* Blackfin: unify u-boot linker scriptsMike Frysinger2009-06-14-152/+0
| | | | | | | | | | | All the Blackfin linker scripts were duplicated across the board dirs with no difference save from the semi-often used ENV_IS_EMBEDDED option. So unify all of them in the lib_blackfin/ dir and for the few boards that need to embedded the environment directly, add a LDS_BOARD_TEXT define for them to customize via their board config file. This is much simpler than forcing them to duplicate the rest of the linker script. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix booting with older bootroms (no EVT1)Mike Frysinger2009-05-06-1/+8
| | | | | | | | | | | When dropping jump block support, the assumption was that all bootroms supported entry point redirection via the EVT1 register. Unfortunately, this turned out to be incorrect for the oldest Blackfin parts (BF533-0.2 and older and BF561). No one really noticed earlier because these parts usually are booted by bypassing the bootrom entirely, and older BF533 parts are not supported at all (too many anomalies).

* Blackfin: kill off LDR jump blockMike Frysinger2009-03-23-3/+2
| | | | | | | The Boot ROM uses EVT1 as the entry point so set that rather than having to use a tiny jump block in the default EVT1 location. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix linker scripts to work with --gc-sectionsMike Frysinger2009-01-07-10/+13
| | | | | | | Make sure all .text sections get pulled in and the entry point is properly referenced so they don't get discarded when linking with --gc-sections. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: linker scripts: force start.o and set initcode boundariesMike Frysinger2008-10-23-1/+6
| | | | | | | | Make sure that the start.o object is always the first object in our linker script regardless of configuration settings, and add some linker symbols so the ldr utility can properly locate the initcode when generating a LDR. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: unify cpu and boot modesMike Frysinger2008-03-30-112/+97
| | | | | | | | All of the duplicated code for Blackfin processors and boot modes have been unified. After all, the core is the same for all processors, just the peripheral set differs (which gets handled in the drivers). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
