Hmm, it was the first hit using a web search engine :) http://www.freescale.com/files/microcontrollers/doc/user_guide/MPC5200UM.pdf?WT_TYPE=Users%20Guides&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation > Is there a #define that I can use to distinguish between the two > processor variants? Querying the PVR register is not a nice solution I think you should have two different functions for calculation, one for 5200 and one for 5200B. During init query the device tree for 'fsl,mpc5200-psc-spi' or 'fsl,mpc5200b-psc-spi' and make the driver use the proper function. (BTW I haven't checked for further differences between 5200 and 5200B; there may be more) Regards, Wolfram -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
