  	bool "Enable CN63XXP1 errata worarounds"
  	default "n"
  	help
  	  The CN63XXP1 chip requires build time workarounds to
  	  function reliably, select this option to enable them.  These
  	  workarounds will cause a slight decrease in performance on
  	  non-CN63XXP1 hardware, so it is recommended to select "n"
  	  unless it is known the workarounds are needed.

  	bool "Build the kernel to be used as a 2nd kernel on the same chip"
  	default "n"
  	help
  	  This option configures this kernel to be linked at a different
  	  address and use the 2nd uart for output. This allows a kernel built
  	  with this option to be run at the same time as one built without this
  	  option.

  	help
  	  CVMSEG LM is a segment that accesses portions of the dcache as a
  	  local memory; the larger CVMSEG is, the smaller the cache is.
  	  This selects the size of CVMSEG LM, which is in cache blocks. The
  	  legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is
  	  between zero and 6192 bytes).

  	bool "Lock the exception handler in L2"
