Some boards have fallen out of sync by defining CONFIG_ENV_IS_EMBEDDED
manually. While it is useful to have this available to the build system,
let's do it automatically rather than forcing people to opt into it.

Shove a lot of the HOSTCC and related #ifdef checking crap into the new
compiler.h header so that we can keep all other headers nice and clean.
Also introduce custom uswap functions so we don't have to rely on the non
standard implementations that a host may (or may not in the case of OS X)
provide. This allows mkimage to finally build cleanly on an OS X system.

Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.
IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)
This driver support mflash IO mode.
Followings are brief descriptions about IO mode.
1. IO mode based on ATA protocol and uses some custom command. (read
confirm, write confirm)
2. IO mode uses SRAM bus interface.

common/env_common.c (default_env): new function that resets the environment to
the default value
common/env_common.c (env_relocate): use default_env instead of own copy
common/env_nand.c (env_relocate_spec): use default_env instead of own copy
include/environment.h: added default_env prototype

The envcrc.c does sizeof(unsigned long) when calculating the crc, but
this is done with the build toolchain instead of the target tool
chain, so if the build is a 64bit system but the target is 32bits,
the size will obviously be wrong. This converts all unsigned long
stuff related to crc32 to uint32_t types. Compile tested only: output
of ./tools/envcrc when run on a 32bit build system matches that of a
64bit build system.

The current NAND Bootloader setup forces the environment
variables to be in line with the bootloader. This change
enables the configuration to be made in the board include
file instead so that it can be individually enabled.
