From a5e93651fb91d8ae38e4f16a1ca7495ae257f2b9 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 19 Jun 2014 17:31:36 +0800 Subject: [PATCH] samus: Remove PP1800_PGOOD check The PP1800_PGOOD pullup resistor was no-stuff on P2B boards so the input value is floating and cannot be relied on for proper sequencing. Before P2B it was always pulled up so it was not a useful signal to wait on anyways.
