Linux 2.4.19-rmk7-pxa2-adsx6

This version

Only supports AGX and BitsyX boards.

Adds support for USB on AGX. (Devices that require isochronous transfers (e.g. webcams) are not supported. Control, bulk, and interrupt transfers are supported so other device types (e.g. mice, keyboards, storage devices) work as long as there is a linux device driver available for it.)

Adds support for RevC BitsyX and for the new UART connector board for the BitsyX

Supports new CPLD firmware on AGX with edge IRQs

Enables DMA on Ethernet

Enables variable sample rates on AC97 codec

Sets noctty to 1 in tty_io.c to avoid a reported problem with ‘agetty’. This change prohibits job control when logged into /dev/console so the ramdisk was modified to use /dev/ttyS? instead of /dev/console.)

Important Warnings and Requirements

Do not use a connector board older than Rev A on the BitsyX.

To build the kernel, you must use a compiler that supports the Xscale CPU.
You can use the one we used to build the precompiled kernels provided below.
Download arm-2.95.3.tar.gz , untar it in /usr/local/ and add it to your path.
```
cd /usr/local
tar xzf arm-2.95.3.tar.gz
PATH=/usr/local/pxa/bin:$PATH
```

There is an update for the BitsyX that turns off USB power during sleep. To get this update, download and apply the following patch: diff-2.4.19-rmk7-pxa2-adsx6-usb1.

The precompiled kernel image for the BitsyX does not include this update.
