Only enable this option if you do not want debug capabilities in case of system fatal error. # # End hidden PM feature configs # config ARCH string help System architecture string. config SOC string help SoC name which can be found under arch/<arch>/soc/<soc name>. This option holds the directory name used by the build system to locate the correct linker and header files for the SoC. This option will go away once all SoCs are using family/series structure. config SOC_SERIES string help SoC series name which can be found under arch/<arch>/soc/<family>/<series>. This option holds the directory name used by the build system to locate the correct linker and header files. config SOC_FAMILY string help SoC family name which can be found under arch/<arch>/soc/<family>. This option holds the directory name used by the build system to locate the correct linker and header files. config BOARD string help This option holds the name of the board and is used to locate the files related to the board in the source tree (under boards/). The Board is the first location where we search for a linker.ld file, if not found we look for the linker file in arch/<arch>/soc/<family>/<series> # # Interrupt related configs # config GEN_ISR_TABLES bool prompt "Use generated IRQ tables" default n help This option controls whether a platform uses the gen_isr_tables script to generate its interrupt tables. This mechanism will create an appropriate hardware vector table and/or software IRQ table. config GEN_IRQ_VECTOR_TABLE bool prompt "Generate an interrupt vector table" default y depends on GEN_ISR_TABLES help This option controls whether a platform using gen_isr_tables needs an interrupt vector table created. Only disable this if the platform does not use a vector table at all, or requires the vector table to be in a format that is not an array of function pointers indexed by IRQ line. In the latter case, the vector table must be supplied by the application or architecture code. config GEN_SW_ISR_TABLE bool prompt "Generate a software ISR table" default y depends on GEN_ISR_TABLES help This option controls whether a platform using gen_isr_tables needs a software ISR table table created. This is an array of struct _isr_table_entry containing the interrupt service routine and supplied parameter. config GEN_IRQ_START_VECTOR int default 0 depends on GEN_ISR_TABLES help On some architectures, part of the vector table may be reserved for system exceptions and is declared separately from the tables created by gen_isr_tables.py. When creating these tables, this value will be subtracted from CONFIG_NUM_IRQS to properly size them. This is a hidden option which needs to be set per architecture and left alone. source "arch/*/Kconfig" source "boards/Kconfig" |
