I mounted based on:
FreeBSD-13.1-STABLE-arm-armv7-GENERICSD-20230107-1149f0ec2b18-253362.img
doing:
# mount -onoatime -tmsdosfs /dev/da0s1 /mnt
# dtc -o am335x-boneblack-13.1.dts -O dts -I dtb -s =
/mnt/dtb/am335x-boneblack.dtb
to generate a sorted, overall .dts source.
I then dismounted and did similarly for based on:
=
FreeBSD-14.0-CURRENT-arm-armv7-GENERICSD-20230107-11b5b9e8a520-259967.img
generating a sorted, overall .dts source via:
# dtc -o am335x-boneblack-main.dts -O dts -I dtb -s =
/mnt/dtb/am335x-boneblack.dtb
(The -s sorts for making the source produced more useful for
diff activity.)
Then:
# diff -u am335x-boneblack-*.dts | more
but the diff was rather large. So:
# diff -u am335x-boneblack-*.dts | grep "^-" | wc
933 4250 36379
# diff -u am335x-boneblack-*.dts | grep "^+" | wc
1318 5774 50377
13.1 (and stable/13) are back at something like linux 5.9=20
for .dt* source but main [so: 14] is at linux 6.0 now, the
11th import after 13.1 if I counted right.
