From 22ef1439dd6d3844c548367964238c963593f95a Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Fri, 22 Apr 2022 16:48:47 -0600 Subject: mb/google/zork: Correct PIRQ_MISC0 configuration The current configuration is masking off IRQ 1 and IRQ 12 to the PIC. This for some reason causes problems when using level triggered interrupts. This change updates the PIRQ_MISC0 value to match what skyrim is doing. This will enable level interrupts to work correctly. BUG=b:218874489, b:160595155 TEST=Boot zork and verify keyboard still works. Boot with patch train and verify keyboard works as expected.
