      Add board MAINTAINERS files · 93d4334f
      Masahiro Yamada authored
      We have switched to Kconfig and the boards.cfg file is going to
      be removed. We have to retrieve the board status and maintainers
      information from it.
      
      The MAINTAINERS format as in Linux Kernel would be nice
      because we can crib the scripts/get_maintainer.pl script.
      
      After some discussion, we chose to put a MAINTAINERS file under each
      board directory, not the top-level one because we want to collect
      relevant information for a board into a single place.
      
      TODO:
      Modify get_maintainer.pl to scan multiple MAINTAINERS files.

      kconfig: add board Kconfig and defconfig files · dd84058d
      Masahiro Yamada authored
      This commit adds:
       - arch/${ARCH}/Kconfig
          provide a menu to select target boards
       - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
          set CONFIG macros to the appropriate values for each board
       - configs/${TARGET_BOARD}_defconfig
          default setting of each board
      
      (This commit was automatically generated by a conversion script
      based on boards.cfg)
      
      In Linux Kernel, defconfig files are located under
      arch/${ARCH}/configs/ directory.
      It works in Linux Kernel since ARCH is always given from the
      command line for cross compile.
      
      But in U-Boot, ARCH is not given from the command line.
      Which means we cannot know ARCH until the board configuration is done.
      That is why all the "*_defconfig" files should be gathered into a
      single directory ./configs/.

      kbuild, blackfin: Add CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED · e91df49f
      Masahiro Yamada authored
      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 scripts · 6825a95b
      Masahiro Yamada authored
      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.

      Switch from archive libraries to partial linking · 6d8962e8
      Sebastien Carlier authored
      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.

      Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE · 14d0a02a
      Wolfgang Denk authored
      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.

      Make sure that argv[] argument pointers are not modified. · 54841ab5
      Wolfgang Denk authored
      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>" · 61f2b38a

      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.

      Change directory-specific CFLAGS to use full path · 89f39e17
      Peter Tyser authored
      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.

      General help message cleanup · a89c33db
      Wolfgang Denk authored
      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
