From 0c505db0a0dc1f670b13ce3b4d3fbf1ec5b3cbd2 Mon Sep 17 00:00:00 2001 From: Jon Loeliger Date: Mon, 11 Jun 2007 19:03:03 -0500 Subject: lib_*/: Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*). This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger --- lib_avr32/board.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib_avr32') diff --git a/lib_avr32/board.c b/lib_avr32/board.c index 265328a..822668c 100644 --- a/lib_avr32/board.c +++ b/lib_avr32/board.c @@ -328,7 +328,7 @@ void board_init_r(gd_t *new_gd, ulong dest_addr) jumptable_init(); console_init_r(); -#if (CONFIG_COMMANDS & CFG_CMD_NET) +#if (CONFIG_COMMANDS & CFG_CMD_NET) || defined(CONFIG_CMD_NET) #if defined(CONFIG_NET_MULTI) puts("Net: "); #endif -- cgit v1.1 From 67350568f9d46e66c21829f3513b3db0caeb948b Mon Sep 17 00:00:00 2001 From: Jon Loeliger Date: Mon, 9 Jul 2007 18:05:38 -0500 Subject: lib_{arm,avr32,blackfin,generic,i386}/: Remove obsolete references to CONFIG_COMMANDS Signed-off-by: Jon Loeliger --- lib_avr32/board.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib_avr32') diff --git a/lib_avr32/board.c b/lib_avr32/board.c index 822668c..8b9ca38 100644 --- a/lib_avr32/board.c +++ b/lib_avr32/board.c @@ -328,7 +328,7 @@ void board_init_r(gd_t *new_gd, ulong dest_addr) jumptable_init(); console_init_r(); -#if (CONFIG_COMMANDS & CFG_CMD_NET) || defined(CONFIG_CMD_NET) +#if defined(CONFIG_CMD_NET) #if defined(CONFIG_NET_MULTI) puts("Net: "); #endif -- cgit v1.1 From f7c086e94e8ce9aad7268af97f73aa6884686f27 Mon Sep 17 00:00:00 2001 From: Dirk Behme Date: Thu, 2 Aug 2007 17:41:14 +0200 Subject: Move 64bit division from avr32 to generic lib MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the 64bit division from lib_avr32 to lib_generic. With this, all boards can do_div/__div64_32 if needed, not only avr one. Code is put to lib_generic, so no larger memory footprint if not used. No code modifications. Thanks for proposal by Håvard Skinnemoen.
