+This is the documentation for the AMD Geode LX framebuffer driver.
+
+Kernel Build Configuration Parameters
+-------------------------------------
+These kernel build parameters are operated using "make xconfig" or
+"make menuconfig" from the kernel source root directory.
+The parameter path to these parameters is:
+Device Drivers
+ Graphics Support
+ Support for frame buffer devices
+ AMD Geode generic framebuffer support
+ AMD Geode LX framebuffer driver
+ AMD Geode LX console acceleration
+ AMD Geode Framebuffer panel support
+
+Config_Param Value Definition
+============ ===== ==========
+FB_GEODE (y/m/n) Build AMD Geode generic framebuffer support
+FB_GEODE_LX (y/n) Build AMD Geode LX framebuffer driver (selects CIMARRON)
+FB_GEODE_ACCEL (y/n) Build AMD Geode LX console acceleration
+FB_GEODE_PANEL (y/n) Build AMD Geode Framebuffer panel support
+
+
+Kernel Boot Command Line Argument Options
+-----------------------------------------
+If the geodefb driver has been built into the kernel (not as a module), then
+driver setup options are available via the kernel cmdline interface.
+
+kernel boot command line argument options are available using:
+video=geodefb:[, ...]
+option strings are one of three types:
+identifier as in video=geodefb:off
+identifier=value as in video=geodefb:vfreq=85
+noidenfier as in video=geodefb:noflatpanel
+
+video=option Definition
+============ ==========
+off - specify this option to disable the geodefb.
+vfreq= - specifies the default vertical refresh (default 60)
+vmode= - specifies a mode text string. (default = 640x480@60-16)
+no/compression - disables/enables compression display acceleration (default disabled)
+maxmem - Maximum amount of memory to use for the FB (default 12288K)
+no/accel - disables/enables rendering accelerations (default enabled)
+
+if the module was build with CONFIG_FB_GEODE_PANEL applied
+no/flatpanel - disable/enables flatpanel operation (default enabled)
+no/fphwscale - disable/enables flatpanel hardware scaling (default enabled)
+
+
+Module Parameters:
+------------------
+If geodefb was built as a module, then parameters can be applied
+when the modules is installed (via insmod/modprobe or modules.conf).
+When installing the module, new options are specified as follows:
+modprobe geodefb ... or
+insmod /path/geodefb.ko ...
+
+Module parameters:
+parameter Definition
+========= ==========
+vfreq - Set initial video refresh rate in cycles per second
+vmode - Set initial mode to x@refresh-bpp
+compression - Compression support (0=disabled or 1=enabled)
+maxmem - Maximum amount of memory to use for the FB (in Kbytes)
+accel - HW accleration support (0=disabled or 1=enabled)
+
+if the module was build with CONFIG_FB_GEODE_PANEL applied
+flatpanel - Flatpanel support (0=disabled or 1=enabled)
+fphwscale - FP Hardware Scaling (0=disabled or 1=enabled)
+
+
+Video Modes:
+------------
+The permissible mode parameter values are:
+geometry
+ 640x480, 800x600, 1024x768, 1152x864, 1280x1024, 1600x1200, 1920x1600
+refresh
+ 56, 60, 70, 72, 75, 85, 90, 100
+bpp
+ 8, 16, 32
+
+The permissible mode parameter combinations are defined by the cimarron
+driver, and in cimarron by cim_modes.c.
+
+
+Notes:
+-----
+Since building the geodefb normally select the cimarron driver, please
+review the procedures for building cimarron. To have the framebuffer
+driver work properly with X windows, it is normally necessary to create
+device nodes for /dev/cimarron and possibly links for /dev/videox.
+See cimarron module and lxv4l2 module documentation.

+Howto for Linux device driver for the AMD5536 USB Device Controller (UDC)
+for gadget driver stack
+-------------------------------------------------------------------------------
+
+Author: Thomas Dahlmann
+
+INTRODUCTION:
+
+The AMD5536 UDC is part of x86 southbridge AMD5536 and MIPS CPU Au1200.
+It is a DMA capable usb device controller. The usb port is shared
+between host and UDC. The on-chip UOC controller is used to switch the
+usb port between host, UDC and neutral. So amd5536uoc driver is needed
+to get the UDC operating.
