+	  This option enables the 'post_config' command in U-Boot.
+	  The 'post_config' command is used to execute the PS7 post-configuration
+	  process after loading an FPGA bitstream file on Xilinx Zynq devices.
+	  This command ensures that the programmable logic (PL) and
+	  processing system (PS) are properly synchronized after
+	  FPGA configuration. It is specifically useful in designs where
+	  additional initialization steps are required for the PS to
+	  correctly interact with the configured PL.
+	  This option is only applicable to Xilinx Zynq platforms and
+	  has no effect on other architectures. If you are not using the
+	  PS7 subsystem or do not require post-configuration steps,
+	  this option can be disabled to reduce the size of the U-Boot binary.
