Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

1 | ADS GraphicsMaster Single Board Computer | ||
2 | |||
3 | For more details, contact Applied Data Systems or see | ||
4 | http://www.applieddata.net/products.html | ||
5 | |||
6 | The original Linux support for this product has been provided by | ||
7 | Nicolas Pitre <nico@cam.org>. Continued development work by | ||
8 | Woojung Huh <whuh@applieddata.net> | ||
9 | |||
10 | Use 'make graphicsmaster_config' before any 'make config'. | ||
11 | This will set up defaults for GraphicsMaster support. | ||
12 | |||
13 | The kernel zImage is linked to be loaded and executed at 0xc0400000. | ||
14 | |||
15 | Linux can be used with the ADS BootLoader that ships with the | ||
16 | newer rev boards. See their documentation on how to load Linux. | ||
17 | |||
18 | Supported peripherals: | ||
19 | - SA1100 LCD frame buffer (8/16bpp...sort of) | ||
20 | - SA1111 USB Master | ||
21 | - on-board SMC 92C96 ethernet NIC | ||
22 | - SA1100 serial port | ||
23 | - flash memory access (MTD/JFFS) | ||
24 | - pcmcia, compact flash | ||
25 | - touchscreen(ucb1200) | ||
26 | - ps/2 keyboard | ||
27 | - console on LCD screen | ||
28 | - serial ports (ttyS[0-2]) | ||
29 | - ttyS0 is default for serial console | ||
30 | - Smart I/O (ADC, keypad, digital inputs, etc) | ||
31 | See http://www.applieddata.com/developers/linux for IOCTL documentation | ||
32 | and example user space code. ps/2 keybd is multiplexed through this driver | ||
33 | |||
34 | To do: | ||
35 | - everything else! :-) | ||
36 | |||
37 | Notes: | ||
38 | |||
39 | - The flash on board is divided into 3 partitions. mtd0 is where | ||
40 | the zImage is stored. It's been marked as read-only to keep you | ||
41 | from blasting over the bootloader. :) mtd1 is | ||
42 | for the ramdisk.gz image. mtd2 is user flash space and can be | ||
43 | utilized for either JFFS or if you're feeling crazy, running ext2 | ||
44 | on top of it. If you're not using the ADS bootloader, you're | ||
45 | welcome to blast over the mtd1 partition also. | ||
46 | |||
47 | - 16bpp mode requires a different cable than what ships with the board. | ||
48 | Contact ADS or look through the manual to wire your own. Currently, | ||
49 | if you compile with 16bit mode support and switch into a lower bpp | ||
50 | mode, the timing is off so the image is corrupted. This will be | ||
51 | fixed soon. | ||
52 | |||
53 | Any contribution can be sent to nico@cam.org and will be greatly welcome! | ||
