Subject: [PATCH 0/9] Add STM32MP25 SPI NOR support

From: Patrice Chotard <patrice.chotard@...s.st.com>

This series adds SPI NOR support for STM32MP25 SoCs from STMicroelectronics,
for that it adds support for:
  - Octo Memory Manager driver.
  - Octo SPI driver.
  - yaml schema for Octo Memory Manager and Octo SPI drivers.

The device tree files adds Octo Memory Manager and associated Octo SPI instances
in stm32mp251.dtsi and adds SPI NOR support in stm32mp257f-ev1 board.
