In order to support easier setup of test scenarios with fuel gauge
emulators, we should expose an API that can change internal emulator state.
Add a minimal fuel gauge emulator backend API for setting the charging
current and voltage with a sample implementation in the emul_sbs_gauge with
an associated driver test.

Currently, this section has LOAD flag which means that it's part of
image layout. Attempt to generate binary file with --gap-fill results in
creating a very big file, because LMA of the section is RAM address
(e.g. 0x20000000 for STM32F4) instead of FLASH (e.g. 0x8000000 for
STM32F4).
This problem doesn't appear when linking using GNU LD, because it
removes the section in garbage collect process. However, LLVM LLD
doesn't garbage collect sections that define used symbols, so the
section is present in final ELF image.
There is no need to load this section (it has 0 size), so we can safely
add NOLOAD attribute to the section.
Fixes: #57727

Until now, linker-tool-gcc.h was used when LLD linker was chosen.
This causes linking issues because for GNU LD we use ALIGN_WITH_INPUT
attribute which is not available in LLVM LLD.
When using GNU LD we have to use ALIGN_WITH_INPUT to make sure that the
difference between VMA and LMA remains the same between output sections
that have different memory regions for VMA and LMA (RAM and FLASH).
With ALIGN_WITH_INPUT it's safe to do the memcpy of sections
that needs to be copied from flash to RAM in one function call:
(from z_data_copy() in kernel/xip.c)
```
z_early_memcpy(&__data_region_start, &__data_region_load_start,
__data_region_end - __data_region_start);
```
By default, LLVM LLD aligns both VMA and LMA to the same value, but
when --omagic (-N) option is provided then only the first output section
of given region has aligned LMA and the difference between VMA addresses
(0 is this is the first section) is added.
As a result the difference between LMA and VMA is constant for every
section, so this emulates ALIGN_WITH_INPUT option present in GNU LD
(required by XIP systems).
The --omagic flag is defined in cmake/linker/lld/target_baremetal.cmake
Example:
```
MEMORY {
ROM : ORIGIN = 0x1000, LENGTH = 1K
RAM : ORIGIN = 0x11000, LENGTH = 1K
}
SECTIONS {
.text 0x1000 : {
*(.text*)
} >ROM
.data.rel.ro : {
*(.data.rel.ro)
} >RAM AT>ROM
.data : {
*(.data*)
} >RAM AT>ROM
}
```
```
echo '.globl _start; _start: nop; .byte 1;'\
'.data.rel.ro; .balign 16; .byte 0;'\
'.data; .balign 32; .byte 0;' | \
llvm-mc -filetype=obj -triple=arm - -o test.o
armv7m-cros-eabi-ld.lld --sort-section=alignment -N -T script.ld \
test.o -o lld_out
```
```
Idx Name Size VMA LMA File off Algn
0 .text 00000005 00001000 00001000 00000094 2**2
1 .data.rel.ro 00000001 00011000 00001010 000000a0 2**4
2 .data 00000001 00011020 00001030 000000c0 2**5
```
In this example the first section has lower alignment than the following
section, but with -N option the difference between VMA and LMA is the
same for .data.rel.ro and .data sections.
For comparison, using BFD linker with --omagic option results in the
following:
```
Idx Name Size VMA LMA File off Algn
0 .text 00000005 00001000 00001000 00000094 2**2
1 .data.rel.ro 00000001 00011000 00001005 000000a0 2**4
2 .data 00000001 00011020 00001006 000000c0 2**5
```
with ALIGN_WITH_INPUT added, GNU LD adds the difference between VMA to
LMA, but doesn't align LMA of .data.rel.ro section:
```
Idx Name Size VMA LMA File off Algn
0 .text 00000005 00001000 00001000 00000074 2**2
1 .data.rel.ro 00000001 00011000 00001005 00000080 2**4
2 .data 00000001 00011020 00001025 000000a0 2**5

Zephyr provides a default NMI handler (`z_SysNmiOnReset`), which will
basically call `wfi` endlessly. It is allowed to override such handler
when CONFIG_RUNTIME_NMI=y, via `z_arm_nmi_set_handler`. However,
enabling such option also provided `z_arm_nmi_init` (via `NMI_INIT()`),
which basically sets the handler to `DefaultHandler` (a new handler that
basically printks and reboots). This is strictly not needed, and
independent of the runtime NMI option. As a result, most SoCs were
blindly calling `NMI_INIT()`, probably because of a copy&paste effect.
In the majority of cases, this was a no-op, but most SoCs do IRQ
enable/disable, making this even more convoluted. To make things worse,
the init call is expected to run after console has been initialized (for
printk to work?), but most SoCs just called it in PRE_KERNEL_1+0.
This patch just drops this NMI initializer API, and leaves only the
handler set call when CONFIG_RUNTIME_NMI=y.
NMI_INIT() dummy definition is left in this patch to preserve
bisectability, will be dropped later.

The CDC ACM implementation provides a virtual UART interface
that is used by various samples and subsystems in a way that is
compatible with the real UART interface.
Commit cc1b2c70cc
("uart: doc: Add special case for virtual UART")
added a questionable comment to uart_fifo_fill() API
description in an attempt to fix issue described in
https://github.com/zephyrproject-rtos/zephyr/issues/11455
However, this did not fix the problem because the API is not
designed to be used in this way. Finally commit 0e57e4fb78
("samples: usb: cdc_acm: Update CDC ACM echo sample")
revised the sample to use the API in the correct way.
Remove incorrect comment in uart_fifo_fill(). For compatibility
reasons and due to the design of the API, such differences must not
exist.
