Please change the git comment to a more reasonable description.

See the example below for a similar config for N1 platform.

config: add arm neoverse N1 SDP configuration

Arm N1 SDP is an infrastructure segment development platform based on
armv8.2-a Neoverse N1 CPU. For more information, refer to:
https://community.arm.com/developer/tools-software/oss-platforms/w/docs/440/neoverse-n1-sdp

Add meson build support as well. See config/arm/*

Is emag platform is only armv8? If it is supports lse then add that as well.
See mk/machine/octeontx2/rte.vars.mk as example

If it has dedicated mcpu support then add the following
MACHINE_CFLAGS += $(call rte_cc_has_argument, -mcpu=your_cpu)
