I'm using current 265876 and did not change the source code except for
am335x.dtsi and beaglebone-black.dts.
ubldr is built to change the load address as follows:
# cat ubldr_make.sh
buildenv=`make -C /usr/src TARGET=arm TARGET_ARCH=armv6 buildenvvars`
eval $buildenv make -C /usr/src/sys/boot obj
eval $buildenv make -C /usr/src/sys/boot UBLDR_LOADADDR=0x88000000 all
# sh ubldr_make.sh
# cp /usr/obj/arm.armv6/usr/src/sys/boot/arm/uboot/ubldr \
/mnt/ubldr
(maybe need to cp /usr/src/share/mk/src.opts.mk /usr/share/mk/)
u-boot (MLO, u-boot.img) is u-boot-2014.04 and apply these patch:
http://lists.freebsd.org/pipermail/freebsd-arm/2014-April/007922.html
uboot-2013.04_api_api_storage.c.patch
uboot-2014.04_drivers_mmc_mmc.c.patch
According to the third patch, it seems to retry when
mmc_send_op_cond is failed. I don't know why it failed.
