The standalone example does not have get_timer() defined, so we cannot
rely on it being available.
Move the timer function into boootstage.c to avoid this problem.
This corrects a build breakage for the standalone example on some boards.

This reverts commit 295d3942b806552503243f5cfb36aec6f1b5a9bf.
It turns that this really doesn't work very nicely. Instead we should
have a pre-console panic function so that we know that further execution
is impossible and we don't need to worry about trampling on UARTs, etc.

Define timer_get_boot_us() which returns the number of microseconds
since boot. If undefined then we use get_timer() * 1000.
We can fit this in a 32-bit register which keeps everyone happy on
the efficiency side. It will wrap around after about an hour. If we
are still looking at it after an hour then we had better not be
timing the boot.

At present boot_stage_progress() is called with various magic numbers. The
new bootstage.h header will be used to turn these into symbolic names
throughout the code.
The intent is not that these numbers are passed to Linux. In fact by using
an enum to track them we should eventually be able to remove the explict
numbers and just have the stages count up from 0.

Boards can select either the 'built-in' parser or the hush parser. We
should not call builtin_run_command() if we are using the hush parser.
We use run_command() instead, since it knows how to call the correct
parser.

The current run_command() is only one of the parsing options - the other
is hush. We should not call run_command() when the hush parser is being
used. So we rename this function to better explain its purpose.

This patch adds support for console output before the console is inited.
The main purpose of this is to deal with a very early panic() which would
otherwise cause a silent hang.
A new board_pre_console_putc() function is added to the board API. If
provided by the board it will be called in the event of console output
before the console is ready. This function should turn on all UARTs and
spray the character out if it possibly can.
The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option.

This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's
own use and is not necessarily the same one as is passed to the kernel.
The device tree compiler output should be placed in the $(obj)
rooted tree. Since $(OBJCOPY) insists on adding the path to the
generated symbol names, to ensure consistency it should be
invoked from the directory where the .dtb file is located and
given the input file name without the path.
This commit contains my entry for the ugliest Makefile / shell interaction
competition.

ARCH_DMA_MINALIGN will be used to allocate DMA buffers that are
aligned correctly. In all current cases this means that the DMA
buffer will be aligned to at least the L1 data cache line size of
the configured architecture. If the board configuration file
does not specify the architecture L1 data cache line size then the
maximum line size of the architecture is used to align DMA buffers.

Unified DDR driver is maintained for better performance, robustness and bug
fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of
overall improvement. It requires changes for board files to customize
platform-dependent parameters.
To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx
in the header file. No more boards will be accepted without such definition.
Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1
and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined.
This is useful when a condition is an error but a board reset is unlikely
to fix it, so it is better to soldier on in hope. Assertion failures should
be caught during development/test.
It turns out that assert() is defined separately in a few places in U-Boot
with various meanings. This patch cleans up some of these.
Build errors exposed by this change (and defining DEBUG) are also fixed in
this patch.

Currently when you call ROUND with a value that is already a
multiple of the second parameter it will return a value that is
one multiple larger, instead of returning the value passed in.
There are only two types of usage of ROUND currently, one in
various config files to round CONFIG_SYS_MALLOC_LEN to a multiple
of 4096 bytes. The other in cmd_sf.c where the incorrect behavior
of ROUND is worked around be subtracting one from the length argument
before passing it to ROUND.
This patch fixes ROUND and removes the workaround from cmd_sf. It
also results in all of the malloc pools that use ROUND to compute
their size shrinking by 4KB.

- Add a framework for layered cache maintenance
- separate out SOC specific outer cache maintenance from
maintenance of caches known to CPU
- Add generic ARMv7 cache maintenance operations that affect all
caches known to ARMv7 CPUs. For instance in Cortex-A8 these
opertions will affect both L1 and L2 caches. In Cortex-A9
these will affect only L1 cache
- D-cache operations supported:
- Invalidate entire D-cache
- Invalidate D-cache range
- Flush(clean & invalidate) entire D-cache
- Flush D-cache range
- I-cache operations supported:
- Invalidate entire I-cache
- Add maintenance functions for TLB, branch predictor array etc.
- Enable -march=armv7-a so that armv7 assembly instructions can be
used
