SystemID information could be read through I2C1 from EEPROM
on LS1021ATWR board.
As LS1 is a little-endian processor, getting the version ID by
be32_to_cpu() is wrong. Fix it by using e.version directly.
This change will be compatible for both ARM and PowerPC.
As there is an errata that I2C1 could not work in SD boot,
reading EEPROM through I2C1 is disabled too in SD boot.

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

Since the Pfuze initializations are similar on various mx6 SABRE
boards. Factorize the initialization to a common function in file
board/freescale/common/pfuze.c. So that all SABRE boards BSP can
share the function.

According to AN3638, CRC of NXID v1 is at the end of the
256-byte I2C memory. The wrong CRC32 offset prevents Uboot
from reading system information from EEPROM. No NXID v0 is
being used on Freescale boards.

The return value has not been checked by its caller, until recent change
of using generic board architecture. The error of this function is not
critical enough to hang the system. Printing the warning message is enough
to catch user's attention. U-boot should continue to boot to give user
a chance to fix the EEPROM. Chaning the return value to 0 to avoid hanging
in the board_init_r().

On BSC9131, BSC9132, P1010 : For High Capacity SD Cards (> 2 GBytes), the
32-bit source address specifies the memory address in block address
format. Block length is fixed to 512 bytes as per the SD High Capacity
specification. So we need to convert the block address format
to byte address format to calculate the envaddr.
If there is no enough space for environment variables or envaddr
is larger than 4GiB, we relocate the envaddr to 0x400. The address
relocated is in the front of the first partition that is assigned
for sdboot only.
