What do I pass to cbfs_run_payload() after finding the payload with romfile_find() ?

[Dave Frodin]

I'm having a problem finding/loading/executing a payload from seabios which is now using the romfile 
functions for cbfs (commit 59d6ca52a7eba5). 
I do have the cpu_to_be32() patch to get the correct payload destination address.

Here's what I had previously that worked before the change...

// Output the LCD splash image to the Explorer board 
struct cbfs_file *file; 
dprintf(1,"Looking for Explorer LCD splash payload ... "); 
file = cbfs_finddatafile("img/explorer-splash"); 
if(file) 
{ 
dprintf(1," found file [%s]. Loading it...\n ",file->filename); 
cbfs_run_payload(file); 
} 
else dprintf(1,"could NOT find it!\n");

This is where I'm at after the change ...

// Output the LCD splash image to the Explorer board 
struct romfile_s *file; 
dprintf(1,"Looking for Explorer LCD splash payload ... "); 
file = romfile_find("img/explorer-splash"); 
if(file) 
{ 
dprintf(1," found file [%s]. Loading it...\n ",file->name); <=== everything works up to here 
// cbfs_run_payload(); 
} 
else dprintf(1,"could NOT find it!\n");

The cbfs_run_payload is expecting (cbfs_file *). How do I extract what cbfs_run_payload() wants from what 
I got back from romfile_find() ?

Thanks in advance, 
Dave

cbfs_run_payload((void*)file->id);

Kevin,
Well that was easy enough.

Thanks, again
