[PATCH V6 00/10] Update SPL splashscreen framework for AM62x
This patch series aims at updating SPL splashscreen framework for AM62x.
This patch series depends on https://lore.kernel.org/u-boot/20230504225829.2537050-1-sjg@chromium.org/
This series: - Fixes compilation issues in case splash related configs are not defined in SPL. - Does page table setup, dram initialisation and dcache enabling in one function call spl_enable_dcache. - Allows passing of framebuffer from spl to u-boot, eliminating flicker.
V6: - Add patch [1] from Samuel Dionne-Riel fixing CMD_BMP/BMP dependecy.
V5: - Change A53 SPL DDR layout from ASCII table to tabular format.
V4: - Fix commit message. - Introduce patch defining DDR layout in A53 SPL. - Add Reviewed-by tags.
V3: - Fix spacing issues. - Add Reviewed-by tag. - Replace #if with if in patch common: spl: spl: Remove video driver - Add link to updated memory map.
V2: - Update cover letter. - Fix commit message.

At SPL stage when stack is relocated, the stack pointer needs to be updated, the stack pointer may point to stack in on chip memory even though stack is relocated.

Use spl_dcache_enable, in place of setup_dram, arch_reserve_mmu to set up pagetable, initialise DRAM and enable Dcache to avoid multiple function calls.
Check for CONFIG_SPL_VIDEO in place of CONFIG_SPL_VIDEO_TIDSS to prevent any build failure in case video config is not defined and video related functions are called.
Check for CONFIG_SPL_SPLASH_SCREEN and CONFIG_SPL_BMP before calling splash_display to avoid compilation failure.

U-boot proper can use frame buffer address passed from SPL to reserve the memory area used by framebuffer set in SPL so that splash image set in SPL continues to get displayed while u-boot proper is running.
Put the framebuffer address and size in a bloblist to make them available at u-boot proper, if in u-boot proper CONFIG_VIDEO is defined.
