-Added ROM setting to enable/disable feature via .cfg files. -Implemented hook at flash_decoder layer once the first 12 vectors are obtained (flash decoder min size)
-hook for custom reset button handling -hook for 30ms event tick -hook for power down event -usb state udpate
-Add KL27Z NXP drivers -Power monitor (detect power source) -Board Rev Id detection -i2c support -low power support -button and LED handling
-build filesystem hook for error blob app and DATA.BIN file creation -Added microbit custom BL project for custom URL in HELP_FAQ.HTM -I2C comms and flash interface -SWD clock speed improvements
-Make power LED remain active in VLPS mode. Changed FlexIO source clock to one that is active in VLPS. -Removed NRF Power mode property -Added Power LED sleep state property -Changed size of properties 0x01-03 to 2B

-Add property for Kl27 user event (wakeup or long button press) -Blink LED when attempting to enter deep sleep but are PC connected -Hold interrupt line to send I2C message on reset long press -Clear I2C responses after first read in the comms interface
-Change wake up when the reset button is pressed instead of released -Add hook in bootloader project to bypass reset button check to jump directly to the interface -Reset the nRF whenever we wakeup from the reset button independently of the press duration
-Keep red LED ON after a long press. -When the reset button is pressed, the KL27 will reset the `Power LED Sleep state` value to the default ON -Red LED in deep sleep mode now depends on the `Power LED Sleep state` it can be either HIGH or LOW but no PWM.

-Add support for reading flash config data -Change filesize to bytes instead of KB -Fix address ranges in erase storage cmd -Add more validations to different commands
-Keep interrupts enabled during flash operations -Shortened I2C ISR
-Disable USB regulator, it's not needed since we use external regulator -Disable more pins during power down, and disable unecessary internal pullups
-Add timeout for staying in RUN mode after waking up or receiving I2C transaction -Prevent entering sleep if I2C command is being processed -Update power source when usb is attached/detached -Don't process I2C Writes with nop cmd

- Set backdoor key to 'MICROBIT'. - Enable FPROT for first 32 kB of flash. - Fix FPROTx numbering according to KL27 RM, where FPROT3 is at address 0x408. - Enable backdoor key in FSEC. - Added asterisks next to selected options in comments for FOPT and FSEC.
(cherry picked from commit fb4d5da)
(cherry picked from commit 1d7ad5d) Modifications: -Only define MICROBIT_LOCK_BOOTLOADER for kl27z_microbit_bl project -Keep only one common: section in kl27z_microbit_bl.yaml
update formatting made microbit specific changes to be board configurable via yaml files
Fix GCC builds by closing the unterminated comment in startup_MKL27Z4.S.
