At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).
Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.
Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

Now that all x86 boards have been converted to use DM, we can imply
these uclass drivers (DM_ETH, DM_RTC, DM_USB, DM_VIDEO) from the
top level.
Previously DM_GPIO, DM_KEYBOARD, DM_SERIAL, DM_SPI, DM_SPI_FLASH
are selected. Change to use 'imply' to allow them to be removed.
Note with this change, chromebook_link64 build fails:
common/built-in.o:(.data.env_htab+0xc): undefined reference to 'env_flags_validate'
lib/built-in.o: In function `hsearch_r':
lib/hashtable.c:380: undefined reference to 'env_callback_init'
lib/hashtable.c:382: undefined reference to 'env_flags_init'
make[1]: *** [spl/u-boot-spl] Error 1
CONFIG_SPL_ENV_SUPPORT is required for chromebook_link64 to build
again. This is just a workaround as it is not needed at all. See
commit bda40d5 "x86: qemu: Add a config for 64-bit U-Boot" for
the same issue seen on QEMU 64-bit target.

Add Intel Edison board which is using U-Boot.
The patch is based on work done by the following people (in alphabetical
order):
Aiden Park <aiden.park@intel.com>
Dukjoon Jeon <dukjoon.jeon@intel.com>
eric.park <eric.park@intel.com>
Fabien Chereau <fabien.chereau@intel.com>

Steve Sakoman <steve.sakoman@intel.com>
Vincent Tinelli <vincent.tinelli@intel.com>
In case we're building for Intel Edison, we must have 4096 bytes of
zeroes in the beginning on u-boot.bin. This is done in
board/intel/edison/config.mk.
First run sets hardware_id environment variable which is read from
System Controller Unit (SCU).
Serial number (serial# environment variable) is generated based on eMMC
CID.
MAC address on USB network interface is unique to the board but kept the
same all over the time.
Set mac address from U-Boot using following scheme:
OUI = 02:00:86
next 3 bytes of MAC address set from eMMC serial number
This allows to have a unique mac address across reboot and flashing.
