From 727a224aedfb3d7d01aa5e165f6801b026e1fafa Mon Sep 17 00:00:00 2001 From: Felix Held Date: Wed, 16 Feb 2022 16:15:46 +0100 Subject: amd/common/block/gpio/gpio: don't use -1 as bitmask in gpio_or32 The and-mask passed to the gpio_update32 call needs all 32 bits to be set to ones. When building as 32 bit binary the -1UL will result in the needed bit mask, but for a 64 bit build the constant would have 64 bits set to ones which then gets truncated to 32 bits causing a compiler error. Use 0xffffffff as bit mask instead which behaves correctly in both cases and also clarifies what this is doing. TEST=Timeless build for Chausie results in identical image.