+
+-------------------------------------------------------------------------------
+WHAT YOU NEED:
+-------------------------------------------------------------------------------
+
+copy/replace following files to /usr/src/linux/drivers/usb/gadget
+ amd5536udc.c
+ amd5536udc.h
+ amd5536uoc.c
+ amd5536uoc.h
+ ether.c
+ file_storage.c
+ zero.c
+ inode.c
+ gadget_chips.h
+ Makefile
+ Kconfig
+
+-------------------------------------------------------------------------------
+HOW TO INSTALL IT:
+-------------------------------------------------------------------------------
+
+change to directory /usr/src/linux
+
+configure gadget as module:
+ "make menuconfig"
+ under "Code maturity level options" choose "Prompt for development ..."
+ goto "Device Drivers"
+ goto "USB support" -> "USB Gadget support"
+ choose "Support for USB Gadgets" as module
+ under choice "USB Peripheral Controller" choose "AMD5536-UDC"
+ under "USB Gadget Drivers"
+ choose "Gadget Zero" as module or
+ choose "Ethernet Gagdet" as module or
+ choose "File-backed Storage Gadget" as module
+ exit and save config
+
+compile and install modules:
+ "make modules modules_install"
+
+-------------------------------------------------------------------------------
+HOW TO USE IT:
+-------------------------------------------------------------------------------
+
+*** How to load FILE-BACKED STORAGE gadget driver - mass storage ***
+enable USB mass storage support for linux host:
+ change to directory /usr/src/linux
+ "make menuconfig"
+ under "File systems" choose "DOS/FAT/NT filesystems"
+ choose "MSDOS fs support"
+ under "Device Drivers" under "SCSI device support"
+ choose "SCSI device support"
+ choose "SCSI generic support"
+ under "Device Drivers" under "USB support" in section
+ "USB Device Class drivers" choose
+ "USB Mass Storage support"
+ compile new kernel
+create disk file:
+ "dd bs=1M count=128 if=/dev/zero of=/tmp/disk"
+ => creates a 128Mbyte image file /tmp/disk
+load modules:
+ "modprobe amd5536udc"
+ "modprobe g_file_storage file=/tmp/disk"
+ Note: multiple file arguments are possible, each will be a separate
+ drive for the host side, furthermore devices such as /dev/hda
+ (whole disk will be used) or /dev/hda1 (partition) can be used
+ as argument too
+ "modprobe amd5536uoc"
+create a primary FAT16 disk partition via linux host site:
+ "fdisk /dev/sda", make FAT16 prim. partition
+ => "n", "p", "1", "", "", "t", "6", "w",
+ "mkdosfs /dev/sda1"
+ "sync"
+create primary disk partition via Windows XP host site:
+ right click on "My Computer"
+ choose "Manage" => "Disk Management"
+ choose usb disk and follow instructions of partition menu
+mount usb mass storage device on linux host:
+ make directory "/mnt/gadget/"
+ "mount -t msdos /dev/sda1 /mnt/gadget"
+
+*** How to access files of disk image on UDC side ***
+When files were copied from host to UDC mass storage device then files
+are inside the monolitic disk image (see above) on UDC side. This
+disk image can be mounted via the loopback device driver to a
+directory on UDC side to access these files.
+Steps on UDC side:
+ enable kernel support for loopback device
+ change to directory /usr/src/linux
+ "make menuconfig"
+ under "Block devices" choose "Loopback device support"
+ and recompile the kernel
+ determine offset inside disk image:
+ "fdisk -l -u disk_image", output is like:
+>> You must set cylinders.
+>> You can do this from the extra functions menu.
+>>
+>> Disk /tmp/disk128: 5 heads, 52 sectors, 0 cylinders
+>> Units = sectors of 1 * 512 bytes
+>>
+>> Device Boot Start End Blocks Id System
+>> /tmp/disk128p1 52 262079 131014 6 FAT16
+
+ get offset my multiplying start value by sector size:
+ 52 * 512 = 26624
+ mount disk image:
+ "mount -o loop,offset=26624 -t msdos disk_image /mnt"
+
+
+*** How to load ZERO gadget driver - simple BULK loop back ***
+load modules:
+UDC driver:
+ (a) Slave/Fifo mode: "modprobe amd5536udc use_dma=0"
+ (b) DMA Buffer Fill mode: "modprobe amd5536udc use_dma=1"
+ default:
+ (c) DMA PPBNDU mode: "modprobe amd5536udc"
+ (d) DMA PPBDU mode: "modprobe amd5536udc use_dma=1 use_dma_ppb=1 use_dma_ppb_du=1"
+ (e) fullspeed mode: "modprobe amd5536udc use_fullspeed=1", can be combined
+ with all dma modes
+ (f) special higspeed
+ tx buffer size: "modprobe amd5536udc hs_tx_buf="
+ example: "modprobe amd5536udc use_dma=1 hs_tx_buf=128"
+ => buffer size = 512 bytes (=bulk max packet)
+Gadget Zero driver:
+ (a) Bulk loop: "modprobe g_zero"
+ (b) Int loop: "modprobe g_zero use_interrupt_traffic=1"
+ (c) Source/Sink "modprobe g_zero loopdefault=0"
+ OUT data must all be zero's
+ (d) Source/Sink count "modprobe g_zero loopdefault=0 pattern=1"
+ each OUT packet must count modulo63 (0,1,..,62,0,1,..)
