[meta-xilinx] AMP using Yocto meta-xilinx

I'm trying to configure Yocto Linux with meta-xilinx layer to do AMP on a
zedboard.
I'm following the ug978 AMP guide and trying to configure the kernel
similarly:

1. Enable loadable module support
2. Select High Memory Support
3. Select 2G/2G User/Kernel memory split
4. Enable userspace firmware loading support
5. Enable rpmsg driver
6. Enable remoteproc driver

I am looking for these options in
meta-xilinx/conf/machine/boards/common/linux/zynq/defconfig_3.14.cfg.  Is
this the correct place?

For #1, do these options accomplish loadable module support?
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
CONFIG_MODULE_FORCE_UNLOAD=y

For #2, CONFIG_HIGHMEM=y

Can someone help me with #3-5?  I don't know what options corresponds with
those, or if that is even the right file to look for them.

For #6, how would I get the zynq remoteproc driver into the kernel using
Yocto and meta-xilinx?  I'm assuming #1-5 are standard kernel
configurations, but #6 is zynq specific and wouldn't be a standard kernel
config item.

Thank you for any help.
