Specifically, I need to pass the board revision and serial number to the Linux kernel, and I'd like to use the standard method of passing tagged parameters. For my purpose, ATAG_SERIAL and ATAG_REVISION are already defined (and supported by the kernel).
Since you say you are using standard ARM Linux tags to do this, why not just add support for CONFIG_{REVISION,SERIAL}_TAG in lib_arm/armlinux.c?
Hi George,
the tags are standard, but by nature the information is board-specific, so I don't see how lib_arm/armlinux.c could do much more than simply calling a function from the board tree. Do you think my idea of adding the hook setup_custom_tags() is _too_ generic?
Perhaps we can use environment variables to initialise those common tags in armlinux.c. Those environment variable can then be uniquely initialised/defined in whatever way makes sense for a given target port?
