Disable L2 caches for Trats and Trats2 devices.
It turns out that for data downloading with thordown command L2 cache
disablement brings a significant speed improvement.
rootfs - 400 MiB:
- L2 cache enabled: 2.69 MiB/s
- L2 cache disabled: 5.56 MiB/s
Such improvement is possible due to reduction of the need to invalidate
redundant data, which resides in L2 cache.
Since the sent USB request size at once is 512B (L1 - 32 KiB in total) -
one can be quite confident that it is already available in L1 and L2 can
be disabled.

This patch adds extra dfu_alt_info entries to support storing the whole BOOT
, DATA and UMS partitions.
This allows upgrade of uImage and device tree blob (dtb) files at once.
Now it is also possible to store ext4 rootfs prepared with well established
linux tools (like mkfs.ext4).

Change the default environment to use zImage instead of uImage, this
requires changes to the default environment to load a file named
zImage instead of uImage, and to use the 'bootz' command instead of
'bootm' when booting the kernel.
The zImage works for FSL Linux's kernel fork versions 3.0.35, 3.10.9,
and 3.10.17; this also works fine for mainline kernels.

For standalone images, bootm had a special case where the OS boot function
was NULL but did actually exist. It was just called manually.
This was removed by commit 35fc84fa which checks for the non-existence of
this function before the special case is examined.
There is no obvious reason why standalone is handled with a special case.
Adjust the code so that standalone has a normal OS boot function. We still
need a special case for when the function returns, but at least we can
avoid the main problem.
This is intended to fix the reported:
ERROR: booting os 'U-Boot' (17) is not supported

Issues:
- reading i2c data by passing u16 pointer causes errors in read data.
- max17042 status register fields have not only Power On Reset meaning
so using proper mask is required.
Changes:
- read i2c data to type u32 instead of u16 - avoids buffer overflow
- compare FG status register using mask not just one bit value
- add checking return value to functions fg read/write
- add model lock and model check count
- add debug msg

Access the OneNAND 1KiB window on the VPAC270 as an SRAM instead of accessing

The OneNAND SPL used on PXA is slightly obscure. Due to the OneNAND limitation,
where we have only the first 1KiB of the OneNAND available upon power-up as a
memory-mapped area, from which the CPU starts executing, we place only the most
essential code into this first 1KiB . This code copies the rest of the SPL into
SRAM and jumps to it. This code is stored in section .text.0 .
The rest of the SPL is stored in section .text.1 . When running the OBJCOPY on
the SPL, it will preserve only .text section, but the .text.0 and .text.1 are
stripped away from the result, thus making the SPL binary empty. The patch adds
additional -j parameters to the OBJCOPY for PXA during the SPL build, which will
preserve the .text.0 and .text.1 sections.
Moreover, this patch also adds missing functions into the .text.0 section, since
otherwise the PXA270 with 1KiB-window OneNAND won't be able to boot.
