      start a linker script helper file · 6ac9f479
      由 Mike Frysinger 提交于 
      Start a common header file for common linker script code (such as
workarounds for older linkers) rather than doing this in the build system.

As fallout, we no longer execute the linker every time config.mk is
included by a build file (which can easily be 70+ times), but rather only
execute it once.

This also fixes a bug in the major version checking by creating a macro to
easily compare versions and keep people from making the same common
mistake (forgetting to check major and minor together).

      mpc83xx: sbc8349 - make enabling PCI more user friendly · c0d660fb
      由 Paul Gortmaker 提交于 
      Prior to this commit, to enable PCI, you had to go manually
edit the board config header, which isn't really user friendly.
This adds the typical PCI make targets to the toplevel Makefile
in accordance with what is being done with other boards.

      Fix all linker scripts for older binutils versions (pre-2.16) · 1aada9cd
      由 Wolfgang Denk 提交于 
      Commit f62fb999 fixed handling of all rodata sections by using a
wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT()
and SORT_BY_NAME().  Unfortunately these functions were only
introduced with biunutils version 2.16, so the modification broke
building with all tool chains using older binutils.

This patch makes it work again.  This is done by omitting the use of
these functions for such old tool chains.  This will result in
slightly larger target binaries, as the rodata sections are no longer
in optimal order alignment-wise which reauls in unused gaps, but the
effect was found to be insignificant - especially compared to the fact
that you cannot build U-Boot at all in the current state.

As ld seems to have no support for conditionals we run the linker
script through the C preprocessor which can be easily used to remove
the unwanted function calls.

Note that the C preprocessor must be run with the "-ansi" (or a
"-std=") option to make sure all the system-specific predefined
macros outside the reserved namespace are suppressed. Otherise, cpp
might for example substitute "powerpc" to "1", thus corrupting for
example "OUTPUT_ARCH(powerpc)" etc.

      Make linking against libgcc configurable · 52b1bf2c
      由 Wolfgang Denk 提交于 
      Many (especially ARM) tool chains seem to come with broken or
otherwise unusable (for the purposes of builing U-Boot) run-time
support libraries `libgcc.a'. By using the "USE_PRIVATE_LIBGCC"
setting we allow to use alternative libraries instead.

"USE_PRIVATE_LIBGCC" can either be set as an environment variable in
the shell, or as a command line argument when running "make", i. e.
	$ make USE_PRIVATE_LIBGCC=yes
or
	$ USE_PRIVATE_LIBGCC=yes
	$ export USE_PRIVATE_LIBGCC
	$ make

The value of "USE_PRIVATE_LIBGCC" is the name of the directory which
contains the alternative run-time support library `libgcc.a'. The
special value "yes" selects the directory $(OBJTREE)/lib_$(ARCH) .

Note that not all architectures provide an alternative `libgcc.a' in
their lib_$(ARCH) directories - so far, only ARM does.

      push CROSS_COMPILE out to $(ARCH)_config.mk · 1ea6bcd8
      由 Mike Frysinger 提交于 
      Each arch should handle setting a proper default CROSS_COMPILE value in
their own config.mk file rather than having to maintain a large ugly list
in the Makefile.  By using conditional assignment, we don't have to worry
about the variable already being set (env/cmdline/etc...).

The common config.mk file takes care of exporting CROSS_COMPILE already,
and while a few variables (toolchain ones) utilize CROSS_COMPILE before
including the arch config.mk, they do so with deferred assignment.

      Remove legacy NAND and disk on chip code. · be33b046
      由 Scott Wood 提交于 
      Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.
