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 stuff.
There was some discussion on the list about this patch, and I somehow expected to receive an updated / modified version for it. But then the discussion dried out, and nothing happened.
What's the current state of this? Is there still a patch to add?
Hi Wolfgang,
I'll provide a fresh patch rsn - I put it on hold, since you appeared to be overloaded at the time...
Hi Wolfgang,
the attached patch (against CVS of last night) adds two configuration options: CONFIG_SERIAL_TAG and CONFIG_REVISION_TAG These options enable the functions setup_serial_tag() and setup_revision_tag(), which should be defined in the board-specific code when needed.
This provides a hook to pass ATAG_SERIAL (board serial number) and ATAG_REVISION (board revision) to the (ARM) kernel. These values appear in /proc/cpuinfo of the target.
Furthermore, the patch removes some redundant #defines from lib_arm/armlinux.c: tag_size(), tag_next() and ATAG_INITRD2 are all defined (unconditionally) in asm-arm/setup.h
CHANGELOG: * add configuration options CONFIG_SERIAL_TAG and CONFIG_REVISION_TAG to pass ATAG_SERIAL and ATAG_REVISION, resp., to the ARM target
Cheers Anders
