* kbuild, blackfin: Add CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEEDMasahiro Yamada2014-03-07-5/+0
| | | | | | | | | | | | | | | | | | | | | | Many (but not all) of Blackfin boards give -O2 option to compile under lib/ directory. That means lib/ should be speed-optimized, whereas other parts should be size-optimized. We want to keep the same behavior, but do not want to parse board/*/config.mk again and again. We've got no choice but to invent a new method. CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED, if it is enabled, gives -O2 flag only for building under lib/ directory. Dirty codes which I had marked as "FIX ME" in board/${BOARD}/config.mk have been deleted. Instead, CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED has been defined in include/configs/${BOARD}.h.

* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

* Blackfin: bf537-stamp: drop board reset workaroundMike Frysinger2012-02-12-7/+0
| | | | | | | | | The bf537-stamp shouldn't need this SPI flash workaround. It was added by accident a long time ago through a convoluted series of steps which originated from a customer board (not the bf537-stamp). So drop it to keep people from incorrectly adding it to their own boards. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* punt unused clean/distclean targetsMike Frysinger2011-10-15-6/+0
| | | | | | | | | | 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>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-1/+1
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* Blackfin: move CONFIG_BFIN_CPU to board config.mkMike Frysinger2010-10-02-0/+2
| | | | | | | | | The CONFIG_BFIN_CPU option is largely used in the build system, so move it out of the board config.h and into the board config.mk. It'd be nice to keep everything in the config.h, but the patch to extract that value early was rejected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: bf537-stamp: use common spi boot workaround codeMike Frysinger2010-07-05-5/+2

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser2010-04-13-1/+1
| | | | | | | | | | The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Rename lib_generic/ to lib/Peter Tyser2010-04-13-2/+2
| | | | | | | | Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Change directory-specific CFLAGS to use full pathPeter Tyser2010-04-13-1/+1
| | | | | | | | | | | | | | | | | | Previously, a specific file or directory could be compiled with custom CFLAGS by adding a Makefile variable such as: CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c> or CFLAGS_lib = <custom flags for lib directory> This method breaks down once multiple files or directories share the same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>. This change allows finer grained control which we need once we move lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this change all lib/ directories would share the same custom CFLAGS.

* Blackfin: kill off useless initdram() usageMike Frysinger2010-01-17-7/+0

* Blackfin: enable -O2 in lib_generic/ for ADI/Bluetechnix boardsMike Frysinger2009-06-15-0/+3
| | | | | | | Building the compression code in lib_generic/ with -O2 rather than -Os gives a nice speed boost without too much code size increase. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify u-boot linker scriptsMike Frysinger2009-06-14-150/+1
| | | | | | | | | | | All the Blackfin linker scripts were duplicated across the board dirs with no difference save from the semi-often used ENV_IS_EMBEDDED option. So unify all of them in the lib_blackfin/ dir and for the few boards that need to embedded the environment directly, add a LDS_BOARD_TEXT define for them to customize via their board config file. This is much simpler than forcing them to duplicate the rest of the linker script. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* General help message cleanupWolfgang Denk2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
