From 815f2cf63a8f329144d3f46c7cf45b7f180f2436 Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Fri, 14 Apr 2017 19:37:14 +0200 Subject: [PATCH] UPSTREAM: mb/lenovo/t60: Remove PCI reset code from romstage Commit bf264e94 (i945:) adds a PCI reset to the romstage, and commit bc8613ec (Fix i945 based boards) fixes that to use the correct delay of 200 ms. This code was then copied over, when adding support for the Lenovo T60. The reset was related to the shipped crypto card on the Roda RK886EX and Kontron 986LCD-M, so is not needed on the Lenovo T60. So remove it, to reduce the boot time by 200 ms. The same change is done for the Lenovo X60 in commit 7676730b (mb/lenovo/x60: Remove PCI reset code from romstage).
