A large number of the following errors is reported when compiling
with clang:
cvmx-bootinfo.h:326:3: error: adding 'int' to a string does not append to the string [-Werror,-Wstring-plus-int]
ENUM_BRD_TYPE_CASE(CVMX_BOARD_TYPE_NULL)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cvmx-bootinfo.h:321:20: note: expanded from macro 'ENUM_BRD_TYPE_CASE'
case x: return(#x + 16); /* Skip CVMX_BOARD_TYPE_ */
~~~^~~~
cvmx-bootinfo.h:326:3: note: use array indexing to silence this warning
cvmx-bootinfo.h:321:20: note: expanded from macro 'ENUM_BRD_TYPE_CASE'
case x: return(#x + 16); /* Skip CVMX_BOARD_TYPE_ */
^
Follow the prompts to use the address operator '&' to fix this error.
