.

Previously, a specific file or directory could be compiled with custom
CFLAGS by adding a Makefile variable such as:
CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c>
or
CFLAGS_lib = <custom flags for lib directory>
This method breaks down once multiple files or directories share the
same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in
both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>.
This change allows finer grained control which we need once we move
lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this
change all lib/ directories would share the same custom CFLAGS.

The CPUDIR variable points to the location of a target's CPU directory.
Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for
more flexibility in the future. It lays the groundwork for reorganizing
U-Boot's directory structure to support a layout such as:
arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types)
arch/$ARCH/cpu/* (architecture with one CPU type)

gcc 3.4.6 previously reported the following error on many MIPS boards
which utilize UBI:

The current code is structured such that 'vol' will never be used when
it is NULL anyway, but gcc isn't smart enough to figure this out.

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 b416191a14 (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:

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.
