Dear Kushwaha Prabhakar-B32579,

First, documentation of CONFIG_ options belongs into the central
README, so we have it all in a single place.

Second, "Enables code taking care of above mentioned rule" is not
really helpful to understand what it's actually doing.

The name of the cvariable suggests that this defiens a E500 core
based system, but it does not even contain a slight hint that it has
something to do with debugging.

Also, what's the "V1_V2" ? Are there also other systems (say, e500 v3
cores), and are this not affected? We already have CONFIG_E500 and
CONFIG_E500MC so CONFIG_E500_V1_V2 appears to belong to this group,
but if I understand your intentions it does something completely

All this is highly confusing.

Best regards,

Wolfgang Denk
