From 1c105903078f85dd1be805c737b4e4da6dea0618 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Sun, 23 Dec 2018 07:22:59 +0200 Subject: [PATCH] arch/x86: Use a common timestamp.inc with romcc bootblocks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The same file was replicated three times for certain soc/intel bootblocks, yet there are no indications or need to do chipset-specific initialisation. There is no harm in storing the TSC values in MMX registers even when they would not be used.
