* Add the VLSI SuperCore and Wildcat chipsets * Disable logging and minor cleanups * Add the AST Bravo MS P/90 (Rattler) * Add the AT&T Globalyst 620 (NCR 3248) * Add the DEC Celebris 5xx * Add the DFI G586VPM Rev C * Add the Packard Bell PB600 * Fix southbridge PCI Command Register writes * Block the Cyrix 6x86 on incompatible machines * Rename the AT&T Globalyst 620 to include the names of the NCR counterparts * Add the Zeos Pantera Wildcat * Add RZ-1001 variant of the RZ-1000 PCI IDE controller and made the Zeos Pantera Wildcat use it * Add the Micronics M54Si * Update machine_table.c * Re-add new machines to machine table * Update machine inits to use new KBC device names * Use correct machine init method as NVRAM init is done by the chipset code * Use a Phoenix KBC for the AST Bravo since the BIOS calls command D5h to show the KBC revision * Update KBC comments in machine table * Update VLSI 59x chipset comments * Update machine inits for new super I/O code * Reorganize machines and update comments * AST readout device actually has multiple indexed registers * Implement the AST Bravo MS ECP DMA configuration * Implement jumpered/hardwired ECP DMA for the remaining machines * Fix ECP DMA on the AST Bravo MS * Move the DEC Celebris to the Socket 4/5 category * Implement SMI I/O port read, fixes APM init on AT&T, Micronics and Zeos machines * Convert AST readout device to new logging system * Update KBC init to new method * Cleanups
