2021-05-28option: Allow mainboards to implement the APIAngel Pons
Some mainboards need a mainboard-specific mechanism to access option values. Allow mainboards to implement the option API. Also, add some documentation about the current option API, and describe when should one reimplement the option API in mainboard code: only when the code is mainboard-specific to comply with externally-imposed constraints.

2021-05-03util/sconfig: Add support for discontiguous FW_CONFIG fieldsTim Wawrzynczak
Sooner or later, some board was going to need extra FW_CONFIG bits for a field that was already in production, so this patch adds support for adding extra (unused) bits to a field. The extra are appended via a syntax like: `field FIELD_NAME START0 END0 | START1 END1 | START2 END2 ...` and the suffixed bits are all treated as if they are contiguous when defining option values. BUG=b:185190978 TEST=Modified volteer fw_config to the following: field AUDIO 8 10 | 29 29 | 31 31 option NONE 0 option MAX98357_ALC5682I_I2S 1 option MAX98373_ALC5682I_I2S 2 option MAX98373_ALC5682_SNDW 3 option MAX98373_ALC5682I_I2S_UP4 4 option MAX98360_ALC5682I_I2S 5 option RT1011_ALC5682I_I2S 6 option AUDIO_FOO 7 option AUDIO_BAR 8 option AUDIO_QUUX 9 option AUDIO_BLAH1 10 option AUDIO_BLAH2 15 option AUDIO_BLAH3 16 option AUDIO_BLAH4 31 end which yielded (in static_fw_config.h): FW_CONFIG_FIELD_AUDIO_MASK 0xa0000700 FW_CONFIG_FIELD_AUDIO_OPTION_NONE_VALUE 0x0 FW_CONFIG_FIELD_AUDIO_OPTION_MAX98357_ALC5682I_I2S_VALUE 0x100 FW_CONFIG_FIELD_AUDIO_OPTION_MAX98373_ALC5682I_I2S_VALUE 0x200 FW_CONFIG_FIELD_AUDIO_OPTION_MAX98373_ALC5682_SNDW_VALUE 0x300 FW_CONFIG_FIELD_AUDIO_OPTION_MAX98373_ALC5682I_I2S_UP4_VALUE 0x400 FW_CONFIG_FIELD_AUDIO_OPTION_MAX98360_ALC5682I_I2S_VALUE 0x500 FW_CONFIG_FIELD_AUDIO_OPTION_RT1011_ALC5682I_I2S_VALUE 0x600 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_FOO_VALUE 0x700 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BAR_VALUE 0x20000000 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_QUUX_VALUE 0x20000100 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BLAH1_VALUE 0x20000200 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BLAH2_VALUE 0x20000700 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BLAH3_VALUE 0x80000000 FW_CONFIG_FIELD_AUDIO_OPTION_AUDIO_BLAH4_VALUE 0xa0000700 Change-Id: I5ed76706347ee9642198efc77139abdc3af1b8a6 Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/52747 Reviewed-by: Duncan Laurie <duncan@iceblink.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

We all knew this was coming, 32 bits is never enough. Doing this early so that it doesn't affect too much code yet. Take care of every usage of fw_config throughout the codebase so the conversion is all done at once.

2020-08-19arch/arm: Enable FIT payloadsSam Lewis
Implements fit_payload_arch for the arm (aarch32) architecture, so that FIT images can be used. The implementation is very similar to the existing implementations for arm64 and riscv, and has mostly been lifted from these other ports. TEST: Booted Beaglebone Black (in progress port, to be submitted soon!) with a FIT image containing a 5.4 kernel, dtb and initramfs.

2020-06-02fw_config: Add firmware configuration interfaceDuncan Laurie
This change introduces a new top-level interface for interacting with a bitmask providing firmware configuration information. This is motivated by Chromebook mainboards that need to support multiple different configurations at runtime with the same BIOS. In these devices the Embedded Controller provides a bitmask that can be broken down into different fields and each field can then be broken down into different options. The firmware configuration value could also be stored in CBFS and this interface will look in CBFS first to allow the Embedded Controller value to be overridden. The firmware configuration interface is intended to easily integrate into devicetree.cb and lead to less code duplication for new mainboards that make use of this feature. BUG=b:147462631 TEST=this provides a new interface that is tested in subsequent commits Change-Id: I1e889c235a81545e2ec0e3a34dfa750ac828a330 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/41209 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
