[U-Boot-Users] CFG_MEMTEST_START board configuration setting

Hi guys. Here is an easy one.

I have a question about a certain configuration setting (two of them to be precise) in board configuration file (include/configs) .

CFG_MEMTEST_START, CFG_MEMTEST_END - usually are set to only part of the memory range. Is this because the test is time-consuming? What are the guidelines for selecting this range?

Thanks.
