From edb47d612fe9ddca77cd583f14c71517f065405f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Sun, 9 Oct 2022 21:38:25 +0200 Subject: [PATCH] Nokia RX-51: Fix double space key press MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Space key is indicated by two different bits. Some HW models indicate press of space key only by the first bit. Qemu indicates it by both bits at the same time, which is currently interpreted by u-boot as double key press. Fix this issue by setting first bit when only second is set (to support HW models which indicate press only by second bit) and always clearing second bit before processing to not report double space key press.
