From 80b2f2358485514cc31da2ee989e928288b80d5c Mon Sep 17 00:00:00 2001 From: Victor Ding Date: Thu, 18 Feb 2021 04:27:47 +0000 Subject: drivers/generic/bayhub_lv2: move the driver to ".enable" coreboot sets up certain configs (e.g. L1ss) based on the device's reported capacities; however, this BayHub lv2 driver modifies some of its capacities after coreboot uses them. Therefore, coreboot may make incorrect configs based on out-of-date capacities. This patch moves the driver from ".init" to ".enable" so that the capacities are set before the rest of coreboot queries them.
