This patch fixes a bug (?) introduced after inclusion of the new
JFFS2 code.
When not using CONFIG_JFFS2_CMDLINE, the code in cmd_jffs2.c doesn't
fill in part->sector_size (keeping it as 0), but a correct value is
needed by the code in jffs2_1pass.c. This causes all JFFS2 accesses
to be in the same place of the memory, what obviously means
impossibility to use the JFFS2 partition.
This problem is fixed in this patch by including sector size
calculation in non-CONFIG_JFFS2_CMDLINE mtdparts_init variant.

This patch adds a #define to optionally change the behaviour of
i2c_read() in soft_i2c.c to send an I2C repeated start instead of a
stop-start between sending the device address pointer write and
reading back the data. The current behaviour is retained as the
default.
While most devices will work either way, I have a smart battery(*)
that requires repeated start, and someone at some point found a
device that required a stop-start.

U-Boot's gunzip() function does not handle the return code
of zlib's inflate() function correctly. gunzip() is implemented
to uncompress all input data in one run. So the correct return
code for the good case is Z_STREAM_END. In case of insufficient
output buffer memory inflate returns Z_OK. For gunzip() this
is an error.
It also makes sense to me to call inflateEnd() also in case
of an error.

Added flash_fixup_stm to fix geometry reversal on STMicro M29W320ET flash chip.
Modeled after flash_fixup_amd, this patch handles the geometry reversal

Since I cannot test all STM's chips, the detection is implemented as

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.

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.

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

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.

Vendor specific CPU reset (like the AMD SC520 MMCR reset) can now be

#undef usage of the generic method and if you forget to include your
custom reset method, you will always get the default.
