From 591933ca6eabc440e6ed6967233aaf56fce464a3 Mon Sep 17 00:00:00 2001 From: James Yang Date: Fri, 8 Feb 2008 16:44:53 -0600 Subject: [PATCH] 85xx: get_tbclk() speed up and rounding fix Speed up get_tbclk() by referencing pre-computed bus clock frequency value from global data instead of sys_info_t. Fix rounding of result to nearest; previously it was rounding upwards.
