changes for v3:
- dump config.mk, aligned to comment of Wolfgang Denk;
- split one configuration file to two, one is for RCW, one is for PBI
commands, add second entry in mkimage for second configuration file, aligned to comment of Wood Scott; 3. refined the README.pblimage;
Makefile | 6 + board/freescale/corenet_ds/pbi.cfg | 51 ++++++ board/freescale/corenet_ds/rcw.cfg | 32 ++++
If I apply this patch, and then run:
make P5020DS_SDCARD_config make u-boot.pbl
And then follow the instructions from the README:
2). Boot from SD/MMC Write u-boot.pbl to SD/MMC from offset 0x1000. =>tftp 100000 u-boot.pbl =>mmcinfo =>mmc write 100000 8 441 Change SW1[1:5] = off off on on off.
Will it work?
If I replace the word P5020DS with P3041DS, will it still work?
What I'm trying to figure out is whether rcw.cfg and pbi.cfg are truly generic for all 3 systems this patch claims support for, or if I have to replace them with different versions for those P* systems. My guess is that the rcw.cfg needs to be changed, but I wanted to check. If it needs to be changed, then what we need is something like rcw_p5020ds.cfg, rcw_p4080ds.cfg, rcw_p3041.cfg.
