Author: raj Date: Thu Jan 8 18:31:43 2009 New Revision: 186909 URL: http://svn.freebsd.org/changeset/base/186909 Log: Improve and extend Marvell SOCs platform code. - Allow for setting per platform MPP/GPIO configuration in the kernel, so that we can override all settings firmware might set. - Set decode windows for the remaining on-chip peripherals: CESA, SATA and XOR. - Improve handling of USB controllers so that all port are available on the given SOC/platform (e.g. up to three on DB-78xxx), this includes rework of USB decode windows set-up. - Other minor fixes and cosmetics.
