unify version_string

2011-07-28T15:22:53+00:00

This patch removes the architecture specific implementation of
version_string where possible. Some architectures use a special place
and therefore we provide U_BOOT_VERSION_STRING definition and a common
weak symbol version_string.

nios2: Make STANDALONE_LOAD_ADDR configurable per board

2011-05-17T01:00:43+00:00

Follow commit 8ae86b76c648d8bef97241c78e2fddb1c4f164d3
which changed the variable name.

Fix this error,

Handle most LDSCRIPT setting centrally

2011-04-29T22:59:47+00:00

Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk.  Some
are found using an arch-specific rule for looking in CPUDIR, etc.

Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.

Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.

If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.

If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:

$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds

Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules.  These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

rename _end to __bss_end__

2011-03-27T17:18:37+00:00

Currently, _end is used for end of BSS section.  We want _end to mean
end of u-boot image, so we rename _end to __bss_end__ first.

Introduce a new linker flag LDFLAGS_FINAL

2011-03-22T22:32:06+00:00

commit 8aba9dceebb14144e07d19593111ee3a999c37fc
Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS

breaks the usage of --gc-section to build nand_spl. We still need linker option
--gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes
the --gc-sections to each uboot image.

To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace
PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS

2011-01-25T21:22:30+00:00

Linker needs to use the proper endian/bfd flags even when doing partial linking.
LDFLAGS_u-boot sets linker option which is called it when U-boot is built
(u-boot final).
LDFLAGS sets necessary option by partial linking (use in cmd_link_o_target).
