- * setup.S Copyright (C) 1991, 1992 Linus Torvalds
- *
- * setup.s is responsible for getting the system data from the BIOS,
- * and putting them into the appropriate places in system memory.
- * both setup.s and system has been loaded by the bootblock.
- *
- * This code asks the bios for memory/disk/other parameters, and
- * puts them in a "safe" place: 0x90000-0x901FF, ie where the
- * boot-block used to be. It is then up to the protected mode
- * system to read them from there before the area is overwritten
- * for buffer-blocks.
- *
- * Move PS/2 aux init code to psaux.c
- * (troyer@saifr00.cfsat.Honeywell.COM) 03Oct92
- *
- * some changes and additional features by Christoph Niemann,
- * March 1993/June 1994 (Christoph.Niemann@linux.org)
- *
- * add APM BIOS checking by Stephen Rothwell, May 1994
- * (sfr@canb.auug.org.au)
- *
- * High load stuff, initrd support and position independency
- * by Hans Lermen & Werner Almesberger, February 1996
- * <lermen@elserv.ffm.fgan.de>, <almesber@lrc.epfl.ch>
- *
- * Video handling moved to video.S by Martin Mares, March 1996
- * <mj@k332.feld.cvut.cz>
- *
- * Extended memory detection scheme retwiddled by orc@pell.chi.il.us (david
- * parsons) to avoid loadlin confusion, July 1997
- *
- * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.
- * <stiker@northlink.com>
- *
- * Fix to work around buggy BIOSes which don't use carry bit correctly
- * and/or report extended memory in CX/DX for e801h memory size detection
- * call. As a result the kernel got wrong figures. The int15/e801h docs
- * from Ralf Brown interrupt list seem to indicate AX/BX should be used
- * anyway. So to avoid breaking many machines (presumably there was a reason
- * to orginally use CX/DX instead of AX/BX), we do a kludge to see
- * if CX/DX have been changed in the e801 call and if so use AX/BX .
- * Michael Miller, April 2001 <michaelm@mjmm.org>
- *
- * New A20 code ported from SYSLINUX by H. Peter Anvin. AMD Elan bugfixes

- * olpcpci.c - Low-level PCI config space access for OLPC systems
- * without the VSA PCI virtualization software.
- *
- * The AMD Geode chipset (GX2 processor, cs5536 I/O companion device)
- * has some I/O functions (display, southbridge, sound, USB HCIs, etc)
- * that more or less behave like PCI devices, but the hardware doesn't
- * directly implement the PCI configuration space headers. AMD provides
- * "VSA" (Virtual System Architecture) software that emulates PCI config
- * space for these devices, by trapping I/O accesses to PCI config register
- * (CF8/CFC) and running some code in System Management Mode interrupt state.
- * On the OLPC platform, we don't want to use that VSA code because
- * (a) it slows down suspend/resume, and (b) recompiling it requires special
- * compilers that are hard to get. So instead of letting the complex VSA
- * code simulate the PCI config registers for the on-chip devices, we
- * just simulate them the easy way, by inserting the code into the
- * pci_write_config and pci_read_config path. Most of the config registers
