/*
* init_ide_data() sets reasonable default values into all fields
* of all instances of the hwifs and drives, but only on the first call.
* Subsequent calls have no effect (they don't wipe out anything).
*
* This routine is normally called at driver initialization time,
* but may also be called MUCH earlier during kernel "command-line"
* parameter processing. As such, we cannot depend on any other parts
* of the kernel (such as memory allocation) to be functioning yet.
*
* This is too bad, as otherwise we could dynamically allocate the
* ide_drive_t structs as needed, rather than always consuming memory
* for the max possible number (MAX_HWIFS * MAX_DRIVES) of them.
*
* FIXME: We should stuff the setup data into __init and copy the
* relevant hwifs/allocate them properly during boot.
