[U-Boot-Users] CONFIG_SERIAL_TAG and CONFIG_REVISION_TAG ???

Hi there,

for ARM boards CONFIG_SERIAL_TAG and CONFIG_REVISION_TAG can be used to pass the board's serial nummber and revision to a linux kernel.

For now setup_serial_tag() has to be defined in board specific files. But setup_revision_tag() is defined in armlinux.c like

void setup_revision_tag(struct tag **in_params) { u32 rev = 0; #ifdef CONFIG_OMAP2420H4 u32 get_board_rev(void);

rev = get_board_rev(); #endif params->hdr.tag = ATAG_REVISION; params->hdr.size = tag_size (tag_revision); params->u.revision.rev = rev; params = tag_next (params); }

I'd love to make this consistent. So either do it like setup_serial_tag() or like setup_serial_tag() ...

Since I don't like board specific defines like "#ifdef CONFIG_OMAP2420H4" in common files we should move that out.

So the question is:

shell we implement board specific get_board_rev() and get_board_serial() and have the params->hdr.* stuff in armlinux.c?

or

shell we implement setup_serial_tag() and setup_serial_tag() in board specific files and do the params->hdr.* stuff there?

Comments please.

Thanks,

Steven
