k3_mem_map_init configures the MMU at runtime by querying the
device-tree for DDR size for each bank as well as creating carveouts for
OPTEE and ATF in the first bank.
Therefore add a call to k3_mem_map_init in dram_init for all k3 vendor
boards.

properly allocate the required space
for the framebuffer.
Therefore this patch adds k3_spl_mem_map_init which adds the required
MMU entry by querying the gd after the framebuffer size has been
computed in spl_reserve_video_from_ram_top.

The SPL_FS_LOAD_ARGS_NAME config is used for the arguments to the kernel

Setting it in board specific Kconfig allows us to reuse the same config
fragment 'am62x_r5_falcon.config' for all 3 platforms for enabling

Hi all,
I was trying to understand how the go command is expected to work when
used to load custom OSes. My use case requires getting a proprietary OS
to boot using the go command on a TI K3 platform. The OS expects caches
