Leah Rowe cc2f08e7bb Revert "coreboot: rev 8b52167a9f 13 July 2025, rebase t480"
This reverts commit 32dfdfbb01.

The update caused an issue on T480:

Backlight comes on, then off, then on, then off, repeatedly, and
never gets to the payload. Will have to investigate further.

Subject: [PATCH 02/41] lenovo/t400: Enable all SATA ports
There are 2 SATA ports on the chassis of t400(s), but at least one dock for
t400 contains a port for (P/S)ATA device, and t400s has a eSATA port on its
chassis, and another one on its dock.
They have to be unmasked via device tree to use.
This patch unmasked all SATA ports found within t400s with factory firmware.
