-1 shouldn't be assigned to an unsigned variable, so use an otherwise unused constant here. Since 7 is the highest virtual LDN number, using 0xffff as PNP_SKIP_FUNCTION marker has no unwanted side effects.

2015-12-29device/pnp: Ability to set vendor specific logical device configDamien Zammit
According to the PNP ISA v1.0a spec, config registers in the range of 0xf0 up to 0xfe are vendor defined and may be used for any purpose. Config register 0xff is reserved and is defined as such. Currently, only vendor specific registers 0xf0, 0xf1, 0xf4, and 0xfa are able to be set using the PNP_MSCx bit flag masks. This patch adds support for all 15 vendor specific config registers, and updates the existing superio pnp_info to use them where appropriate.

2013-08-01Add directive __SIMPLE_DEVICE__Kyösti Mälkki
The tests for __PRE_RAM__ or __SMM__ were repeatedly used for detection if dev->ops in the devicetree are not available and simple device model functions need be used. If a source file build for ramstage had __PRE_RAM__ inserted at the beginning, the struct device would no longer match the allocation the object had taken. This problem is fixed by replacing such cases with explicit __SIMPLE_DEVICE__.

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.

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
