Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

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

2010-10-18T20:07:10+00:00

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.

config.mk: avoid -traditional-cpp on OS X 10.5

2010-08-08T23:11:58+00:00

Simply trying to include a basic header file like stdlib.h on OS X 10.5
and then building with -traditional-cpp fails with lots of errors like:
In file included from /usr/include/stdlib.h:63,
                 from test.c:3:
/usr/include/available.h:85: error: stray '#' in program
/usr/include/available.h:85: error: syntax error before numeric constant
/usr/include/available.h:86: error: stray '#' in program

In the past, I hadn't noticed because the old logic for these flags were
restricted to Darwin running on PowerPC systems while I'm running on an
Intel system.  But after some recent clean ups and changes, the flag was
being applied to all Darwin systems and my host tools broke.

nios: remove nios-32 arch

The nios-32 arch is obsolete and broken. So it is removed.

config.mk: use different host compiler for OS X 10.6

2010-05-26T20:31:55+00:00

Compiling tools subdirectory on Mac OS X 10.6 (Snow Leopard) complains about
wrong syntax in system includes.

In file included from /usr/include/stdio.h:444,
                 from ../source/u-boot/include/compiler.h:26,
                 from ../source/u-boot/lib/crc32.c:15:
/usr/include/secure/_stdio.h:46: error: syntax error in macro parameter list

This can be fixed by reverting the workaround for prior OS X releases in
config.mk conditionally for OS X 10.6+.

Move lib_$ARCH directories to arch/$ARCH/lib

2010-04-13T07:13:03+00:00

Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk

This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.

Change directory-specific CFLAGS to use full path

2010-04-13T07:13:00+00:00

Previously, a specific file or directory could be compiled with custom
CFLAGS by adding a Makefile variable such as:
  CFLAGS_dlmalloc.o = 
or
  CFLAGS_lib = 

This method breaks down once multiple files or directories share the
same path.  Eg FLAGS_fileA =  would incorrectly result in
both dir1/fileA.c and dir2/fileA.c being compiled with .

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.

Create CPUDIR variable

2010-04-13T07:12:59+00:00

The CPUDIR variable points to the location of a target's CPU directory.
Currently, it is set to cpu/$CPU.  However, using $CPUDIR will allow for
more flexibility in the future.  It lays the groundwork for reorganizing
U-Boot's directory structure to support a layout such as:

  arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types)
  arch/$ARCH/cpu/*      (architecture with one CPU type)
