* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-72/+0
| | | | | | | | | 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 Tyser2010-04-13-1/+1
| | | | | | | | | | | | 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>
* Blackfin: link with normal ABI targetMike Frysinger2010-04-07-2/+2
| | | | | | | | | If someone uses the FDPIC toolchain to compile U-Boot, make sure the linker knows to use the normal ABI target rather than the FDPIC one. This wasn't needed with older toolchains, but when we fixed the linker such that the default target changed based on tuple, this broke. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: tweak embedded LDR env config optionMike Frysinger2010-01-17-3/+7
| | | | | | | Use the common config option for extracting the environment for embedding into LDR files and clarify the LDR-specific option. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* push LOAD_ADDR out to arch mk filesMike Frysinger2009-09-04-0/+2
| | | | | | | | | | Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: change global data register from P5 to P3Robin Getz2009-09-02-1/+1
| | | | | | | | | | | Since the Blackfin ABI favors higher scratch registers by default, use the last scratch register (P3) for global data rather than the first (P5). This allows the compiler's register allocator to use higher number scratch P registers, which in turn better matches the Blackfin instruction set, which reduces the size of U-Boot by more than 1024 bytes...

* Blackfin: use common code to preprocess linker scriptMike Frysinger2009-08-23-1/+1
| | | | | | | Now that the common code preprocesses the linker script, the Blackfin code no longer needs to do it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Move architecture specific config.mk files into subdirsPeter Tyser2009-07-21-0/+66
This cleans up U-Boot's toplevel directory a bit and makes the architecture 'config.mk' file naming and location similar to board and cpu 'config.mk' files Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
