Some images can be quite large, so add an option to compress the
image data with gzip in the U-Boot image. Then at runtime, the
board can decompress it with the normal zlib functions.

A couple of buffers in the fat code are declared as an array of bytes.
But it is then cast up to a structure with 16bit and 32bit members.
Since GCC assumes structure alignment here, we have to force the
buffers to be aligned according to the structure usage.

Higher spi flash layers expect to be given back a pointer that was
malloced so that it can free the result, but the lower layers return
a pointer that is in the middle of the malloced memory. Reorder the
members of the lower spi structures so that things work out.

When compile u-boot with the 2.18 binutils the following
warning messages for each object file in post/lib_ppc/fpu/ is
produced at the linking stage:

post/libpost.a(acc1.o) uses hard float, u-boot uses soft-float
...

This is because of the fact that, in general, the soft-float and
hard-float ABIs are incompatible; the 2.18 binutils do checking
of the Tag_GNU_Power_ABI_FP attribute of the files to be linked, and
produce the worning like above if these are not compatible.

The incompatibility of ABIs is concerned only the float values:
e.g. the soft-float ABI assumes the float argument passing in the
pair of rX registers, and the hard-float ABI assumes passing of
the float argument in the fX register. When we don't pass the float
arguments between the functions compiled with different floatness,
then such an application will work correctly.
This is the case for the FPU POST: u-boot (compiled with soft-float)
doesn't pass to (and doesn't get from) the FPU POST functions any
floats; there are no functions exported from the post/lib_ppc/fpu/
objects which would work with float parameters/returns too. So, we
can reassure the linker not to worry about the difference in ABI
attributes of linking files just by setting the 'soft-float'
attribute for the objects in post/lib_ppc/fpu. And this patch does
this.

Also, to avoid passing both soft- and hard-float options in CFLAGS
when compiling the files from post/lib_ppc/fpu (which is OK, but
looks rather dirty) this patch removes the soft-float string from
CFLAGS in post/lib_ppc/fpu/Makefile.

Initial support for the DS4510, a CPU supervisor with
integrated EEPROM, SRAM, and 4 programmable non-volatile
GPIO pins. The CONFIG_DS4510 define enables support
for the device while the CONFIG_CMD_DS4510 define
enables the ds4510 command. The additional
CONFIG_DS4510_INFO, CONFIG_DS4510_MEM, and
CONFIG_DS4510_RST defines add additional sub-commands
to the ds4510 command when defined.

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.

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.
