Author: jhibbits Date: Wed Jun 14 04:26:37 2017 New Revision: 319936 URL: https://svnweb.freebsd.org/changeset/base/319936
Log: Actually add the mpc85xx_get_platform_clock() function. Follow up r319935 by actually committing the mpc85xx_get_platform_clock() function. This function was created to facilitate other development, and I thought I had committed it earlier. Some blocks depend on the platform clock rather than the system clock. The System clock is derived from the platform clock as one-half the platform clock. Rewrite mpc85xx_get_system_clock() to use the new function.
