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

Hi,

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.

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?

CHANGELOG: add config option CONFIG_CUSTOM_TAGS
