[U-Boot-Users] [PATCH] pass custom data to Linux

the attached patch defines a new config option CONFIG_CUSTOM_TAGS for
ARM targets.

Defining this option causes do_bootm_linux() to call the function
setup_custom_tags(), which should be supplied from the board-specific

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).

   add config option CONFIG_CUSTOM_TAGS
