I want to use the kexec/kdump feature of linux kernel,  after add these two features,  I got compiling error.   I found the error will gone if I specify PHYSICAL_START as non-zero.  The default value is 0x0.

This is the steps:
  --enable-board=fsl-t1xxx-32b \
  --enable-build=production \
  --enable-jobs=4 \
  --enable-kernel=standard \
  --enable-parallel-pkgbuilds=4 \
  --enable-rootfs=glibc_std+debug \
  --enable-reconfig=yes \
  --with-rcpl-version=0003 \

make -C build

error messages:
