fsl-layerscape: dpaa: fix fsl-mc status in fdt with bootefi
fsl-mc lazyapply command applies dpl from efi_exit_boot_services(). Status of fsl-mc node in working fdt is updated at this stage. However, an efi application like grub may already have copied the fdt. So the updates to fdt done at efi_exit_boot_services() may not be visible to the OS. Fix it by updating fdt earlier if fsl-mc lazyapply command is used. Fixes: b7b8410a8f (ls2080: Exit dpaa only right before exiting U-Boot) Signed-off-by: Mian Yousaf Kaukab <ykaukab@suse.de> Reviewed-by: York Sun <york.sun@nxp.com>
