2020-06-02drivers/vpd: add VPD region VPD_RW_THEN_ROJonathan Zhang
This change is based on the concept that system user's (overwrite) settings are held in VPD_RW region, while system owner's (default) settings are held in VPD_RO region. Add VPD_RW_THEN_RO region type, so that VPD_RW region is searched first to get overwrite setting, otherwise VPD_RO region is searched to get default setting.

2020-06-02drivers/vpd: rename VPD_ANY to VPD_RO_THEN_RWJonathan Zhang
Rename VPD_ANY to VPD_RO_THEN_RW, to reflect the VPD region search preference. Update all existing code references for VPD_ANY.

2020-05-28drivers/vpd: Fix VPD speed regressions on non-x86 devicesJulius Werner
CB:34634 expanded the VPD code to also be usable from romstage, shuffling a few things around and adding some extra infrastructure in the process. Unfortunately, the changes seem to have only been written with x86 devices in mind and make coreboot always load the whole VPD FMAP section (not just the used part) on devices where rdev_mmap() is not a no-op. This patch rewrites the VPD code to be based on region_device structures that only represent the VPD area actually used (rather than the whole FMAP section), and that only get mapped when accessed. (It would be even better to pull this concept into the VPD decoder itself, but since that is taken from third-party code and accesses in early stages aren't very common, let's not go there for now.) It also moves the copying into CBMEM to romstage so that late romstage accesses can already benefit from it, and makes early decoding available in all stages because at this point, why not. Also fix a long-standing bug where the 'consumed' counter was not reset between vpd_decode_string() calls to the RO and the RW VPD.

2020-05-25drivers: Use SPDX identifiersJacob Garber
Convert the remaining files in src/drivers to use SPDX identifiers. int15.h and default_brightness_levels.asl did not have license headers, but they were both copied from other GPL2 files, so they should be under the GPL2 as well. ne2k.c and drm_dp_helper.h are licensed under custom BSD-like licenses that do not have an SPDX equivalent, so they are added as exceptions to the license header lint.

2019-11-18include: Make stdbool.h a separate fileJulius Werner
This patch moves the traditional POSIX stdbool.h definitions out from stdint.h into their own file. This helps for using these definitions in commonlib code which may be compiled in different environments. For coreboot everything should chain-include this stuff via types.h anyway so nothing should change.

2019-09-02drivers/vpd: add framework to search VPD in romstageJonathan Zhang
Summary: Added a framework to search VPD in romstage before memory is avilable. vpd_cbmem.c and vpd_premem.c are added for code specific for premem environment and for environment that cbmem can be used. Since global variable is forbidden in romstage. A CAR_GLOBAL variable is defined in vpd.c. This variable holds VPD binary blobs' base address and size from memory mapped flash. The overall flow is: * The CAR variable g_vpd_blob is initialized if it was not, either at romstage (before FSP-M execution in case of FSP UPD customization), or at ramstage. * At ramstage, during CBMEM_INIT, the VPD binary blob contents are copied into CBMEM. * At vpd_find() which may be called at romstage or at ramstage, it sets storage for a local struct vpd_blob variable. * The variable gets contents duplicated from g_vpd_blob, if vpd_find() is called at romstage. * The variable gets contents obtained from CBMEM, if vpd_find() is called at ramstage. Added a call vpd_get_bool(). Given a key/value pair in VPD binary blob, and name of a bool type variable, set the variable value if there is a match. Several checks are in place: * The key/value length needs to be correct. * The key name needs to match. * THe value is either '1' or '0'. Test Plan: * Build an OCP MonoLake coreboot image, flash and run.

2018-09-09drivers/vpd: Add VPD supportPatrick Rudolph
VPD reference: https://chromium.googlesource.com/chromiumos/platform/vpd/+/master/README.md Copy ChromeOS VPD driver to add support for VPD without CROMEOS. Possible use case: * Storing calibration data * Storing MAC address * Storing serial * Storing boot options + Now it's possible to define the VPD space by choosing one of the following enums: VPD_ANY, VPD_RW, VPD_RO. + CHROMEOS selects now VPD as part of it. + VPD is implemented as driver.
