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.

2019-12-02src/: Remove g_ prefixes and _g suffixes from variablesPatrick Georgi
These were often used to distinguish CAR_GLOBAL variables that weren't directly usable. Since we're getting rid of this special case, also get rid of the marker. This change was created using coccinelle and the following script: @match@ type T; identifier old =~ "^(g_.*|.*_g)$"; @@ old @script:python global_marker@ old << match.old; new; @@ new = old if old[0:2] == "g_": new = new[2:] if new[-2:] == "_g": new = new[:-2] coccinelle.new = new @@ identifier match.old, global_marker.new; @@ - old + new @@ type T; identifier match.old, global_marker.new; @@ - T old; + T new; @@ type T; identifier match.old, global_marker.new; @@ - T old + T new = ...; There were some manual fixups: Some code still uses the global/local variable naming scheme, so keep g_* there, and some variable names weren't completely rewritten.

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.

Update lib_vpd.c (only containing vpd_decode.c) to latest version from https://chromium.googlesource.com/chromiumos/platform/vpd The called module (vpd.c) has been also corrected for new lib_vpd types and constants. BUG=chromium:967209 TEST=select VPD config on kukui; make; boots on at least kukui boards.

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.
