++ * 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

++ * March 1993/June 1994 (Christoph.Niemann@linux.org)

++ * 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 .

++ * 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 2X Program is an extension of Program Operation.
++ Since the device is equipped with two DataRAMs, and two-plane NAND
++ Flash memory array, these two component enables simultaneous program
++ of 4KiB. Plane1 has only even blocks such as block0, block2, block4
++ while Plane2 has only odd blocks such as block1, block3, block5.
++ So MTD regards it as 4KiB page size and 256KiB block size
++
