[U-Boot-Users] difference between _f and _r init functions

[Mike Frysinger]

cant seem to find any explicit mention of the difference between _f and _r 
functions ... looks like _f funcs are called "early" and _r funcs are the 
later stuff which do more.  what's the letter stand for and generally what 
should these be doing ?

In my current case (old U-Boot, ppc 8xx) _f runs from _f_lash, not
yet relocated, setup of and access through function pointers needs
special care, very few RAM (and stack size) available.
_r runs after relocation from _R_AM, nomal mode, no special care
required.
