   4 Subject: mkimage: check environment for dtc binary location
   5
   6 Currently mkimage assumes the dtc binary is in the path and fails
   7 otherwise. This patch makes it check the DTC environment variable first
   8 for the dtc binary and then fall back to the default path. This makes
   9 it possible to call the u-boot build with make DTC=... and build a fit
  10 image with the dtc binary not being the the default path.
