-=-=-=-=-=-=-=-=-=-=-= u-boot/spl onto sdcard da0 =-=-=-=-=-=-=-=-=-

/usr/ports/sysutils/u-boot-nanopi-neo/make install clean
dd if=/usr/local/share/u-boot/u-boot-nanopi_neo/u-boot-sunxi-with-spl.bin of=/dev/da0 bs=1024 seek=8

-=-=-=-=-=-=-=-= partition sdcard, 8MB msdos /boot, remainder UFS =-=-=-=-=-=-=-
 
(clear card's partitions first? gpart list/delete/destroy)
 gpart create -s MBR da0
 gpart add -t \!12 -b 1M -s 8m da0
(8MB seems alright, check map/offsets/FAT type if bigger)
 gpart set -a active -i 1 da0
 newfs_msdos -F12 /dev/da0s1

 gpart add -t freebsd da0
 gpart create -s BSD da0s2
 gpart add -t freebsd-ufs da0s2
 newfs /dev/da0s2a
 
 Filesystem flags per crochet's disk.sh functions, but journaling? On an SD card? Also HEAD's "cylinder checksum" annoying messages and eventual disk errors...
 
 tunefs -n enable /dev/da0s2a
 tunefs -j enable -S 4194304 /dev/da0s2a
 tunefs -N enable /dev/da0s2a
 
-=-=-=-=-=-=-= card ready to populate =-=-=-=-=-=-

mount_msdosfs /dev/da0s1 /mnt
cp /root/arm7obj/usr/src/arm.armv7/stand/arm/uboot/ubldr /mnt
( ^ detail buildworld/ubldr process from armbuild.sh, note new location in /stand instead of /boot, thanks HEAD)
(look into ubldr vs. ubldr.bin epic struggle of standardization)

cp /root/sun8i-h3-nanopi-neo.dtb /mnt
( ^ how was this made, why use FDT vs DTB, etc)
( /usr/src/sys/tools/fdt/make_dtb.sh /usr/src/sys /root/linuxdts/arch/arm/boot/dts/sun8i-h3-nanopi-neo.dts /root )
(used the newest dts from Linux tree for ethernet awg0 support, not sure I'm getting all the proper devices though, doublecheck USB busses)
