With rpmsg.dtb, but when M core not kicked by U-Boot, we need set auto_boot
as false. For early boot case, we need set auto_boot as true.Tested-by: Shengjiu Wang

Parse auto boot from dtb. Currently auto boot is default
set. This will make non-m4 image suspend dump if the firmware loading
workqueue not finished. So only enable auto boot for userspace loading
when fsl,rproc-auto-boot available.Reviewed-by: Anson Huang

With upcoming changes in elf loader for elf64 support, section size will
be a u64. When used with da_to_va, this will potentially lead to
overflow if using the current "int" type for len argument. Change
da_to_va prototype to use a size_t for len and fix all users of this
function.Reviewed-by: Bjorn Andersson

Provide a basic driver to control Cortex M4 co-processor found
on NXP i.MX7D and i.MX6SX.
Currently it is able to resolve addresses between M4 and main CPU,
start and stop the co-processor. Other functionality is not provided
or test.This driver was tested on NXP i.MX7D and expected to work on
i.MX6SX as well.Signed-off-by: Oleksij Rempel
