crt0.S.lb: Modified so that it is safe to include console.inc console.c: Added print_debug_ and frieds which are non inline variants of the normal console functions div64.h: Only include limits.h if ULONG_MAX is not defined and define ULONG_MAX on ppc socket_754/Config.lb Conditionally set config chip.h socket_940.c We don't need and #if CONFIG_CHIP_NAME we won't be linked in if there are no references. slot_2/chip.h: The operations struct need to be spelled cpu_intelt_slot_2_ops slot_2/slot2.c: The same spelling fix socket_mPGA603/chip.h: again socket_mPGA603/socket_mPGA603_400Mhz.c: and again socket_mPGA604_533Mhz/Config.lb: Conditionally defing CONFIG_CHIP_NAME socket_mPGA604_800Mhz/chip.h: Another spelling fix socket_mPGA604_800Mhz.c and again via/model_centaur/model_centaur_init.c: It's not an intel CPU so don't worry about Intel microcode uptdates earlymtrr.c: Remove work around for older versions of romcc pci_ids.h: More ids. malloc.c: We don't need string.h any longer uart8250.c: Be consistent when delcaring functions static inline arima/hdama/mptable.c: Cleanup to be a little more consistent amdk8/coherent_ht.c: - Talk about nodes not cpus (In preparation for dual cores) - Remove clear_temp_row (as it is no longer needed) - Demoted the failure messages to spew. - Modified to gracefully handle failure (It should work now if cpus are removed) - Handle the non-SMP case in verify_mp_capabilities - Add clear_dead_routes which replaces clear_temp_row and does more - Reorganize setup_coherent_ht_domain to cleanly handle failure. - incoherent_ht.c: Clean up the indenation a little. i8259.c: remove blank lines at the start of the file. keyboard.c: Make pc_keyboard_init static ramtest.c: Add a print out limiter, and cleanup the printout a little. amd8111/Config.lb: Mention amd8111_smbus.c amd8111_usb.c: Call the structure usb_ops not smbus_ops. NSC/pc97307/chip.h: Fix spelling issue pc97307/superio.c: Use &ops no &pnp_ops. w83627hf/suerio.c: ditto w83627thf/suerio.c: ditto buildrom.c: Use braces around the body of a for loop. It's more maintainable. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1778 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
