ce82ff0538 FPU POST: fix warnings when building with 2.18 binutils
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.

a525145d81 POST: switch CFG_POST_OCM with CFG_POST_CODEC (workaround)
Switch the OCM testid with the codec one. The reason is that current
implementation requires the POST_ROM testid to fit into lower 16
bits, and the codec test will never run with POST_ROM hopefully.

Added OCM test to POST layer. This version runs before all other tests
but doesn't yet interrupt post sequence on failure.

b428f6a8c6 The patch introduces the CRITICAL feature of POST tests. If the test marked as POST_CRITICAL fails then the alternative, post_critical, boot-command is used. If this command is not defined then U-Boot enters into interactive mode.
