2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

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__.

2013-03-22x86: 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.

2012-07-05PCI Type2 config must dieRonald G. Minnich
PCI Type 2 config was a strange and never-used config mechanism. It is unlikely that in the 13 years of coreboot's existence that type 2 was ever used; it just made life complicated for everyone. It lived long enough in coreboot to be replaced by mmioconf. Prior to making the device tree visible in romstage we want to get rid of type2. Delete two files we don't need any more (yay!). Replace two functions with one: pci_config_default, which returns a pointer to the default config method. At some future time this may change to mmio but for now it is old type1 style.

2009-09-22If no pci access method has been set for the device tree so far (e.g.Carl-Daniel Hailfinger
during early coreboot_ram), pci_{read,write}_config{8,16,32} will die(). This patch changes pci_{read,write}_config{8,16,32} to use the existing PCI access method autodetection infrastructure instead of die()ing. Until r4340, any usage of pci_{read,write}_config{8,16,32} in coreboot_ram before the device tree was set up resulted in either a silent hang or a NULL pointer dereference. I changed the code in r4340 to die() properly with a loud error message. That still was not perfect, but at least it allowed people to see why their new ports died. Still, die() is not something developers like to see, and thus a patch to automatically pick a sensible default instead of dying was created. Of course, handling PCI access method selection automatically for fallback purposes has certain limitations before the device tree is set up. We only check if conf1 works and use conf2 as fallback. No further tests are done. This patch enables cleanups and readability improvements in early coreboot_ram code: Without this patch: dword = pci_cf8_conf1.read32(&pbus, sm_dev->bus->secondary, sm_dev->path.pci.devfn, 0x64); With this patch: dword = pci_read_config32(sm_dev, 0x64); Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4646 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
