2012-03-18bootstage: Make use of BOOTSTAGE_ID_RUN_OS in show_boot_progress()Simon Glass
This changes the number 15 as used in boot_stage_progress() to use the new name provided for it. This is a separate patch because it touches so many files. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
2011-10-15punt unused clean/distclean targetsMike Frysinger
The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
2010-10-21a4m072: change 'display' command implementationIlya Yanok
This patch changes implementation of 'display' command for a4m072 that uses 7-segment LED display as customer requested: a) The "display" command shall _not_ turn on the decimal point. b) Exception: "display ." shall turn on (only) the decimal point. c) Hex digits (0-9, A-F, a-f) shall be displayed as usual. d) Letters U, P, Y, L, S, T, H shall be displayed as usual (lower case letters identical to upper case letters) e) 'I' (and 'i') shall be displayed like '1' f) 'O' (and 'o') shall be displayed like '0' g) all other Characters shall be displayed like ' ' (all segments off).

2010-10-18Rename TEXT_BASE: fix merge conflictsWolfgang Denk
Commit 14d0a02a "Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE" missed a few places, especially for boards that were added inbetween. Fix the remaining issues. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-10-12a4m072: support for SHOW_BOOT_PROGRESS feature using LED displayIlya Yanok
This patch adds support for displaying boot progress codes on a4m072 board using LED display. As we can display only one symbol at any time on the hardware (two symbols with blinking) we can't display progress codes directly and have to map them to 2-symbol codes. We use the following mapping on the a4m972 board: [1, 8] U [100, 108] -> 5 [-9, -1] U [-101, -100] U [-113, -103] -> -5 [9, 14] U [120, 123] U [125, 129] -> 8 [-13, -10] U [-122, -120] U [-127, -124] U {-129} -> -8 {15} -> 9 [-32, -30] -> -A [-40, -35] U [-51, -42] U [-58, -53] U [-83, -80] U {-64, -130, -140, -150} -> -B Other progress code are ignored. One symbol codes are displayed steady while two-symbol codes are displayed using blinking. Boot progress codes are displayed with decimal got unset (as opposed to 'display' command output).

2010-10-12a4m072: led display supportIlya Yanok
This patch adds support for LED display on a4m072 board. Hardware is capable of displaying only one symbol at any time. We support displaying two symbols in software (via blinking). Signed-off-by: Ilya Yanok <yanok@emcraft.com>
