Apparent conflict between CONFIG_BLK and CONFIG_API

Good evening,

I am trying to port FreeBSD to the ASUS Tinker Board, a computer based
on the Rockchip 3288 SoC. FreeBSD's boot loader (named loader(8)) needs
CONFIG_API to be enabled, but trying to build an U-Boot from trunk with
both CONFIG_API and CONFIG_BLK (as required for Rockchip SoC's?) leads
to the following build failure:

$ CROSS_COMPILE=arm-none-eabi- gmake tinker-rk3288_defconfig all
...
  CC      api/api_storage.o
api/api_storage.c: In function 'dev_read_stor':
api/api_storage.c:334:9: error: 'struct blk_desc' has no member named 'block_read'
  if ((dd->block_read) == NULL) {
         ^~
api/api_storage.c:339:11: error: 'struct blk_desc' has no member named 'block_read'
  return dd->block_read(dd, start, len, buf);
           ^~
api/api_storage.c:340:1: warning: control reaches end of non-void function [-Wreturn-type]
 }
 ^

gmake[1]: *** [Makefile:1229: api] Fehler 2
gmake: *** [Makefile:460: __build_one_by_one] Error 2

I applied the following fix, but the product doesn't boot. Perhaps
that's not a property of the fix though:

Yours,
