Niklas Cassel 7edbb60592 ahci: clean up intel_pcs_quirk ... The comment in front of board_ahci_pcs7 is completely wrong. It claims that board_ahci_pcs7 is needing the quirk, but in fact, the logic implemented in ahci_intel_pcs_quirk() is the exact opposite, only board_ahci_pcs7 is _excluded_ from the quirk. This way of implementing a quirk is unconventional in several ways: First of all because it has a board ID for which the quirk should _not_ be applied (board_ahci_pcs7), instead of the usual way where we have a board ID for which the quirk should be applied. The second reason is that other than only excluding board_ahci_pcs7 from the quirk, PCI devices that make use of the generic entry in ahci_pci_tbl (which matches on AHCI class code) are also excluded. This can of course lead to very subtle breakage, and did indeed do so in: commit 104ff59af7 ("ata: ahci: Add Tiger Lake UP{3,4} AHCI controller"), which added an explicit entry with board_ahci_low_power to ahci_pci_tbl. This caused many users to complain that their SATA drives disappeared. The logical assumption was of course that the issue was related to LPM, and was therefore reverted in commit 6210038aea ("ata: ahci: Revert "ata: ahci: Add Tiger Lake UP{3,4} AHCI controller""). It took a lot of time to figure out that this was all completely unrelated to LPM, and was instead caused by an unconventional Intel quirk. Clean up the quirk so that it behaves like other quirks, i.e. define a board where the quirk is applied. Platforms that were using board_ahci_pcs7 are converted to use board_ahci, this is safe since the boards were identical, and board_ahci_pcs7 did not define any custom port_ops. This way, new Intel platforms can be added using the correct "board_ahci" board, without getting any unexpected quirks applied. This means that we currently have some modern platforms defined that are using the Intel PCS quirk, but that is identical to the behavior that was there before this commit. No functional changes intended.
