Patch by Bryan O'Donoghue <bodonoghue@codehermit.ie>, 29 May 2006
|

|
||||
* Fix PCI to memory window size problems on PM82x boards
|
||||
We use the "automatic" mode that was used for the MPC8266ADS and
|
||||
MPC8272 boards. Eventually this should be used on all boards?]

for single ended drivers: 0x00005000
|
||||
|
||||
- USB Device:
|
||||
Define the below if you wish to use the USB console.
|
||||
Once firmware is rebuilt from a serial console issue the
|
||||
command "setenv stdin usbtty; setenv stdout usbtty" and
|
||||
attach your usb cable. The Unix command "dmesg" should print
|
||||
it has found a new device. The environment variable usbtty
|
||||
can be set to gserial or cdc_acm to enable your device to
|
||||
appear to a USB host as a Linux gserial device or a
|
||||
Common Device Class Abstract Control Model serial device.
|
||||
If you select usbtty = gserial you should be able to enumerate
|
||||
a Linux host by
|
||||
# modprobe usbserial vendor=0xVendorID product=0xProductID
|
||||
else if using cdc_acm, simply setting the environment
|
||||
variable usbtty to be cdc_acm should suffice. The following
|
||||
might be defined in YourBoardName.h
|
||||
|
||||
CONFIG_USB_DEVICE
|
||||
Define this to build a UDC device
|
||||
|
||||
CONFIG_USB_TTY
|
||||
Define this to have a tty type of device available to
|
||||
talk to the UDC device
|
||||
|
||||
CFG_CONSOLE_IS_IN_ENV
|
||||
Define this if you want stdin, stdout &/or stderr to
|
||||
be set to usbtty.
|
||||
|
||||
mpc8xx:
|
||||
CFG_USB_EXTC_CLK 0xBLAH

Derive USB clock from external clock "blah"
|

- CFG_USB_EXTC_CLK 0x02

Derive USB clock from brgclk
|
||||
- CFG_USB_BRG_CLK 0x04
|
||||
|
||||
If you have a USB-IF assigned VendorID then you may wish to
|
||||
define your own vendor specific values either in BoardName.h
|
||||
or directly in usbd_vendor_info.h. If you don't define
|
||||
CONFIG_USBD_MANUFACTURER, CONFIG_USBD_PRODUCT_NAME,
|
||||
CONFIG_USBD_VENDORID and CONFIG_USBD_PRODUCTID, then U-Boot
|
||||
should pretend to be a Linux device to it's target host.
|
||||
|
||||
CONFIG_USBD_MANUFACTURER
|
||||
Define this string as the name of your company for
|
||||
- CONFIG_USBD_MANUFACTURER "my company"
|
||||
|
||||
CONFIG_USBD_PRODUCT_NAME
|
||||
Define this string as the name of your product
|
||||
- CONFIG_USBD_PRODUCT_NAME "acme usb device"
|
||||
|
||||
CONFIG_USBD_VENDORID
|
||||
Define this as your assigned Vendor ID from the USB
|
||||
Implementors Forum. This *must* be a genuine Vendor ID
|
||||
to avoid polluting the USB namespace.
|
||||
- CONFIG_USBD_VENDORID 0xFFFF
|
||||
|
||||
CONFIG_USBD_PRODUCTID
|
||||
Define this as the unique Product ID
|
||||
for your device
|
||||
- CONFIG_USBD_PRODUCTID 0xFFFF
|
