7e36bd31fe arch: aarch64: Use SP_EL0 instead of SP_ELx
ARM64 is currently using SP_ELx as stack pointer for kernel and threads
because everything is running in EL1. If support for EL0 is required, it
is necessary to switch to use SP_EL0 instead, that is the only stack
pointer that can be accessed at all exception levels by threads.

While it is not required to keep using SP_EL0 also during the
exceptions, the current code implementation makes it easier to use the
same stack pointer as the one used by threads also during the
exceptions.

This patch moves the code from using SP_ELx to SP_EL0 and fill in the
missing entries in the vector table.

4331c05f17 net: lwm2m: Allow to acknowledge request early from the callback
LwM2M engine by default sends piggybacked responses for requests after
all callbacks are executed. This approach however isn't good enough if
the application callback executes some lenghty operations (for instance
during FW update). Delaying the ACK may result in unnecessary
retransmissions.

This commits adds an API function which allows to send an early empty
ACK from the application callback. This prevents further retransmissions
from the server side. After all callbacks are executed, the LwM2M engine
will send the response as a separate CON message.

c2d852a171 device: refactor to allow direct access to devicetree device structures
When using a devicetree node as an identifier we know the identifier
used to define the device structure.  This allows code to directly
reference that structure, avoiding the need to look it up by label at
runtime.

Change the macros so DEVICE_DT_* device objects are globally visible
using the node identifier as the object identifier.

Also add the necessary API to verify that a device that was captured
at build time successfully completed initialization and any other
steps necessary before it can be safely used.

f66e5c4cb0 drivers: pcie_ep: Add API to achieve data transfer with system DMA
Introduce common API to achieve data transfer using system DMA.
"System DMA" uses the outbound memory mapped Host address,
it cannot understand Host/PCIe address.

This API will take of mapping the Host address, completing
the data transfer to/from Host memory and unmapping the window;
thus providing abstraction to the user.

7bce8406d6 pcie: endpoint: Add public API for data transfer with System DMA
For a given PCIe EP device, data transfer to/from Host memory can be
achieved with "System DMA" between mapped Host memory
(PCIe outbound memory) and EP device's local memory if EP is equipped
with a "System DMA controller".
Add public API to enable such DMA transfers.

The term "System DMA" is used to clarify that we are not talking about
dedicated "PCIe DMA"; rather the one which does not understand PCIe
address directly, and uses the mapped Host memory.

e671d363b8 drivers: memc: stm32: initial support for stm32 FMC
This commit adds a new driver category for memory controller
peripherals. There is no API involved for now, as it has not been found
necessary for first implementation.

STM32 Flexible Memory Controller (FMC) is the only controller supported
for now. This peripheral allows to access multiple types of external
memories, e.g. SDRAM, NAND, NOR Flash...

The initial implementation adds support for the SDRAM controller only.
The HAL API is used, so the implementation should be portable to other
STM32 series. It has only been tested on H7 series, so for now it can
only be enabled when working on H7.

Linker facilities have also been added in order to allow applications to
easily define a variable in SDRAM.

76b3a50e7f logging: add padding for RISC-V 64bits environment
This patch add padding in filter structure of log system.
In RISCV && 64BIT environment. Log system is facing alignment bug.

struct log_source_dynamic_data {
	uint32_t filters;
};

static inline uint32_t *log_dynamic_filters_get(uint32_t source_id)
{
	return &__log_dynamic_start[source_id].filters;
}

A sizeof(log_source_dynamic_data) = 4, address offset of
&__log_dynamic_start[] are:
  - &__log_dynamic_start[0]: +0
  - &__log_dynamic_start[1]: +4
  - &__log_dynamic_start[2]: +8

But RISCV 64bit gcc/ld places each log_dynamic_log, log_dynamic_os
and log_dynamic_test per 8bytes alignment. So address offset of
log_dynamic_* are:
  - &log_dynamic_log : +0
  - &log_dynamic_os  : +8
  - &log_dynamic_test: +16

tests/subsys/logging/log_core cannot set correct log filters in
RISCV && 64BIT environment, so test is always going to fail.

This commit makes the following tests pass on qemu_leon3:

Details:

sparc-zephyr-elf-gcc 9.2.0 compiles the beginning of
net_ipv6_addr_create_iid(),

  addr->s6_addr[0] = 0xfe;
  addr->s6_addr[1] = 0x8e;
  UNALIGNED_PUT(0, &addr->s6_addr16[1]);
  UNALIGNED_PUT(0, &addr->s6_addr32[1]);

into

  400089d4 <net_ipv6_addr_create_iid>:
  400089d4:       9d e3 bf a0     save  %sp, -96, %sp
  400089d8:       03 3f a0 00     sethi  %hi(0xfe800000), %g1
  400089dc:       c0 2e 20 04     clrb  [ %i0 + 4 ]
  400089e0:       c2 26 00 00     st  %g1, [ %i0 ]
  400089e4:       c0 2e 20 05     clrb  [ %i0 + 5 ]
  400089e8:       c0 2e 20 06     clrb  [ %i0 + 6 ]
  400089ec:       c0 2e 20 07     clrb  [ %i0 + 7 ]

%i0 is the function argument "addr". %g1 is prepared with the value
0xfe800000. The "clrb" instruction sets a single byte in memory to
0 and has no alignment restriction.

We get an unaligned exception on PC 400089e0 when %i0 ("addr") is
not a multiple of 4. The instruction "st" stores the full 32-bit
register %g1 to memory address in %i0. The effective address (%i0)
of the 32-bit register store is required to be naturally aligned by
the architecture.

The compiler assumes that "addr" is aligned according to its type
and has knowledge about the data representation.
