Include this header to get access to link symbols, which are otherwise
removed.

Signed-off-by: Simon Glass <sjg@chromium.org>

We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.

Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.

One change is needed in arch/avr32/lib/board.c to make this conversion
work.

Note this is a tree-wide change affecting multiple architectures.

At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.

Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

This patch corrects the following issues

1) Write the correct M/T Stop value to I2CSTAT after i2c write.
   According to the spec, after finish the data transmission, we should
   write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of
   a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA).
2) Not split the write to I2CSTAT into 2 steps in i2c read.
   According to the spec, we should write the combined M/R Start value to
   I2CSTAT after setting the slave address to I2CDS
3) Fix the mistake of making an equality check to an assignment.
   In the case of I2C write with the zero-length address, while tranfering the
   data, it should be an equality check (==) instead of an assignment (=).

Because the code that handles bootdelay is compiled in conditionally
based on the default value, you are restricted in the default,
regardless of what you want the runtime options to be.

Change the source to always check if any default is given so that other
values can be selected and used at runtime.

The "env ask" traditionally uses a somewhat awkward syntax:

	env ask name [message ...] [size]

So far, when a mesage was given, you always also had to enter a size.
If you forgot to do that, the command would terminate without any
indication of the problem.

To avoid incompatible changes of the interface, we now check the last
argument if it can be converted into a decimal number.  If this is the
case, we assume it is a size; otherwise we treat it as part of the
message.

Also, add a space after the message fore easier reading,
and clean up help mesage.

ps on BSD hosts (like OS X) do not provide the --no-headers switch nor
understand the AIX format descriptions. Unfortunately there seems no solution to
get the PIDs of children in a platfrom independent manner.
Therefore detect the OS and decide upon that which way to go.

This patch makes the MAKEALL script cleanly stoppable on bare OS X when using
the parallel builds of targets.

Additionally this patch removes double call to grep by a single call to sed for
GNU style child PID detection.

The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses.  If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users?  As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.

As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h;  we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.
