As part of the main conversion a few files were missed. These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict. This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

Mask HRESET_B after cleared the the RCW_SRC, because in the workaround
we override the RCW_SRC and if HRESET_B is issued after the override
then SoC cannot find valid RCW as the RCW_SRC was overwritten and
result in hang. So we need to mask HRESET_B in case user asserts it,
and the PORESET_B should be asserted which leads to resampling of
cfg_rcw_src pins and loading of correct RCW_SRC.

JR3 was getting removed from device tree only if random number
generation was successful. However, if SEC firmware is present,
JR3 should be removed from device tree node irrespective of the
random seed generation as SEC firmware reserves it for it's use.
Not removing it in case of random number generation failure causes
the kernel to crash.
Random number generation was being called twice. This is not
required. If SEC firmware is running, SIP call can be made to the SEC
firmware to get the random number. This call itself would return
failure if function is not supported. Duplicate calling of random
number generation function has been removed.

find_next_zero_bit() incorrectly handles cases when:
- total bitmap size < 32
- rest of bits to process
static inline int find_next_zero_bit(void *addr, int size, int offset)
{
unsigned long *p = ((unsigned long *)addr) + (offset >> 5);
unsigned long result = offset & ~31UL;
unsigned long tmp;

result += 32;
size -= 32;
}

if (!size)
return result;
tmp = *p;
found_first:
[3] tmp |= ~0UL >> size;
^^^ algo can reach above line from from points:
[1] offset > 0 and size < 32, tmp[offset-1..0] bits set to 1
[2] size < 32 - rest of bits to process
in both cases bits to search are tmp[size-1..0], but line [3] will simply
set all tmp[31-size..0] bits to 1 and ffz(tmp) below will fail.
example: bitmap size = 16, offset = 0, bitmap is empty.
code will go through the point [2], tmp = 0x0
after line [3] => tmp = 0xFFFF and ffz(tmp) will return 16.
found_middle:
return result + ffz(tmp);
}
Fix it by correctly seting tmp[31..size] bits to 1 in the above case [3].

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.

Thumb-2 technology for optimum code density and processing throughput.
Except for MPU(Memory Protection Unit) and few CP15 registers, most of the
features are compatible with v7 architecture. So,reuse the same armv7

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.
As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members. There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".
As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.
Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

Save and use the 3rd parameter of PSCI CPU_ON request: context_id.
The context_id parameter is only meaningful to the caller.
U-Boot PSCI preserves a copy of the value passed in this parameter.
Following wakeup from a powerdown state, U-BOOT PSCI places
this value in R0 when it first enters the OS.
NB: this context id is not (yet?) used by Linux but it is mandatory
to be PSCI compliant.
update armv7 psci functions:
- psci_save_target_pc(): keep for backward compatibility with
current platform (only save PC and force context id to 0)
=> should be removed when all platform migrate to the new API
- psci_save(): new API to use by ARMv7 platform with PSCI,
save pc (= entry_point_address) and context_id

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 multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.
