bb25aca134 arm: socfpga: Convert reset manager from struct to defines
Convert reset manager for Gen5, Arria 10 and Stratix 10 from struct
to defines.

Change to get reset manager base address from DT node instead of using
#define.

spl_early_init() initializes the DT setup. So, move spl_early_init() to
beginning of function and before get base address from DT.

430b42f76a arm: socfpga: remove re-added ad-hoc reset code
commit c5de2b7eae ("arm: socfpga: implement proper peripheral reset")
has removed the call to 'reset_deassert_peripherals_handoff()' from
socfpga gen5 SPL since the reset driver now handles resets. However,
commit c1d4b464c8 ("ARM: socfpga: Disable bridges in SPL unless booting from FPGA")
has re-added this ad-hoc reset code, so that all peripherals were now
again enabled instead of letting the drivers enable them by request.

While at it, remove this function for gen5 as it should not be used.

Fixes: commit c1d4b464c8 ("ARM: socfpga: Disable bridges in SPL unless booting from FPGA")

8df653c325 ARM: socfpga: Factor out handoff register configuration
Factor out the code for programming preloader handoff register values,
the ISWGRP Handoff 0 and 1. These registers later control which bridges
are enabled by the "bridge" command on Gen5 devices.

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.
