Rename getenv_r() into getenv_f()
While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
