Hello, all. This humongous patchset modularizes SFF support and cleans up whole lot of other stuff in the course. At the end, core layer is leaner and simpler, SFF support is well modularized and made optional and LLDs don't have to worry about how it's gonna meet the pseudo SFFism libata used to require. This patchset is comprised of the following 27 patches. 0001-libata-drop-ata_dev_select-from-ata_dev_read_id.patch 0002-libata-reorder-functions-in-libata-sff.c.patch 0003-libata-reorganize-SFF-related-stuff.patch 0004-libata-move-ata_pci_default_filter-out-of-CONFIG_.patch 0005-libata-kill-ata_chk_status-call-from-ata_dev_conf.patch 0006-libata-kill-ata_chk_status.patch 0007-libata-rename-SFF-functions.patch 0008-libata-rename-SFF-port-ops.patch 0009-libata-clean-up-port_ops-sff_irq_clear.patch 0010-libata-separate-out-ata_std_prereset-from-ata_sff.patch 0011-libata-separate-out-ata_std_postreset-from-ata_sf.patch 0012-libata-restructure-SFF-post-reset-readiness-waits.patch 0013-libata-separate-out-ata_wait_ready-and-implement.patch 0014-ahci-use-ata_wait_after_reset-instead-of-ata_sff_.patch 0015-libata-move-generic-hardreset-code-from-sata_sff_ha.patch 0016-libata-implement-and-use-sata_std_hardreset.patch 0017-libata-clear-SError-after-link-resume.patch 0018-libata-move-PMP-SCR-access-failure-during-reset-to.patch 0019-libata-unify-mechanism-to-request-follow-up-SRST.patch 0020-libata-add-qc_fill_rtf-port-operation.patch 0021-libata-drop-finish_qc-from-ata_qc_complete_multipl.patch 0022-libata-replace-tf_read-with-qc_fill_rtf-for-non-SFF.patch 0023-libata-remove-check_status-from-non-SFF-drivers.patch 0024-libata-kill-ata_noop_dev_select.patch 0025-libata-clean-up-dummy-port_ops.patch 0026-libata-don-t-use-ap-ioaddr-in-non-SFF-drivers.patch 0027-libata-make-SFF-support-optional.patch 0001-0006 prepare for the soon-to-follow changes by dropping unncessary stuff and reorganizing code. 0007-0008 mass renames SFF related stuff. Over the time, the naming has become quite chaotic. Core and SFF stuff are mixed and various prefixes are in use pseudo-randomly. These two patches make the names consistent. By doing so make it clear which belongs where - ie. it sets the requirements for the soon-to-follow modularization. Stuff named with SFF and BMDMA prefixes should only live in libata-sff.c and can't be directly referenced from core layer. 0009-0011 separate out SFF specific parts regarding ->sff_irq_clear, prereset and postreset. 0012-0019 refactor post-reset wait code, separate out SFF specific parts regarding resets and clean up resulting code. 0020-0023 separate out TF access code out of core layer. 0024-0026 separate out what's left of SFF from core layer. 0027 makes SFF support optional. The patchset has been tested on the following LLDs. ahci, ata_piix, sata_sil, sata_sil24, pdc_adma, pata_hpt366, sata_promise, pata_jmicron sata_fsl, ipr and libsas received good amount of modification but I couldn't test them. Especially, I couldn't even compile test sata_fsl. If you have access to the above drivers, please verify they are okay. On x86_64 w/o any debugging turned on, on-disk size of libata.ko is reduced from 226k to 193k if SFF is turned off. The loaded size is changed from 157k to 133k.
