Fixes for detailed boot, made cttz and ctlz instructions more compact,
and started cleaning up config files. arch/alpha/isa_desc: Made implementation of cttz and ctlz more compact base/remote_gdb.cc: Added comment about PALcode debugger accesses dev/baddev.cc: dev/baddev.hh: dev/ide_ctrl.cc: dev/ide_ctrl.hh: dev/pciconfigall.cc: dev/pciconfigall.hh: dev/tsunami_cchip.cc: dev/tsunami_cchip.hh: dev/tsunami_io.cc: dev/tsunami_io.hh: dev/tsunami_pchip.cc: dev/tsunami_pchip.hh: dev/tsunami_uart.cc: dev/tsunami_uart.hh: Cleaned up includes and changed device from FunctionalMemory to PioDevice for detailed boot dev/ns_gige.cc: The ethernet dev uses two BARs, and the first bars size was being set incorrectly. dev/tsunamireg.h: I don't know why we were using the superpage as the PCI memory addr. Changed and works correctly with detailed boot. --HG-- extra : convert_revision : b535e76612cb90b544305dc1aa8c5e0e774564bd
