mb/lenovo/t520: Disable SATA2 and Thermal on W520
If a discoverable device (e.g. a PCI device) does not appear in the devicetree (typically because it is removable), coreboot enables it by default. Disable the SATA2 (device for SATA ports 4 and 5, which is not used in AHCI mode) and Thermal devices on W520 as well. Both devices were only disabled on the T520. Tested, this change fixes a long boot time when using MrChromebox's edk2 payload on the W520, likely related to the following errors: AHCI: Error interrupt reported PxIS: 40000001 Non data transfer failed at retry 0 AHCI: Error interrupt reported PxIS: 40000001 Non data transfer failed at retry 1 AHCI: Error interrupt reported PxIS: 40000001 Non data transfer failed at retry 2 AHCI: Error interrupt reported PxIS: 40000001 Non data transfer failed at retry 3 AHCI: Error interrupt reported PxIS: 40000001 Non data transfer failed at retry 4 Change-Id: I0b0483aae05fa84d97987a93db634b740f830e18 Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/71857 Reviewed-by: Paul Menzel <paulepanter@mailbox.org> Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
