      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.

      Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value · 25ddd1fb
      Wolfgang Denk authored
      CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
      being able to use "sizeof(struct global_data)" in assembler files.
      Recent experience has shown that manual synchronization is not
      reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
      GENERATED_GBL_DATA_SIZE which gets automatically generated by the
      asm-offsets tool.  In the result, all definitions of this value can be
      deleted from the board config files.  We have to make sure that all
      files that reference such data include the new <asm-offsets.h> file.
      
      No other changes have been done yet, but it is obvious that similar
      changes / simplifications can be done for other, related macro
      definitions as well.

      Makefile: move all Power Architecture boards into boards.cfg · 2ae18241
      Wolfgang Denk authored
      Clean up Makefile, and drop a lot of the config.mk files on the way.
      
      We now also automatically pick all boards that are listed in
      boards.cfg (and with all configurations), so we can drop the redundant
      entries from MAKEALL to avoid building these twice.

      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) {
      			...

      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

      Change initdram() return type to phys_size_t · 9973e3c6
      Becky Bruce authored
      This patch changes the return type of initdram() from long int to phys_size_t.
      This is required for a couple of reasons: long int limits the amount of dram
      to 2GB, and u-boot in general is moving over to phys_size_t to represent the
      size of physical memory.  phys_size_t is defined as an unsigned long on almost
      all current platforms.
      
      This patch *only* changes the return type of the initdram function (in
      include/common.h, as well as in each board's implementation of initdram).  It
      does not actually modify the code inside the function on any of the platforms;
      platforms which wish to support more than 2GB of DRAM will need to modify
      their initdram() function code.
      
      Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
      MPC8641HPCN.

      Big white-space cleanup. · 53677ef1
      Wolfgang Denk authored
      This commit gets rid of a huge amount of silly white-space issues.
      Especially, all sequences of SPACEs followed by TAB characters get
      removed (unless they appear in print statements).
      
      Also remove all embedded "vim:" and "vi:" statements which hide
      indentation problems.

      Add support for a saving build objects in a separate directory. · f9328639
      Marian Balakowicz authored
      Modifications are based on the linux kernel approach and
      support two use cases:
      
        1) Add O= to the make command line
        'make O=/tmp/build all'
      
        2) Set environement variable BUILD_DIR to point to the desired location
        'export BUILD_DIR=/tmp/build'
        'make'
      
      The second approach can also be used with a MAKEALL script
      'export BUILD_DIR=/tmp/build'
      './MAKEALL'
      
      Command line 'O=' setting overrides BUILD_DIR environent variable.
      
      When none of the above methods is used the local build is performed and
      the object files are placed in the source directory.
