74xx_7xx/mpc86xx/ppmc7xx: Fix do_reset() declaration

2010-12-17T19:26:19Z

The following commit: commit 882b7d726febe65579d6502c271412ecb05821d7 Author: Mike Frysinger Date: Wed Oct 20 03:41:17 2010 -0400 do_reset: unify duplicate prototypes missed the 74xx_7xx and mpc86xx arches and the ppmc7xx board do_reset() functions which resulted in build errors such as: cpu.c:128: error: conflicting types for 'do_reset' include/command.h:102: error: previous declaration of 'do_reset' was here Signed-off-by: Peter Tyser

Remove redundant config.mk files

2010-12-09T09:25:56Z

Recent cleanup actions resulted in a number of config.mk files that contained only redundant entries like PLATFORM_CPPFLAGS += -I$(TOPDIR) or settings of variables that were not used anywhere in the code, like TEXT_END = 0xfe080000 Remove these unnecessary files.

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

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

Makefile: move all Power Architecture boards into boards.cfg

2010-10-18T20:12:04Z

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. Signed-off-by: Wolfgang Denk

Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

2010-10-18T20:07:10Z

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.

ppmc7xx: Use _start as reset entry point

2010-10-12T21:01:03Z

Previously the _warm_start label was used as an entry point. These 2 entry points should be functionally identical after the removal of the BOOTFLAG_WARM define. Signed-off-by: Peter Tyser

Make sure that argv[] argument pointers are not modified.

2010-07-04T21:55:42Z

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) { ...

Move arch/ppc to arch/powerpc

2010-04-21T21:42:38Z

As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
