+ * 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
+ * are read-only anyway, so the bulk of the simulation is just table lookup.

- *
- * 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
- * are read-only anyway, so the bulk of the simulation is just table lookup.

++ * 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
++ * are read-only anyway, so the bulk of the simulation is just table lookup.

++ PromFS is a file system interface to various IEEE-1275 compatible
++ firmwares. If you have such a firmware (Sparc64, PowerPC, and
++ some other architectures and embedded systems have such firmwares,
++ with names like "OpenBoot (tm)" and "OpenFirmware"), say Y here
++ to be able to access the firmware's device-tree from Linux.
++
++ The firmware device-tree is available as a virtual file system,
++ can be mounted under /prom with the command "mount -t promfs
++ none /prom".
++
++ To compile PromFS support as a module, choose M here; the module
++ will be called promfs. If unsure, choose M.
++
++config RAMFS
++ bool
++ default y
++ ---help---
++ Ramfs is a file system which keeps all files in RAM. It allows
++ read and write access.
++
++ It is more of an programming example than a useable file system. If
++ you need a file system which lives in RAM with limit checking use
++ tmpfs.
++
++ To compile this as a module, choose M here: the module will be called
++ ramfs.
