drop a lot of dead code, including an old winbond southbridge from our removed
ppc port, some ambiguous use of CONFIG_IDE and an unused ide driver (we dropped the filesystems already to be used with it) (somewhat trivial) Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4828 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

* long, so we must be very careful here.
|

*
|

*
|

* - The BSY bit not being set while the IDE drives spin up.
|

* In this cases only a hard coded delay will work. As

* IDE drives the work around can be enabled by setting
|
||||
* BSY_SET_DURING_SPINUP to 0.
|
||||
*
|
||||
* - The BSY bit floats high when no drives are plugged in.
|
||||
* This case will not be detected except by timing out but
|
||||
* we avoid the problems by only probing devices we are
|
||||
* supposed to boot from. If we don't do the probe we
|

* will not experience the problem.
