9d8111c88f arch: arm: cortex-m: fix placement of ARMv7-M-related MPU workaround
The workaround for ARMv7-M architecture (which proactively
decreases the available thread stack by the size of the MPU
guard) needs to be placed before we calculate the pointer of
the user-space local thread data, otherwise this pointer will
fall beyond the boundary of the thread stack area.

2972cdc763 drivers: modem: ublox-sara-r4: fix getaddrinfo
The implementation of offload_getaddrinfo in this driver failed
when the node it was called with was an IP address. This condition
was never detected, and as a consequence a DNS query was done on
the IP address instead of returning it directly.

Also, the port was set first after running the DNS query.
As a consequence, if the IP address would have been returned directly,
this would have been done without a port been set.

Both errors are fixed in this patch.

cd7a73c20a Bluetooth: controller: split: Fix NRF_CCM overrun
Fix missing assignment of NRF_CCM->MAXPACKETSIZE register
for PDU sizes smaller than 251 bytes. If there is CRC errors
causing PDU length fields to be higher than configured PDU
buffer sizes in the controller, without the MAXPACKETSIZE
register set to correct PDU size, CCM module could overrun
the PDU buffer and cause memory corruption. This fix is
applicable for all nRF52 Series SoCs except nRF52832 SoC.

9adcabe38d cmake: introduction of ZephyrBuildConfiguration package
The ZephyrBuildConfiguration package allow downstream users to control
the Zephyr build system using a cmake package.

A Zephyr Build Configuration package allows for setting of additional
DTS_ROOT, BOARD_ROOT, and similar variables without having to patch
Zephyr repo, but it also allows for inclusion of additional boilerplate
code for more advanced use cases.

The repository or folder containing the Zephyr Build Configuration
package must be on toplevel in the Zephyr workspace.

e7ecdec536 drivers: uart: cc13xx_cc26xx: use PRE_KERNEL_1 init level for all UARTs
There does not seem to be a simple way to express the fact that UART1
can be initialized later at the POST_KERNEL level. The existing code
is wrong in the sense that it always initializes DT instance 1 later,
instead of doing it for UART1 (which may not be instance 1).

In addition, UART instances on other platforms are
also initialized at the PRE_KERNEL_1 level regardless of the instance
index, so let's do the same on this platform for consistency.

bacf412c7b drivers: uart: cc13xx_cc26xx: set power config based on UART base addr
The power configuration is dependent on which UART is physically used.
In order to allow DT_INST_FOREACH_STATUS_OKAY() to iterate through
instances without the assumption that index 0 corresponds to UART0
(which would be incorrect in the case when only UART1 is enabled),
we need to check the base address to identify which UART is being dealt
with.
