Re: Which microcode patch for MPC870?
Which microcode patch should be selected for MPC870? In the old 2.4 kernel, the CONFIG_UCODE_PATCH was selected. What's the corresponding config: CONFIG_USB_SOF_UCODE_PATCH or CONFIG_I2C_SPI_UCODE_PATCH or CONFIG_I2C_SPI_SMC1_UCODE_PATCH? Since my board doesn't have USB, I believe USB microcode is irrelevant here. So it comes down the other two choices. Of course do I really need the patch? My board has I2C and SMC1, but no SPI. I chose CONFIG_I2C_SPI_UCODE_PATCH as an experiment but got the following compilation error: These errors were fixed by http://patchwork.ozlabs.org/patch/58262/ and http://patchwork.ozlabs.org/patch/58263/ Thanks a lot for the info, Anton. Then the question is which patch should be selected. I don't enable any patch and the SMC UART works properly. Next I'm going to enable I2C but I don't know whether a microcode patch is required or not. Thanks, -Shawn. ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
