Support bootdelay=0 in abortboot for the CONFIG_AUTOBOOT_KEYED case
similar to the CONFIG_ZERO_BOOTDELAY_CHECK support for the
!CONFIG_AUTOBOOT_KEYED case.

Do this by reversing the loop so we do at least one iteration before
checking for timeout.

Generic i386 reset - #define made redundant by weak function

CONFIG_SC520 is now used for conditional compile

Reset function specific to AMD SC520 microcontroller - Is more of a
'hard reset' that the triple fault.

Requires CONFIG_SYS_RESET_SC520 to be defined in config

I would have liked to add this to a new file (cpu/i386/sc520/reset.c)
but ld requires that a object file in a library arhive MUST contain
at least one function which does not override a weak function (and is
called from outside the object file) in order for that object file to
be extracted from the archive. This would be the only function on the
new file, and hence, will never get linked in.

Moved from interrupts.c to cpu.c and made into a weak function to
allow vendor specific override

Vendor specific CPU reset (like the AMD SC520 MMCR reset) can now be
added to the vendor specific code without the need to remember to
#undef usage of the generic method and if you forget to include your
custom reset method, you will always get the default.

Add a do_div() wrapper, lldiv(). The new inline function doesn't modify
the dividend and returns the result of division, so it is useful
in complex expressions, i.e. "return(a/b)" -> "return(lldiv(a,b))"

Error with CONFIG_NAND_LEGACY in common/cmd_nand.c:
With current code "nand read.jffs2s" (read and skip bad blocks) is always interpreted as
"nand read.jffs2" (read and fill bad blocks with 0xff). This is because ".jffs2" is
tested before ".jffs2s" and only the first two characters are compared.

Correction:
Test for ".jffs2s" first and compare the first 7 characters.

This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define

 #define NAND_MAX_CHIPS          CONFIG_SYS_MAX_NAND_DEVICE

but that's bogus and did not work anyhow.

We load the secondary stage u-boot image from NAND to
system memory by nand_load, but we did not flush d-cache
to memory, nor invalidate i-cache before we jump to RAM.
When the system has cache enabled and the TLB/page attribute
of system memory is cacheable, it will cause issues.

- 83xx family is using the d-cache lock, so all of d-cache
  access is cache-inhibited. so you can't see the issue.
- 85xx family is using d-cache, i-cache enable, partial
  cache lock. you will see the issue.

This patch fixes the cache issue.

Rather than putting the function prototype for board_nand_init() in the one
place where it gets called, put it into nand.h so that every place that also
defines it gets the prototype.  Otherwise, errors can go silently unnoticed
such as using the wrong return value (void rather than int) when defining
the function.
