2013-06-17pnp: Implement common handling for PnP config modesNico Huber
Many super i/o chips only answer to PnP requests if they are in a configuration state (sometimes also called ext func mode). To cope with that, the code of many chips implements its own version of our default PnP functions like pnp_set_resource(), pnp_enable_resource() etc. To avoid this code duplication, this patch extends our PnP device interface with optional functions to enter and exit configuration mode.

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.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2010-12-05W83627DHG/W83627EHG fixups for virtual LDNs.Uwe Hermann
W83627DHG: - Add proper "virtual LDN" handling for the LDNs that need it (i.e., those that don't have their "enable" bit in bit 0 of the 0x30 register). - Fix various I/O masks in the pnp_dev_info[] array as per datasheet. Add missing PNP_IRQ0 to the W83627DHG_ACPI LDN. W83627EHG: - Similar to W83627DHG, improve the "virtual LDN" setup a bit (it was mostly implemented already, though). - Add missing PNP_IRQ0 to the W83627EHG_ACPI LDN. Also: Fix up devicetree.cb of all boards using W83627DHG/W83627EHG to adapt for the virtual LDNs. include/device/pnp.h: Add comment that 'function' (which refers to the LDN and should probably be renamed later) has to be at least 16 bits wide. In theory LDNs could use u8, but due to the virtual LDN info being encoded in the "high byte" of 'function' it must be at least u16. asrock/939a785gmh/romstage.c: Drop unused GPIO6_DEV. ibase/mb899/romstage.c: Use DUMMY_DEV instead of a specific LDN (serial port 1 in this case) to avoid confusion. The global registers manipulated there are accessible from any LDN.

2009-03-13This, ladies and gentlement, is commit #4000.Stefan Reinauer
Use the (almost) same strict CFLAGS in v2 that we use on v3. And fix a few include files and missing prototypes. Also, fix up the Config-abuild.lb files to properly work for cross compiling.

2004-03-11- Moved hlt() to it's own header.Eric Biederman
- Reworked pnp superio device support. Now complete superio support is less than 100 lines. - Added support for hard coding resource assignments in Config.lb - Minor bug fixes to romcc - Initial support for catching the x86 processor BIST error codes. I've only seen this trigger once in production during a very suspcious reset but... - added raminit_test to test the code paths in raminit.c for the Opteron - Removed the IORESOURCE_SET bit and added IORESOURCE_ASSIGNED and IORESOURCE_STORED so we can tell what we have really done. - Added generic AGP/IOMMU setting code to x86 - Added an implementation of memmove and removed reserved identifiers from memcpy - Added minimal support for booting on pre b3 stepping K8 cores - Moved the checksum on amd8111 boards because our default location was on top of extended RTC registers - On the Hdama added support for enabling i2c hub so we can get at the temperature sensors. Not that i2c bus was implemented well enough to make that useful. - Redid the Opteron port so we should only need one reset and most of memory initialization is done in cpu_fixup. This is much, much faster. - Attempted to make the VGA IO region assigment work. The code seems to work now... - Redid the error handling in amdk8/raminit.c to distinguish between a bad value and a smbus error, and moved memory clearing out to cpufixup. - Removed CONFIG_KEYBOARD as it was useless. See pc87360/superio.c for how to setup a legacy keyboard properly. - Reworked the register values for standard hardware, moving the defintions from chip.h into the headers of the initialization routines. This is much saner and is actually implemented. - Made the hdama port an under clockers BIOS. I debuged so many interesting problems. - On amd8111_lpc added setup of architectural/legacy hardware - Enabled PCI error reporting as much as possible. - Enhanded build_opt_tbl to generate a header of the cmos option locations so that romcc compiled code can query the cmos options. - In romcc gracefully handle function names that degenerate into function pointers - Bumped the version to 1.1.6 as we are getting closer to 2.0 TODO finish optimizing the HT links of non dual boards TODO make all Opteron board work again TODO convert all superio devices to use the new helpers TODO convert the via/epia to freebios2 conventions TODO cpu fixup/setup by cpu type git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1390 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
