04ce5427bd spl: Weed out CONFIG_SYS_TEXT_BASE usage
The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location
is available and can be corrupted by loading ie. uImage or fitImage
headers there. Sometimes it could be beneficial to load the headers
elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we
still want to parse the image headers in some local onchip memory to
ie. extract firmware from that image.

Add the possibility to override the location where the headers get
loaded by introducing new function, spl_get_load_buffer() which takes
two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the
data that are to be loaded there -- and returns a valid buffer address
or hangs the system. The default behavior is the same as before, add
the offset to CONFIG_SYS_TEXT_BASE and return that address. User can
override the weak spl_get_load_buffer() function though.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.
