Stefan Roese 916ed9444d ppc4xx: Canyonlands: Change EBC bus config to drive always (no high-z) ... This patch fixes a problem only seen very occasionally on Canyonlands. The NOR flash interface (CFI driver) doesn't work reliably in all cases. Erasing and/or programming sometimes doesn't work. Sometimes with an error message, like "flash not erased" when trying to program an area that should have just been erased. And sometimes without any error messages. As mentioned above, this problem was only seen rarely and with some PLL configuration (CPU speed, EBC speed). Now I spotted this problem a few times, when running my Canyonlands with the following setup (chip_config): 1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100 Changing the EBC configuration to not release the bus into high impedance state inbetween the transfers (ATC, DTC and CTC bits set to 1 in EBC0_CFG) seems to fix this problem. I haven't seen any failure anymore with this patch applied.
