They are just symbolic names given to MTD partitions - more useable than 
mtdblock0...N.  Also, some tools look for specific partition names, such 
as the flatfsd daemon looking for /dev/flash/config

This mapping is created in the vendors/XXX/YYY/Makefile

Many of the mainline kernel options have help text associated with them, 
accessible within the menuconfig tool.  For others if you grep over the 
config.in files where they are defined, and thus get the CONFIG_XXXXYYYY 
name, after which google is likely to be helpful.

e.g. trying to find options to do with VGA, you could try something like

<uClinux-2.4.x> $ find . -name '[cC]onfig.in' | xargs grep -i vga

...

Hope this helps,

John
