26fb85f4ab socfpga: fix include guard in misc.h (arch vs. global)
The file arch/arm/mach-socfpga/include/mach/misc.h used the same include
guard as the global include/misc.h.

Fix this by giving the arch file an arch prefix.

48ec73453a arm: sofcpga: s10: remove unused ad-hoc reset code
The stratix 10 reset manager ad-hoc code in arch/arm contains an unused
function 'reset_deassert_peripherals_handoff' that has been added from
the beginning. As this is probably a result of copying the gen5 reset
manager and this function has never been used, remove it.

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.

29873c74f3 arm: socfpga: move gen5 SDR driver to DM
To clean up reset handling for socfpga gen5, port the DDR driver to DM
using UCLASS_RAM and implement proper reset handling.

This gets us rid of one ad-hoc call to socfpga_per_reset().

The gen5 driver is implemented in 2 distinct files. One of it (containing
the calibration training) is not touched much and is kept at using
hard coded addresses since the code grows even more otherwise.

SPL is changed from calling hard into the DDR driver code to just
probing UCLASS_RESET and UCLASS_RAM. It is happy after finding a RAM
driver after that.

0b8f6378cb ARM: socfpga: Reorder Arria10 SPL
The Arria10 SPL is a complete mess of calls to functions which are
called in the wrong context and it is surprise it works at all. This
patch tries to clean that mess up by shuffling the function calls
around and moving the calls into the correct context. Due to the
delicate nature of the reordering, this is done in one huge patch.

The following changes happen in this patch:
- Security policy init and NIC301 happens first in board_init_f()
- The clock init happens very early in board_init_f() in SPL only
- arch_early_init_r() only registers the FPGA, just like on Gen5
- arch_early_init_r() is never called from any _f() function
- Dedicated FPGA pins are inited in board_init_f() as on Gen5

34fc2a6edf ARM: socfpga: Add boot trampoline for Arria10
The Arria10 uses slightly different boot image header than the Gen5 SoCs,
in particular the header itself contains an offset from the start of the
header to which the Arria10 jumps. This offset must not be negative, yet
the header is placed at offset 0x40 of the bootable binary. Therefore, to
jump into U-Boot, add a trampoline just past the Arria10 boot header and
point to this trampoline at fixed offset from the header generated using
the mkimage -T socfpgaimage_v1 . Note that it is not needed to jump back
to offset 0x0 of the image, it is possible to jump directly at the reset
label and save processing two instructions.

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.
