Enabling POST in Uboot

I need to enable the uboot POST for testing memory and spi on the Zed board (Xilinx Zynq®-7000 All-Programmable SoC - ARM dual-core Cortex™-A9 + 28 nm programmable logic with Analog Devices AD-FMCOMMS3-EBZ FMC module featuring the AD9361).


Can this be achieved only by modification of the uboot source code ? Or, is there any sequence of keystrokes at the time of booting, for enabling the same?


I understand from the source code that there are some define directives like CONFIG_POST, CONFIG_SYS_POST_MEMORY, CONFIG_SYS_POST_SPI which control this. If modification of the source code the only way to achieve this, what changes are required in the source files ?
