Yes this is definitely an issue, I just ran into this when trying to
build and test U-Boot for AM43xx HS which is when I saw your response.
However even after fixing this I get additional build errors from SPI,
USB Gadget, and UART related routines such as...
cmd/built-in.o: In function `do_spi_xfer':
/home/a0797059/git/u-boot/cmd/spi.c:61: undefined reference to `spi_setup_slave'
/home/a0797059/git/u-boot/cmd/spi.c:68: undefined reference to `spi_claim_bus'
/home/a0797059/git/u-boot/cmd/spi.c:71: undefined reference to `spi_xfer'
/home/a0797059/git/u-boot/cmd/spi.c:88: undefined reference to `spi_release_bus'
/home/a0797059/git/u-boot/cmd/spi.c:90: undefined reference to `spi_free_slave'
<cut>
I'll be digging into this a bit more to see where that comes from.
