- CONFIG_ENV_EEPROM_IS_ON_I2C
  define this, if you have I2C and SPI activated, and your
  EEPROM, which holds the environment, is on the I2C bus.

- CONFIG_I2C_ENV_EEPROM_BUS
  if you have an Environment on an EEPROM reached over
  I2C muxes, you can now define, how to reach this
  EEPROM.

Current code uses the second argument to bootm for standalone images to
override the load address specified in the image instead of passing all
parameters as is to the application.  This behaviour is not documented
and not in line with how the go command works for standalone applications,
so we simply drop it.

In case we boot an image marked as 'standalone' and 'linux', the current
code erroneously tried to load a ramdisk.

Convert the funcs to do the conversion inline so that we can do the copy
all at once with memcpy.  This let's us push out an weird arch-specific
issue with accessing different regions of memory to the memcpy function
like the MMRs on Blackfin systems, and it should be a bit faster.

There are boards out there that do not have network support in
U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This
makes it desirable to be able to port network configuration (like
the IP address) to the Linux kernel.

We should not make the passing of the IP configuration to Linux
dependent on U-Boot features / settings.

For this, make getenv_IPaddr() global. This fixes build error

u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr'

on various architectures.
