It is just DRA74x_EVM and AM57XX evm is using different instances of XHCI. Ideally this base address should be coming from DT. I don't think it is a good idea to introduce CONFIG_AM57XX.

I agree that the resolution should be higher. The exact SOC id (CONFIG_AM572X, CONFIG_DRA74X, CONFIG_DRA75X...) should be determined by the target selection - board file or Kconfig. The ifdef'ery should include the exact SOCs id. According to the provided TRMs, CONFIG_AM572X and CONFIG_DRA74X will be located in the same ifdef'ery case. -- Regards, Uri ^ permalink raw reply [flat|nested] 8+ messages in thread
