If you don't plan on using the debug features, then by all means
disable this feature and save 16KiB of RAM!
NOTE: There is an issue with capturing data in the RAMLOG: If

the RED LED will be blinking at about 2Hz.
That is another good reason to disable the RAMLOG!
5. This configuration executes out of SDRAM flash and is loaded into
SDRAM from NAND, Serial DataFlash, SD card or from a TFTPC sever via
U-Boot, BareBox, or the DRAMBOOT configuration described above. Data
