This patch adds support to load secure bitstreams(authenticated or
encrypted or both). As of now, this feature is added and tested only
for xilinx bitstreams and the secure bitstream was generated using
xilinx bootgen tool, but the command is defined in more generic way.
Command example to load authenticated and device key
encrypted bitstream is as follows
"fpga loads 0 100000 2000000 0 1"

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 drops the limit that fpga is only loaded from FIT images for Xilinx.
This is done by moving the 'partial' check from 'common/image.c' to
'drivers/fpga/xilinx.c' (the only driver supporting partial images yet)
and supplies a weak default implementation in 'drivers/fpga/fpga.c'.

Clean up partial, full and compressed bitstream handling.
U-Boot supports full bitstream loading and partial
based on detection which is not 100% correct.

argument which stores bitstream type.

needed when building for non-Lattice devices, which results in build

The patch adds support to load a Lattice's bitstream
image (called VME file) into a Lattice FPGA. The code
containing the state machine delivered as part of
Lattice's ispVMtools is integrated.
The FPGA is programmed using the JTAG interface. The
board maintainer must provide accessors to drive the
JTAG signals TCK, TMS, TDI and to get the value of the
input signal TDO.
