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.

The mpuclk register in the Altera group of the clock manager
divides the mpu_clk that is generated from the C0 output of the main

Without this patch, the default value of the register is 1, so the mpuclk

on the Arria5 socdk board, the MPU clock is only 525 MHz, and it should be
1.05 GHz.

beee6a3083 ARM: socfpga: Add boot0 hook to prevent SPL corruption
Valid Altera SoCFPGA preloader image must contain special data at
offsets 0x40, 0x44, 0x48 and valid instructions at address 0x4c or
0x50. These addresses are by default used by U-Boot's vector table
and a piece of reset handler, thus a valid preloader corrupts those
addresses slightly. While this works most of the time, this can and
does prevent the board from rebooting sometimes and triggering this
issue may even depend on compiler.

The problem is that when SoCFPGA performs warm reset, it checks the
addresses 0x40..0x4b in SRAM for a valid preloader signature and
header checksum. If those are found, it jumps to address 0x4c or
0x50 (this is unclear). These addresses are populated by the first
few instructions of arch/arm/cpu/armv7/start.S:

ffff0040 <data_abort>:
ffff0040:       ebfffffe        bl      ffff0040 <data_abort>

ffff0044 <reset>:
ffff0044:       ea000012        b       ffff0094 <save_boot_params>

ffff0048 <save_boot_params_ret>:
ffff0048:       e10f0000        mrs     r0, CPSR
ffff004c:       e200101f        and     r1, r0, #31
ffff0050:       e331001a        teq     r1, #26

Without this patch, the CPU will enter the code at 0xffff004c or
0xffff0050 , at which point the value of r0 and r1 registers is
undefined. Moreover, jumping directly to the preloader entry point
at address 0xffff0000 will also fail, because address 0xffff004.
is invalid and contains the preloader magic.

Add BOOT0 hook which reserves the area at offset 0x40..0x5f and
populates offset 0x50 with jump to the entry point. This way, the
preloader signature is stored in reserved space and can not corrupt
the SPL code.
