If the Cortex-M4 core is booting from SDRAM, the memory region must beconfigured as Strongly Ordered. Note that the Cortex-M4 core does notseem to implement speculative prefetching, so there is no need to protectthe whole region from speculative prefetching with a second MPU region.Signed-off-by: iabdalkader <i.abdalkader@gmail.com>

This patch allows removing the Open-AMP section used for the resource tableby loading it manually. The Open-AMP ELF loader would attempt to load thissection if the firmware is built for SDRAM.Note that since we're not using copy tables or ARM CC, the resource tablehas always been copied manually.Signed-off-by: iabdalkader <i.abdalkader@gmail.com>

…irmware.To load the M4 firmware into SDRAM, we must ensure the linker script does notinclude any loadable sections that are placed in the shared memory region. Ifsuch sections exist, the ELF loader will overwrite the shared memory regionwhen loading the firmware.Additionally, the Open-AMP section is no longer required, as the resource tableis now populated manually in resource_table_init. Therefore, this section canbe removed.Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
