This patch disables deprecated IDE subsystem in assabet_defconfig (no IDE host drivers are selected in this config so there is no valid reason to enable IDE subsystem itself). Cc: Dmitry Eremin-Solenikov <redacted> Signed-off-by: Bartlomiej Zolnierkiewicz <redacted>I think the series makes a lot of sense. I have checked your assertions in the changelogs and found no flaws in your logic, so I think we should take them all through arm-soc unless there are other concerns.Thank you. Should I resend everything or just patches that were not reposted yet (the ones that were marked as RFT initially and got no feedback)?I'd be fine with just getting a pull request with all the patches that had no negative feedback and that were not already applied (if any).Here it is (sorry for taking so long).I've just been digging in the dmesg logs from when I was using the Assabet+Neponset as my firewall, and it was having to use the IDE ide-cs driver rather than the pata pcmcia driver. I don't recall whether the pata pcmcia driver was a problem or not, as the PCMCIA interface can't cope with _any_ 32-bit accesses. I think PATA tries to use the "highest" possible access size by default...
It doesn't actually - it defaults to 16-bits for PIO data access and you must explicitly enable 32-bits using ATA_PFLAG_PIO32 port flag (pata_pcmcia doesn't set it so it should be okay). Also taskfile registers are accessed using 8-bits access by default transport functions (which are used by pata_pcmcia).
