This selects CONFIG_BT_HCI_RAW_H4 which indicates to hci_raw to handle
H:4 header automatically.
Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
This makes hci_raw to manage RX and TX buffers so its logic don't have
to be replicated on each an every driver/application, it also makes it
simpler to deal with extra headers for H:4 mode since that then can be
done at earlier at buffer allocation.

This adds support for registering a command extention table which is

The unique identifier for this platform is a 96-bit value, where the
upper 56 bits provide an ASCII encoding of the lot number, and the
lower 40 bits provide the wafer number and X, Y position on the wafer.

This commit reworks the ARM AArch32 non-Cortex-M (i.e. Cortex-A and

This commit adds an "extension" header for the CMSIS to provide the
core register access functions and macros that are not currently
available in the CMSIS.
The functions and macros defined in this header should be eventually
added to the upstream CMSIS and, once added, removed in this header.

In the ARM Cortex-M architecture implementation, the concepts of
"exceptions" and "interrupts" are interchangeable; whereas, in the
Cortex-A/-R architecture implementation, they are considered separate
and therefore handled differently (i.e. `z_arm_exc_exit` cannot be used
to exit an "interrupt").
This commit fixes all `z_arm_exc_exit` usages in the interrupt handlers
to use `z_arm_int_exit`.
NOTE: In terms of the ARM AArch32 Cortex-A and Cortex-R architecture
implementations, the "exceptions" refer to the "Undefined
Instruction (UNDEF)" and "Prefetch/Data Abort (PABT/DABT)"
exceptions, while "interrupts" refer to the "Interrupt (IRQ)",
"Fast Interrupt (FIQ)" and "Software Interrupt/Supervisor Call
(SWI/SVC)".

The exception/fault handling mechanisms for the ARM Cortex-M and the
rest (i.e. Cortex-A and Cortex-R) are significantly different and there
is no benefit in having the two implementations in the same file.
This commit relocates the Cortex-M fault handler to
`cortex_m/fault_s.S` and the Cortex-A/-R generic exception handler to
`cortex_a_r/exc.S` (note that the Cortex-A and Cortex-R architectures
do not provide direct fault vectors; instead, they provide the
exception vectors that can be used to handle faults).

The amount of shared code in exc_exit.S between the ARM Cortex-M and
the rest (i.e. Cortex-A and Cortex-R) is minimal and there is little
benefit in having the two implementations in the same file.
This commit splits the interrupt/exception exit code for the
Cortex-A/-R and Cortex-M into separate files to improve readability as
well as maintainability.

Zephyr being an OS is typically expected to run at EL1. Arm core
can reset to EL3 which typically requires a firmware to run at EL3
and drop control to lower EL. In that case EL3 init is done by the
firmware allowing the lower EL software to have necessary control.
If Zephyr is entered at EL3 and it is desired to run at EL1, which
is indicated by 'CONFIG_SWITCH_TO_EL1', then Zephyr is responsible
for doing required EL3 initializations to allow lower EL necessary
control.
The entry sequence is modified to have control flow under single
'switch_el'.
Provisions added by giving weak funcions to do platform specific
init from EL3.
