Google searches weren't helping me solve that one, so I dug into
the Makefile a bit.
Short answer seems to be to change this line in the Makefile:
-DTC_FLAGS += -Wno-unit_address_vs_reg
+#DTC_FLAGS += -Wno-unit_address_vs_reg
..when I did that, it breezed through the build without errors.
Will move onward to try to get an error free result.

Regarding figuring out how to solve the above, it was obvious 'make'
wasn't showing the commands being used to build the targets, so I wanted
to see what was going on when it failed.
The Makefile comments indicate there's some kind of convention to keeping
the noise of the build down, using two Makefile variables 'quiet' and 'Q'.
I found I could get make to show the commands being executed by changing
this section of the Makefile:
ifeq ($(KBUILD_VERBOSE),1)
quiet =
Q =
else
- quiet=quiet_
- Q = @
+ quiet=
+ Q =
endif
With that modification, running 'make' showed the full command
being executed. So instead of just showing this:
DTC src/arm/am437x-gp-evm.dtb
FATAL ERROR: Unrecognized check name "unit_address_vs_reg"
..it now showed the full commands being executed:
make ARCH=arm all_arch
cpp -Wp,-MD,src/arm/.am437x-gp-evm.dtb.d.pre.tmp -nostdinc -Iinclude
-Isrc/arm -Itestcase-data -undef -D__DTS__ -x assembler-with-cpp -o
src/arm/.am437x-gp-evm.dtb.dts.tmp src/arm/am437x-gp-evm.dts ; /usr/bin/dtc -O
dtb -o src/arm/am437x-gp-evm.dtb -b 0 -@ -i src/arm -Wno-unit_address_vs_reg -d
src/arm/.am437x-gp-evm.dtb.d.dtc.tmp src/arm/.am437x-gp-evm.dtb.dts.tmp ; cat
src/arm/.am437x-gp-evm.dtb.d.pre.tmp src/arm/.am437x-gp-evm.dtb.d.dtc.tmp >
src/arm/.am437x-gp-evm.dtb.d
FATAL ERROR: Unrecognized check name "unit_address_vs_reg"
There's actually three commands being run in one line there;
cpp, dts, and cat. The 'dts' line is the one that failed:
/usr/bin/dtc -O dtb -o src/arm/am437x-gp-evm.dtb -b 0 -@ -i src/arm
-Wno-unit_address_vs_reg -d src/arm/.am437x-gp-evm.dtb.d.dtc.tmp
src/arm/.am437x-gp-evm.dtb.dts.tmp
..and there's the "-Wno-unit_address_vs_reg" flag that dtc was
complaining about.
The man page for dtc doesn't describe a -W flag, but I'm assuming
it's a compiler warning flag of some kind, perhaps like gcc's.
