+Targets
+=======
+The U-Boot make targets map to the available core modules as below.
+
+Integrator/AP is no longer available from ARM.
+Core modules marked ** are also no longer available.
+
+ap720t_config          ** CM720T
+ap920t_config          ** CM920T
+ap926ejs_config        Integrator Core Module for ARM926EJ-STM
+ap946es_config         Integrator Core Module for ARM946E-STM
+cp920t_config          ** CM920T
+cp926ejs_config        Integrator Core Module for ARM926EJ-STM
+cp946es_config         Integrator Core Module for ARM946E-STM
+cp1136_config          Integrator Core Module ARM1136JF-S  TM
+
+The final groups of targets are for core modules where no explicit cpu
+code has yet been added to U-Boot i.e. they all use the same U-Boot binary
+using the generic "arm_intcm" core:
+
+ap966_config                   Integrator Core Module for ARM966E-S TM
+ap922_config                   Integrator Core Module for ARM922T TM with ETM
+ap922_XA10_config              Integrator Core Module for ARM922T using Altera Excalibur

+The Makefile targets call board/integrator<>/split_by_variant.sh
+to configure various defines in include/configs/integrator<>.h
+to indicate the core module & core configuration and ensure that
+board/integrator<>/u-boot.lds loads the cpu object first in the U-Boot image.
