[U-Boot-Users] Support for the ML507 Xilinx Board
by Ricardo Ribalda Delgado 11 Jul '08

11 Jul '08

Hi List: <Sorry for the multiple submitions, but I think that this will safe a lot of time for our main developers. BTW: This is the first time I use git> This is my first contribution to u-boot. I have ported u-boot to the ML507 Board by Xilinx. http://www.xilinx.com/products/devkits/HW-V5-ML507-UNI-G.htm This boards includes an FPGA Virtex 5 FX with an embedded PowerPC 440. The port supports: -Virtex 5 ppc440x5 -XIlinx Interrupt Controller -Xilinx I2C Controller (Interrupted mode) -Xilinx Uart Lite (simple port) -Xilinx LL_TEMA (Interrupted and SGDMA) -Save environment on board eeprom -DTT support for the ADT sensor on board (new hwmon driver) -Dummy I2C driver (for testing purposes) This patch works against the last commit to the p4xx branch. I am a researcher of the Universidad Autonoma de Madrid, and this work has been supported by Q-Technology ( http://qtec.com ) under a Research Agreement. Any comment will be very welcomed.

[U-Boot-Users] Support for the ML507
by Ricardo Ribalda Delgado 11 Jul '08

11 Jul '08

Hello again: This is my third submission of the same thing, please be indulgent....: This month I have been working on the ml507 board, trying to give it support. This boards has a lot of components and I have developed drivers for some of them. On my first submission, the board and the drivers were on a single diff file. The mail list didn't like a message so big so I cutted it in 4 parts, bziped it and resend it. Later on I have realized that, it do not support the guidelines on the web.... And it will be huge work for the mantainers to check all that code So, I have spent the evening dividing the big patch in 8 independent patches. I have used the git tools to prepare the patches and resend them... Unfortunatelly some of this files are bigged than the 40kb limit.... If the mail list administrator don't accept this parts you can download the full set of patches from my website: http://www.ii.uam.es/~rribalda/ml507.tgz Why my patches are so big... They give support to IPs by Xilinx, which have some kind of generic drivers to adapt them to multiple OS... When the driver was very complex I have used this generic drivers and added an adaptor. Because it does not follows the coding guidelines, all this drivers have been located under the board directory to respect all your "clean" work. Sorry for the mess I have created in just a matter of minutes. Best Regards and I hope to see my code on the main line someday. -- Ricardo Ribalda http://www.eps.uam.es/~rribalda/
