2019-09-30device/pci_early: Drop some __SIMPLE_DEVICE__ useKyösti Mälkki
The simple PCI config accessors are always available under names pci_s_[read|write]_configX. We have some use for PCI bridge configurations and resets in romstages, so expose them.

2019-09-17AUTHORS: Move src/device copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time.

2019-02-11device/pci_ops: Apply some symmetry in headersKyösti Mälkki
To make PCI driver side arch-agnostic, function declarations have to be in symmetrical header file locations. From the driver side, the correct file to include is now <device/pci_ops.h> Change-Id: I8076a4867fd7472beaae0a021dcf0d9c7c905871 Signed-off-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-on: https://review.coreboot.org/c/31306 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
2019-02-11device/pci_ops: Move questionable pci_locate() variantsKyösti Mälkki
These are defined for __SIMPLE_DEVICE__ when PCI enumeration has not happened yet. These should not really try to probe devices other than those on bus 0. It's hard to track but there maybe cases of southbridge being located on bus 2 and available for configuration, so I rather leave the code unchanged. Just move these out of arch/io.h because they cause build failures if one attempts to include <arch/pci_ops.h> before <arch/io.h>. There are two direct copies for ROMCC bootblocks to avoid inlining them elsewhere.

2018-12-30device/pci_early: Fixes for __SIMPLE_DEVICE__Kyösti Mälkki
The feature is used to enable PCI MMIO accesses behind PCIe links (or bridges) before PCI enumeration has been completed. Add the feature for bootblock, verstage and postcar, it is required with add-on PCIe serial cards for early console output. It's up to the board specific code to configure PCIe root port prior to calling console_init() for this to work. Remove feature from ramstage, it bypasses any resource allocations and bus number assignments. For the moment PCI configuration support before ramstage is available only on ARCH_X86. Also switch from device_t to pci_devfn_t.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
2014-07-19device/pci_early.c: Mixes up variants of a typedefs to 'u32'Edward O'Callaghan
Unfortunately coreboot has to deal with ROMCC's short comings which has lead to a little bit of confusion due to typedefs. Essentially, coreboot defines four typedefs: * 'typedef struct device * device_t' in ramstage not in SIMPLE_DEVICE mode * 'typedef u32 device_t' in romstage or when SIMPLE_DEVICE is defined * 'typedef u32 pnp_devfn_t' * 'typedef u32 pci_devfn_t' Some early functions make use of 'device_t' over 'pci_devfn_t' and since the C type-checker does not enforce typedefs to the same type 'u32' these are never noticed. Fix these so that 'device_t' does not conflict in romstage for later work. We later plan to have 'pnp_devfn_t' and 'pci_devfn_t' as the only variants of 'u32' and 'device_t' to be a struct pointer type exclusively.
