The inline assembly functions in mon.c assume that the caller will
check for the return value in r0 according to regular ARM calling
conventions.

However, this assumption breaks down if the compiler inlines the
functions. The caller is then under no obligation to use r0 for the
result.

To fix this disconnect, we must explicitly move the return value
from the smc/bl call to the variable that the function returns.

The load address of ramdisk, rdaddr is 0x88080000 and fit_loadaddr
is defined as 0x88000000. This leaves only 512Kbytes for the
fit image. When the FIT images are larger than this, it will
overwite the ramdisk and cause the boot to fail.

For eg, The K2 HS fit images are a few MB and end up overwriting
the ramdsk. This patch moves the fit_loadaddr to 0x87000000,
leaving a 16MB window for the fit image. This memory can be
reclaimed once the kernel starts running.

On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.

To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.

On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.

As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.

For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

   CONFIG_ENV_IS_NOWHERE

In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.

In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.

There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with

   ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC

And then manual updates.  This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.
