arm_mem_barebox_image() is used to pick a suitable place where to
put the final image to. This is called from both the PBL uncompression
code and also from the final image. To make it work properly it is
crucial that it's called with the same arguments both times. Currently
it is called with the wrong image size from the PBL uncompression code.
The size passed to arm_mem_barebox_image() has to be the size of the
whole uncompressed image including the BSS segment size. The PBL code
calls it with the compressed image size instead and without the BSS
segment. This patch fixes this by reading the uncompressed image size
from the compressed binary (the uncompressed size is appended to the
end of the compressed binary by our compression wrappers). The size
of the BSS segment is unknown though by the PBL uncompression code,
so we introduce a maximum BSS size which is used instead.
The code before this patch worked by accident because the base address
of the final image was aligned down to a 1MiB boundary. The alignment
was sufficient already to make enough space. This breaks though when
the uncompressed image including BSS becomes bigger than 1MiB while
the compressed image is smaller.

The Makefile compression commands all append the size of the
uncompressed image. With CONFIG_IMAGE_COMPRESSION_NONE simply
'shipped' is used which does not append the size. Add and use
a special comp_copy function which adds the size. This helps
us to get the uncompressed image size in the startup code later.

Enable parent rate propagation for clk_gate2 to allow the
clock consumers to adjust their rates.
One effect of this is that the i.MX6 NAND controller now can adjust
its rate. It already called a clk_set_rate(rate, 96000000), but this
had no effect, so the clock stayed at reset default 24MHz resulting
in a rather slow timing. This became a problem when commit
"1daa3bc mtd: nand_mxs: Setup timing" introduced EDO timing mode for
faster NAND chips. EDO mode can only work properly for cycle times
< 30ns (at least that's specified in the ONFI spec). 1daa3bc resulted
in sporadic NAND read errors on some boards.

The second level page tables can only start at a 1MiB section boundary,
so instead of calling arm_create_pte() with the high vector address
(which is 0xffff0000, not 1MiB aligned) we have to call it with
0xfff00000 to correctly create a second level page table.
The old values broke SoCs which have peripherals in the upper 1MiB
area, like for example the Atmel AT91RM9200. On these Socs we correctly
created the vector page, but the pages around it did not have a 1:1
mapping anymore which led to unreachable peripherals.

The i.MX31 SPI interface was refered by freescale as spi_ver_0_4 in one
of their older vendor extended linux releases. spi_ver_0_4 differs only
in minor aspects to spi_ver_0_7 (i.MX35) which is already supported by
barebox.
Regarding barebox, the differences boil down to the location and length
of the CHIP SELECT and BIT COUNT/BURST LENGTH elements of CONREG. The
spi_ver_0_4 variant is limited to single word bursts with a maximum of
32 bits_per_word.
Add support for the i.MX31 SPI interface to the barebox spi_ver_0_7
implementation.