+UOC driver: "modprobe amd5536uoc"
+example:
+ "modprobe amd5536udc"
+ "modprobe g_zero"
+ "modprobe amd5536uoc"
+ => loads driver for DMA PPBNDU mode and Bulk loop
+
+
+*** How to use ETHERNET gadget driver (CDC protocol) ***
+ with Linux Host
+UDC side bringup:
+ load gadget modules
+ "modprobe amd5536udc"
+ "modprobe g_ether"
+ "modprobe amd5536uoc"
+ "ifconfig usb0 192.168.0.2"
+Host side bringup:
+ install support for CDC Ethernet:
+ change to directory /usr/src/linux
+ "make menuconfig"
+ under "Device Drivers" under "USB support" under
+ "USB Network adapters" choose
+ "Multi-purpose USB Networking Framework"
+ choose "CDC Ethernet support"
+ compile mew kernel
+ "modprobe CDCEther"
+ "ifconfig eth1 192.168.0.1"
+ note: assuming there is one network card assigned to eth0,
+ otherwise kernel messages of CDC Ethernet module show
+ which interface (ethX) is used
+Use network connection:
+ after bringup of host and UDC side it behaves like a normal
+ ethernet connection between host and UDC
+ test the connection:
+ host side: "ping -I eth1 192.168.0.2"
+ UDC side : "ping -I usb0 192.168.0.1"
+ note: the "-I" option assures that the USB cable is used, the
+ option can be omitted when the routing table is setup to avoid
+ using other network interfaces as eth0

+Howto for Linux device driver for the AMD5536 USB Options Controller (UOC)
+--------------------------------------------------------------------------
+
+Author: Karsten Boge
+
+(1)Introduction
+===============
+
+The AMD5536 UOC is part of x86 southbridge AMD5536.
+The USB port is shared between the USB Host Controller
+and the USB Device Controller as defined in BIOS setup.
+The on-chip UOC controller is used to switch the
+usb port between host, UDC and neutral.
+The amd5536uoc driver is needed to get the
+USB Device Controller operating.
+
+(2) Patches
+===========
+
+udc.patch:
+ This containes the UDC driver as together
+ with the UOC driver
+
+(3) Driver source code installation
+===================================
+
+- New files for UOC:
+ drivers/usb/gadget/amd5536uoc.h
+ drivers/usb/gadget/amd5536uoc.c
+
+(4) BIOS setup
+==================
+
+ PCI Configuration
+ UDC: Enabled
+ OTG: Enabled
+ Port 4 assignment: Device
+
+(4) Config options
+==================
+
+ Support for USB Gadgets
+ USB Periheral Controller (?choice?)
+ (X) AMD5536UDC
+
+ The role of the UOC port can be defined
+ within the BIOS setup exclusively.
+
+ Selecting the amd5536udc driver results in
+ building the amd5536uoc driver too.
+ If "Support for USB Gadgets" is configured to be statically
+ linked both modules will be linked into the kernel image
+ otherwise an additional module called amd5536uoc will be built
+
+
+(5) Compile and install
+=======================
+
+ If global USB support is configured to be used as
+ kernel module (usbcore.o) (recomended):
+
+ make modules SUBDIRS=drivers/usb/gadget
+ make modules_install
+
+ If it's linked into the kernel image an new kernel
+ image must be compiled and created before.
+
+(6) Usage
+=========
+
+ modprobe amd5536uoc
+
+ This will load the module and other modules which provide
+ interfaces used by the UOC driver (usbcore, amd5536udc).
+
+ The amd5536uoc driver is needed to power up the uoc logic
+ which controls the pullup resistors connected to either
+ the D+ or D- USB pins.
+ The function of this pullup resistors is to signal the host
+ that a device is connected, and at which speed the device
+ operates.
+
+ Make sure the USB port is assigned to device within the
+ BIOS setup otherwise the modules will not be loaded.
