From cdb749778aa3a8f8d2a41dd4ad811ef822aecfe6 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sat, 24 Jul 2010 21:55:43 +0200 Subject: 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 Acked-by: Detlev Zundel --- arch/m68k/lib/board.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'arch/m68k/lib/board.c') diff --git a/arch/m68k/lib/board.c b/arch/m68k/lib/board.c index 732023d67..b254079ae 100644 --- a/arch/m68k/lib/board.c +++ b/arch/m68k/lib/board.c @@ -134,7 +134,7 @@ typedef int (init_fnc_t) (void); static int init_baudrate (void) { char tmp[64]; /* long enough for environment variables */ - int i = getenv_r ("baudrate", tmp, sizeof (tmp)); + int i = getenv_f("baudrate", tmp, sizeof (tmp)); gd->baudrate = (i > 0) ?
