[PATCH 6/7] video: stm32: stm32_ltdc: align framebuffer on 2MB

2021-11-15 Thread Patrick Delaunay
Align the framebuffer size on MMU_SECTION_SIZE in kernel, = max 2MB for LPAE for armV7, to avoid issue with the simple frame buffer activation, when U-Boot add a reserved memory in the kernel device tree to preserve the splash screen until Linux driver initialization. See Linux documentation for
