GhostBSD ARM64 porting from x86 code base (RISC-V in the future??)

 Uart3 Serial Port,  How to locate the source code used by FreeBSD / GhostBSD-Arm64 Edit the file /etc/rc.conf  and  add the bash execution line 'set -x'  This will produce verbose output from  'make buildkernel KERNCONF=GENERIC-VCHIC   -DNO_CLEAN Issue the  'make buildkernel' command and direct stdout & stderr to a file. make buildkernel KERNCONF=GENERIC-VCHIQ -DNO_CLEAN > BRCM64_GENERIC-VCHIQ.txt 2>&1  later you can run make installkernel KERNCONF=GENERIC-VCHIQ ===> wlan_tkip (install) install -T release -o root -g wheel -m 555   wlan_tkip.ko /boot/kernel/ install -T dbg -o root -g wheel -m 555   wlan_tkip.ko.debug /usr/lib/debug/boot/kernel/ ===> wlan_wep (install) install -T release -o root -g wheel -m 555   wlan_wep.ko /boot/kernel/ install -T dbg -o root -g wheel -m 555   wlan_wep.ko.debug /usr/lib/debug/boot/kernel/ ===> wlan_xauth (install) install -T release -o root ...

I.e. on my CM4 DUT   You add a line to the  config.txt  file to apply a  Device Tree overlay .  dtoverlay=uart4 dtoverlay=uart3 or dtoverlay=uart3,ctsrts //here I trying both with and without "ctsrts" gives me pi@64bit-test:~ $ raspi-gpio get BANK0 (GPIO 0 to 27): GPIO 0: level=1 fsel=0 func=INPUT pull=UP GPIO 1: level=1 fsel=0 func=INPUT pull=UP GPIO 2: level=1 fsel=0 func=INPUT pull=UP GPIO 3: level=1 fsel=0 func=INPUT pull=UP GPIO 4: level=1 fsel=3 alt=4 func=TXD3 pull=NONE GPIO 5: level=1 fsel=3 alt=4 func=RXD3 pull=UP GPIO 6: level=1 fsel=0 func=INPUT pull=UP GPIO 7: level=1 fsel=0 func=INPUT pull=UP GPIO 8: level=1 fsel=3 alt=4 func=TXD4 pull=NONE GPIO 9: level=1 fsel=3 alt=4 func=RXD4 pull=UP GPIO 10:...
