From: Bin Meng Date: Wed, 28 Jul 2021 04:00:23 +0000 (+0800) Subject: x86: dts: Define a default TSC timer frequency X-Git-Url: http://git.dujemihanovic.xyz/projects?a=commitdiff_plain;h=c79cbb5952068d9f05e4bcc7bdbbc8957fe35c68;p=u-boot.git x86: dts: Define a default TSC timer frequency If for some reason, TSC timer frequency cannot be determined from hardware, nor is it specified in the device tree, U-Boot will panic resulting in endless reset during boot. Let's define a default TSC timer frequency using the Kconfig value CONFIG_X86_TSC_TIMER_FREQ (note: #include must be used instead of /include/ otherwise the macro is not pre-processed).
