Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:

expression argvalue;
@@
- reset_cpu(argvalue)

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

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.

OMAP5432 did go into production with AVS class0 registers which were
mutually exclusive from AVS Class 1.5 registers.
Most OMAP5-uEVM boards use the pre-production Class1.5 which has
production efuse registers set to 0. However on production devices,
these are set to valid data.
scale_vcore logic is already smart enough to detect this and use the
"Nominal voltage" on devices that do not have efuse registers populated.
On a test production device populated as follows:
MPU OPP_NOM:
=> md.l 0x04A0021C4 1
4a0021c4: 03a003e9 ....
(0x3e9 = 1.01v) vs nom voltage of 1.06v
MPU OPP_HIGH:
=> md.l 0x04A0021C8 1
4a0021c8: 03400485 ..@.
MM OPP_NOM:
=> md.l 0x04A0021A4 1
4a0021a4: 038003d4 ....
(0x3d4 = 980mV) vs nom voltage of 1.025v
MM OPP_OD:
=> md.l 0x04A0021A8 1
4a0021a8: 03600403 ..`.
CORE OPP_NOM:
=> md.l 0x04A0021D8 1
4a0021d8: 000003cf ....
(0x3cf = 975mV) vs nom voltage of 1.040v
Since the efuse values are'nt currently used, we do not regress on
existing pre-production samples (they continue to use nominal voltage).
But on boards that do have production samples populated, we can leverage
the optimal voltages necessary for proper operation.
Tested on:
a) 720-2644-001 OMAP5UEVM with production sample.
b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.

This patch adds support to update the device-tree blob to adjust the
DSP and IVA DPLL clocks pertinent to the selected OPP choice, with
the default being OPP_NOM. The voltage settings are done in u-boot,
but the actual clock configuration itself is done in kernel because
of the following reasons:
1. SoC definition constraints us to NOT to do dynamic voltage
scaling ever after the initial avs0 setting in bootloader
- so the voltage must be set in bootloader.
2. The voltage level must be set even if the IP blocks like
GPU/DSP are unused.
3. The IVA, GPU and DSP DPLLs are not essential for u-boot functionality,
and similar DPLL clock configuration code has been cleaned up in
v2014.10 u-boot release. See commit, 02c41535b6 ("ARM: OMAP4/5:
Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL").
The non-essential DPLLs are configured within the kernel during

needs.

This is done using Kconfig macros that can be set in a defconfig

to be configured/set to a corresponding voltage value depending
on the OPP selection choice.
The Kconfig choices have been added for MPU, DSPEVE, IVA and GPU
voltage domains, with the MPU domain restricted to OPP_NOM. The
OPP_OD and OPP_HIGH options will be added when the support for
configuring the MPU clock frequency is added. The clock
configuration for other voltage domains is out of scope in
u-boot code.
The CORE voltage domain does not have separate voltage values
and efuse register offset at different OPPs, while the MPU
voltage domain only has different efuse register offsets for
different OPPs, but uses the same voltage value. Any different
choices of OPPs for voltage domains on common ganged-rails
is automatically taken care to select the corresponding
highest OPP voltage value.
