[trini: Re-migrate]

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This converts the following to Kconfig:
CONFIG_ENV_IS_IN_MMC
CONFIG_ENV_IS_IN_NAND
CONFIG_ENV_IS_IN_UBI
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.

There are a few options which use lower case. We should use upper case for
all CONFIG options.

This patch enables flash protection(lock/unlock) for CFI devices.
This is necessary because the Parallel NOR flash connected on the spear
boards, M28W64, can be locked/unlocked on a sector basis. Moreover, all its
sectors are in locked state at reset and these have to be unlocked explicitly
before being erased or written.

This patch modifies the default environment variables as:
1. Default bootargs:
- console=ttyAMA0,115200
- For environment present in NOR flash
root=/dev/mtdblock3
- For environment present in NAND flash
root=/dev/mtdblock7
- Removes "mem=" option
2. Introduces CONFIG_EXTRA_ENV_USBTTY as default usbtty env var even when usbtty
is not selected
3. Add default definitions for nfsboot and ramboot
4. Add a new default environment variable(CONFIG_EXTRA_ENV_UNLOCK) for SPEAr310
and SPEAr320
Signifacance of CONFIG_EXTRA_ENV_USBTTY:
This environment variable is important for flashing utility to work. So if
somebody accidently erases the env sector then also this variable must be
preserved so that flashing utility functions properly.
Signifacance of CONFIG_EXTRA_ENV_UNLOCK:
This env variable is read by the cfi driver to unlock all flash sectors. This
is necessary because the Parallel NOR flash connected on the spear310 and
spear320 boards, M28W64, has all its sectors in locked state at reset and these
have to be unlocked explicitly before being erased or written.

This patch adds options for all the below mentioned configurations and
subsequently renames the include/configs/spearxxx.h files to spear3xx_evb.h,
spear6xx_evb.h etc to depict evaluation board configuration.
SPEAr3xx and SPEAr6xx boards can be compiled in following configurations
1. Environment placed in NAND
2. Console on usb device
3. Console on usb device with environment placed in NAND
4. SPEAr310 and SPEAr320 support environment variables in parallel
NOR flash.
