In trying to get Zephyr RTOS working on the Nucleo U545RE-Q board, I discovered header inclusion issues building the HAL for the STM32U545 SoC.
Zephyr RTOS makes use of the "stm32u5xx_hal_driver" for some interactions with the ST hardware, and builds the HAL by copying the default "stm32_hal_conf_template.h" to "stm32_hal_conf.h", leaving all options enabled.
However, some of the modules (specifically HAL_SRAM_MODULE_ENABLED, HAL_NAND_MODULE_ENABLED and HAL_NOR_MODULE_ENABLED) do not compile for the STM32U545. Based on recommendations from a engineer in the Zephyr forums, I modeled changes to four files ((stm32u5xx_hal_sram.h, stm32u5xx_hal_nor.h, stm32u5xx_hal_nand.h and stm32u5xx_ll_fmc.h) with appropriate "#ifdef" checks using the example for the "stm32g4xx_hal_driver", and this allows the code to build for the U545 series.
