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.

Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk
This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.

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.

Read-to-read/Write-to-write turnaround for same chip select
of DDR3 memory, BL/2+2 cycles is enough for them at BC4 and
OTF case, BL/2 cycles is enough for fixed BL8.
Cutting down the turnaround from BL/2+4 to BL/2+2 or BL/2
will improve the memory performance.

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).

Nand Flash, Ethernet, other features might need to configure the

address(0x70000000 - 0x7fffffff) exists at only S3C64XX cpu, so they

The get_pll_clk(int) API returns the PLL frequency based on
the (int) argument which is defined locally in clock.c
Moving that #define to common header file (clk.h) would
be helpful when using the API from other files.

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.

After determining how much DDR is actually in the system, set DBAT0 and
IBAT0 accordingly. This ensures that the CPU won't attempt to access
(via speculation) addresses outside of actual memory.
On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB
and kept that way. If the system has less than 2GB of memory (typical for
an MPC8610 HPCD), the CPU may attempt to access this memory during
speculation. The zlib code is notorious for generating such memory reads,
and indeed on the MPC8610, uncompressing the Linux kernel causes a machine
check (without this patch).
Currently we are limited to power of two sized DDR since we only use a
single bat. If a non-power of two size is used that is less than
CONFIG_MAX_MEM_MAPPED u-boot will crash.

Use the same code between primary and secondary cores to init the
L1 cache. We were not enabling cache parity on the secondary cores.
Also, reworked the L1 cache init code to match the e500mc L2 init code
that first invalidates the cache and locks. Than enables the cache and
makes sure its enabled before continuing.

This patch fixes a problem introduced with patch eb5eb2b0
[ppc4xx: Cleanup PPC4xx I2C infrastructure]. We need to assign the I2C
base address to the "i2c" pointer inside of the controller loop.
Otherwise controller 0 is initialized multiple times instead of
initializing each I2C controller sequentially.
Tested on Katmai.
