Hi Edward,
I'm in no way an expert, I just fritter around with meta-xilinx from
time to time, but I can probably help with these. They're all kernel
configuration options, actually.

#3 is:
Kernel Features --->
Memory split (3G/1G user/kernel split) --->
(X) 2G/2G user/kernel split
and #4 is:
Device Drivers --->
Generic Driver Options --->
-*- Userspace firmware loading support

#5 and #6 are options so long as you're building linux-xlnx of some form
as your virtual/kernel:
Device Drivers --->
Remoteproc drivers --->

Rpmsg drivers --->
