Add workaround for the following ARM errata: 743622 and 751472.
The motivation for this change is the following kernel commit 62e4d357a
(ARM: 7609/1: disable errata work-arounds which access
secure registers), which removes the errata from multiplatform kernel.
Since imx has been converted to multiplatform in the kernel, we need to apply
such workarounds into the bootloader.
Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel.
Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad"
document available at: cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf

In order to mx53 ROM to properly load the U-boot image, its header size should
be multiple of 512 bytes.
This issue was observed with gcc 4.6.2/4.7.3, which caused data aborts:

,and this patch fixes it.
Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."

commit c73368150 (pmic: Extend PMIC framework to support multiple instances
of PMIC devices) introduced an extra 'retval' variable, but this is not
necessary since we have already the variable 'ret' in place.
So use 'ret' to store the return values from the pmic related calls and remove
'retval'.

The on-board number of available usdhc devices is something board
specific. The patch moves CONFIG_SYS_FSL_USDHC_NUM out of
mx6qsabre_common.h and adds usdhc2 and usdhc4 support for mx6qsabresd
board.
To keep the default mmc device for environment same as before (usdhc3),

In e1000e driver, Rx descriptor queue is used such that hardware can add only
one descriptor at a time. So the WTHRESH granularity in RXDCTL should be set
to single descriptor. This would ensure that every time controller fills a Rx
descriptor, it is flushed to host memory. Earlier this granularity was in
cache line units i.e 2 descriptors. This leads to controller always waiting
for 2 descriptors before flushing them out. But since not more than one Rx BD
is actually available , the accumulation condition never gets hit.

- since commit 418396e212 nand write.raw
can take the number of page to be written as an argument. nand_update_full
is passing the size (in bytes) to nand write.raw. This value was previously
ignored but now breaks the write.
- this patch updates the default environment of these boards to provide a
pagecount instead of a size to nand write.raw.
- tested on a mx28evk with a 4k page NAND and on a custom board with a
2k page NAND.

Currently just validates variable types as decimal, hexidecimal,

If the entry is not found in the env .flags, then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

Move the read of the old value to inside the check function. In some
cases it can be avoided all together and at the least the code is only
called from one place.
Also name the function and the callback to more clearly describe what

Pass the ENTRY instead of just the name for direct access to the whole
data structure.
Pass an enum to the callback that specifies the operation being approved.
