From 41afb1dfad4d6af0c716746f6a15f3230482955c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 29 Jun 2018 22:31:13 +0300 Subject: [PATCH] x86/platform/intel-mid: Remove per platform code After custom TSC calibration gone, there is no more reason to have custom platform code for each of Intel MID. Thus, remove it for good. Signed-off-by: Andy Shevchenko Signed-off-by: Thomas Gleixner Cc: "H.
