Michael Jung 9b679a7860 stm32l562e-dk: Board Support
Support for the STMicroelectronics STM32L562E-DK development board. This
is a proof-of-concept port that demonstrates running NuttX as the
Non-Secure TrustZone domain companion to TrustedFirmware-M.

* respective code is in STM32CubeL5/Projects/STM32L562E-DK/Applications/TFM/
* TFM_SBSFU_Boot/Src/boot_hal.c and configures the clocks as follows:
*
* System Clock source : PLL (MSI)
* SYSCLK(Hz) : 110000000
* HCLK(Hz) : 110000000
* AHB Prescaler : 1

* PLLR : 2
* Flash Latency(WS) : 5
* Voltage range : 0
