In order to reuse code, the reset() function is used both to handle the
reset HCI command but also to initialize the internal HCI variables when
bringing up the system. In the latter case, avoid setting the reset bit
in the state atomic and signalling the polling API, since that is not
required during initialization.

As a preparation for advanced filtering (Controller-based privacy) this
commit refactors whitelisting so that it becomes its own module and
actually correctly performs state tracking to avoid modifying the
whitelist when it's in use.
Additionally it also removes the duplicate separate entries for
advertising and scanning, since the specification only allows one single
global whitelist singleton.

Add a separate section in the linker to place the MMU configuration
information. This location is read by the gen_mmu.py script to

In crt0.S the MMU is initialized. It uses the statically build
page tables. Here 32-bit paging scheme is used, thereby each page
table entry maps to a 4KB page. The valid regions of the memory are
specified by SOC specific file(soc.c).

Macro is used to create a structure to specify the boot time
page table configuration. Needed by the gen_mmu.py script to generate
the actual page tables.
Linker script is needed for the following:
1. To place the MMU page tables at 4KByte boundary.
2. To keep the configuration structure created by
the Macro(mentioned above).

Under invalid host behavior, trying to start advertising
while already active would corrupt the advertiser context.
This is fixed by having an explicit flag to check whether

From
http://pubs.opengroup.org/onlinepubs/7908799/xns/netinetin.h.html:
in_addr_t
An unsigned integral type of exactly 32 bits.
[] the in_addr structure [] includes at least the following member:
in_addr_t s_addr
In other words, POSIX requires s_addr to be a single integer value,
whereas Zephyr defines it as an array, and then access as s_addr[0]
everywhere. Fix that by following POSIX definition, which helps to
port existing apps to Zephyr.

The .balign directives were not working correctly in their
previous positions as the directive was applying to the section
before the variable's section, causing in some builds the
variables to be misaligned, and accesses to them causing faults.
With the alignments after the section declaration, the variables
will now be aligned as specified. Any future variable declarations
should use this form instead to ensure proper alignment.

Both the ARM and NXP MPU drivers incorrectly calculated the region index
by assuming the region type (e.g., THREAD_STACK_GUARD_REGION) was
zero-indexed, when in reality it is one-indexed. This had the effect of
wasting one region.
Signed-off-by: Maureen Helm <maureen.helm@nxp.com>
The NXP MPU requires special handling of region descriptor 0 to
guarantee that the debugger has access to the entire address space. It
does not allow writes from the core to affect the start or end
addresses, or the permissions associated with the debugger.
The original implementation of this driver attempted to work around
region descriptor 0, resulting in an off-by-1 error caught by Coverity.
Instead, define region descriptor 0 explicitly in the mpu_regions array,
and add some asserts to ensure that one doesn't try to change its start
or end addresses. This has an added benefit such that more permissions
can be enabled in region 0 if desired, whereas the previous
implementation always forced all writable permissions to be cleared.

The original implementation of _get_num_regions() parsed the CESR[NRGD]
register field to determine the number of mpu region descriptors
implemented in hardware. There was a possible path in the code to return
zero, which would cause underflow later on in arm_core_mpu_configure().
Coverity complained despite an assert to catch this condition. Instead,
use a preprocessor macro from mcux that defines the number of mpu region
descriptors.

If we receive a HTTP request and if the earlier context is still
active and it is not the same as the new one, then close the earlier
one. Otherwise it is possible that the old context will be left into
TCP ESTABLISHED state and would never be released. Example of this
is that we had IPv4 connection active and then IPv6 connection is
established, in this case we will disconnect the IPv4 connection
after this commit.

This adds shell_exec which can be used to execute commands directly
without the use of a console which is useful for both testing as well
as interfacing with applications/upper layer which would like to have

In addition to that this may be more trivial to interface with instead
of using fifos like uart_register_input and telnet_register_input do.
