      ath10k: sdio: add firmware coredump support · 3c45f21a
      Wen Gong authored
      When firmware crashes it's possible to create a coredump for later analysis,
      add support to collect the register and memory info from SDIO devices.
      
      The coredump configuration is different between QCA6174 PCI and QCA6174 SDIO,
      so add specific registers and memory regions for the latter.
      
      QCA6174 SDIO has two methods to dump the firmware: fastdump and slowdump.
      Fastdump is not supported in olded versions of firmware, and for these ath10k
      will automatically select slowdump. If firmware supports fastdump, ath10k will
      automatically select it. QCA6174 SDIO firmware version
      WLAN.RMH.4.4.1-00017-QCARMSWPZ-2 is the first version supporting fastdump.
      
      For slowdump, ath10k_sdio_hif_diag_read() can not be used as the diag
      window has a limit value, it is 4 bytes and the dump's buffer length is larger
      than it, it will trigger error. So this patch adds ath10k_sdio_read_mem() to
      read 4 bytes for each time.
      
      Example output of a firmware crash:

      ath10k: add bus type for each layout of coredump · c796d513
      Wen Gong authored
      For some hw version, it has more than one bus type, it need to add bus
      type to distinguish different chip.
