* powerpc/85xx: Modify NAND loader makefiles to compile NAND_SPL linker scriptDipen Dudhat2011-04-15-4/+7
| | | | | | | | | Modify eLBC based platform's NAND loader Makefile to preprocess nand loader linker script and then use it. Signed-off-by: Dipen Dudhat <Dipen.Dudhat@freescale.com> CC: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Fix build issues cause by LDFLAGS_FINAL changesWolfgang Denk2011-03-31-3/+3
| | | | | | | | | | | Commit 6dc1ece "Introduce a new linker flag LDFLAGS_FINAL" modified a number of Makefiles in a way that broke out-of-tree builds. The problem was that $(nandobj) was used before it got defined. Fix this. Signed-off-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Introduce a new linker flag LDFLAGS_FINALHaiying Wang2011-03-22-1/+2
| | | | | | | | | | | | | | | 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.

* powerpc/85xx: add CONFIG_SYS_TEXT_BASE_SPL for 85xx nand spl buildHaiying Wang2010-11-12-2/+2
| | | | | | | | | | Introduce a SPL specific CONFIG_SYS_TEXT_BASE_SPL define to be used by the linker. This has similiar semantics to CONFIG_SYS_TEXT_BASE however since SPL is a unqiue image we introduce a new variable to control its text base address.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-2/+2
| | | | | | | | | | | | 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.

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-6/+6
| | | | | | | | | | | | | | | | | 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.

* Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser2010-04-13-1/+1
| | | | | | | | | | The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-1/+1
| | | | | | | | | Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Create CPUDIR variablePeter Tyser2010-04-13-2/+2
| | | | | | | | | | | | The CPUDIR variable points to the location of a target's CPU directory. Currently, it is set to cpu/$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) Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
