2014-05-13src/drivers/pc80: Remove empty struct keyboardEdward O'Callaghan
This is a empty struct that has propagated through the superio's & ec's but really does nothing. Time to get rid of it before it adds yet more cruft. However, since this touches many superio's at once we do this in stages by first changing the function type to be a pure procedure.

2013-06-17pnp: Register implementations of enter/exit config stateNico Huber
Find all the (ramstage) implementations of enter()/exit() functions for the configuration state, register and call them through the new struct pnp_mode_ops. As our standard PnP functions are aware of the pnp_mode_ops, it's not necessary to call enter()/exit() around them anymore. Patch generated with the cocci below. It's not perfect. The movement of the enter()/exit() calls is somehow fragile. So I checked the remaining calls for sense, and changed some empty lines. Also a duplicate insertion of pnp_conf_mode_ops had to be removed. /* Try to find enter and exit functions by their outb() structure and their usage around calls to our standard pnp functions: */ @ enter_match @ identifier enter; identifier dev; type device_t; @@ void enter(device_t dev) { <... outb(..., dev->path.pnp.port); ...> } @ exit_match @ identifier exit; identifier dev; type device_t; @@ void exit(device_t dev) { <... outb(..., dev->path.pnp.port); ...> } @ pnp_match @ identifier op; identifier pnp_op =~ "^pnp_((alt_|)enable|(set|enable)_resources)$"; identifier enter_match.enter, exit_match.exit; type device_t; identifier dev; @@ void op(device_t dev) { ... enter(dev); ... pnp_op(dev); ... exit(dev); ... } /* Now add enter/exit to a pnp_mode_ops structure: */ @ depends on pnp_match @ identifier enter_match.enter; identifier exit_match.exit; identifier ops; @@ +static const struct pnp_mode_ops pnp_conf_mode_ops = { + .enter_conf_mode = enter, + .exit_conf_mode = exit, +}; + struct device_operations ops = { ..., + .ops_pnp_mode = &pnp_conf_mode_ops, }; /* Match against the new structure as we change the code and the above matches might not work anymore: */ @ mode_match @ identifier enter, exit, ops; @@ struct pnp_mode_ops ops = { .enter_conf_mode = enter, .exit_conf_mode = exit, }; /* Replace enter()/enter() calls with new standard calls (e.g. pnp_enter_conf_mode()): */ @@ identifier mode_match.enter; expression e; @@ -enter(e) +pnp_enter_conf_mode(e) @@ identifier mode_match.exit; expression e; @@ -exit(e) +pnp_exit_conf_mode(e) /* If there are calls to standard PnP functions, (re)move the enter()/exit() calls around them: */ @@ identifier pnp_op =~ "^pnp_((alt_|)enable|(set|enable)_resources)$"; expression e; @@ -pnp_enter_conf_mode(e); pnp_op(e); +pnp_enter_conf_mode(e); ... pnp_exit_conf_mode(e); @@ identifier pnp_op =~ "^pnp_((alt_|)enable|(set|enable)_resources)$"; expression e; @@ pnp_enter_conf_mode(e); ... +pnp_exit_conf_mode(e); pnp_op(e); -pnp_exit_conf_mode(e); @@ expression e; @@ -pnp_enter_conf_mode(e); -pnp_exit_conf_mode(e); Change-Id: I5c04b0c6a8f01a30bc25fe195797c02e75b6c276 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: http://review.coreboot.org/3482 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2013-06-17pnp: Provide alternative pnp_enable() implementationNico Huber
The current default implementation of pnp_enable() only disables devices - if set so in the devicetree - but does not enable them. Enablement takes place in pnp_enable_resources(). Yet, many PnP chips implement their own version of pnp_enable() which also enables devices if set in the devicetree. It's arguable, if enabling those devices makes sense, before they get resources assigned. Maybe we can't write the resource registers if not, who knows? The least we can do is providing a common implementation for this behavior, and get rid of some code duplication. Used the following cocci: @@ expression e; @@ +pnp_alt_enable(e); -pnp_set_logical_device(e); ( -pnp_set_enable(e, !!e->enabled); | -(e->enabled) ? pnp_set_enable(e, 1) : pnp_set_enable(e, 0); | -if (e->enabled) { pnp_set_enable(e, 1); } -else { pnp_set_enable(e, 0); } ) Change-Id: I8d695e8fcd3cf8b847b1aa99326b51a554700bc4 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: http://review.coreboot.org/3480 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.

2012-11-28Remove assembly coded log2 functionRonald G. Minnich
As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.
