Yuri Tikhonov [Sat, 20 Dec 2008 11:54:21 +0000 (14:54 +0300)]
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.

NAND: Fix cache and memory inconsistency issue

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.
