f25c1755a7 rockchip: Fix rkimage format for SPL boot over USB
The 'rkimage' format used for booting rockchip boards over USB seems to
have been broken since commit 7bf274b9ca ("rockchip: mkimage: use
imagename to select spl hdr & spl size"). That commit adds an offset of
RK_SPL_HDR_START(=2048) to the location the 'RKxx' header is written
at. However the bootrom expects this header to be the first four bytes of
the image, not at offset 2048. This appears to have been a copy paste
error since the 'rksd' and 'rkspi' image types do require this offset.

Furthermore commit 111bcc4fb6 ("rockchip: mkimage: pad the header to
8-bytes (using a 'nop') for RK3399"), commit 3d54eabcaf ("rockchip:
spl: RK3399: use boot0 hook to create space for SPL magic") and
commit 3082775692 ("rockchip: mkimage: update rkimage to support
pre-padded payloads") changed the way the space for the 'RKxx' header is
allocated and written to the image without adjusting 'rkimage'.

This commit fixes those mistakes and makes it possible to load u-boot SPL
over USB once more.

(Tested on RK3399)

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.

253c60a557 rockchip: mkimage: remove placeholder functions from rkimage
The imagetool framework checks whether function pointer for the verify,
print and extract actions are available and will will handle their
absence appropriately.

This change removes the unnecessary functions and uses the driver
structure to convey available functionality to imagetool.  This is in
fact better than having verify just return 0 (which previously broke
dumpimage, as dumpimage assumed that we had handled the image and did
not continue to probe further).

cfbcdade76 rockchip: mkimage: Allow encoding of loader code in spl images
Rockchip SoCs allow the spl code to be rc4-encoded, not only the
image header, but only newer SoCs allow this encoding to be disabled.

The rk3188 is not part of those and requires its boot code to be
rc4-encoded with the regular key. So add the ability to do this
encoding via a setting on a per-soc basis when building spl images.

We need a correct name (rk3288, rk3036) so check this to avoid a crash
later.

7bf274b9ca rockchip: mkimage: use imagename to select spl hdr & spl size
Our chips may have different spl size and spl header, so
use imagename(passed by "mkimage -n") to select them now.

a131c1f442 rockchip: Add the rkimage format to mkimage
Rockchip SoCs require certain formats for code that they execute, The
simplest format is a 4-byte header at the start of a binary file. Add
support for this so that we can create images that the boot ROM understands.
