NVIC_Relocate, NVIC_SetVector, NVIC_GetVector prototypes were defined in a lot of places. Now they are put in one header. Signed-off-by: Jerzy Kasenberg <[email protected]>
New function NVIC_DisableAll() disables all interrupts on NVIC. Cortex_DisableAll() disables all interrupts and SysTick Those function are intended to be called from hal_bsp_deinit to disable interrupts before application code reconfigures them from what boot loader set up.

For CortexM devices add call to Cortex_DisableAll() that will disable all interrupts before control is passed from bootloader to application Signed-off-by: Jerzy Kasenberg <[email protected]>
Function NVIC_Relocate() was called in SystemInit() which is in file from Nordic. Now call is moved to mynewt specific function hal_system_init that is called just after SystemInit finishes. This is done to leave file from external source as close to origin as possible in case of future update. Signed-off-by: Jerzy Kasenberg <[email protected]>
After NVIC_Relocate() was moved to different header all hal_system_init needs additional include Some leftover code was also cleaned. Signed-off-by: Jerzy Kasenberg <[email protected]>
NVIC_Relocate call was placed in NXP generated file. Now it is moved to hal_system_init function that is way it's done in mynewt Startup code for usbmkw41z now calls hal_system_init as is the case for all mynewt platforms Signed-off-by: Jerzy Kasenberg <[email protected]>
This switches to autogenerated linker scripts for CortexM. Signed-off-by: Jerzy Kasenberg <[email protected]>
NVIC_Relocate call was placed in Ambiq generated file. Now it is moved to hal_system_init function that is way it's done in mynewt hal_bsp_deinit() disable NVIC interrupts as well. Signed-off-by: Jerzy Kasenberg <[email protected]>
NVIC_Relocate call was in two places Now it is only in hal_system_init function that is way it's done in mynewt Signed-off-by: Jerzy Kasenberg <[email protected]>

Function
NVIC_DisableAll()disable all interrupts on NVIC controller.Cortex_DisableAll()disables all NVIC interrupts and stops SytTick that also can generate interrupt.Call to
Cortex_DisableAll()is added to all hal_bsp_deinit() functions that are executed before control is passed from the bootloader ot the application.In some cases hal_bsp_deinit was added.
hal_system_init()was added to platforms that did not have this function.Now
hal_system_init()callsNVIC_Relocate()(previously NVIC_Relocate was often called fromSystemInit()that is usually provided by MCU manufacturer. So mynewt had copies of those files with local modifications that made it harder to maintain in case of upgrade.Same prototypes
were placed in many headers and now are put in just one.
NXP MK8xF now uses common startup code with auto-generated linker script like ST and Nordic chips.
