| help |
| Specify if the board configuration should be treated as a simulator. |

| help |
| This option specifies hardware clock. |

| bool "Core has no IPC support" |
| select ATOMIC_OPERATIONS_C |
| default n |
| help |
| Uncheck this if you core does not implement "SCOMPARE1" register and "s32c1i" |
| instruction. |
| |
| config SW_ISR_TABLE |
| bool |
| prompt "Enable software interrupt handler table" |
| default y |
| help |
| Enable an interrupt handler table implemented in software. This |
| table, unlike ISRs connected directly in the vector table, allow |
| a parameter to be passed to the interrupt handlers. Also, invoking |
| the exception/interrupt exit stub is automatically done. |
| |
| config IRQ_OFFLOAD |
| bool "Enable IRQ offload" |
| default n |
| help |
| Enable irq_offload() API which allows functions to be synchronously |
| run in interrupt context. Uses one entry in the IDT. Mainly useful |
| for test cases. |
| |
| config XTENSA_RESET_VECTOR |
| bool |
| prompt "Build reset vector code" |
| default y |
| help |
| This option controls whether the initial reset vector code is built. |
| This is always needed for the simulator. Real boards may already |
| implement this in boot ROM. |
| |
| config XTENSA_USE_CORE_CRT1 |
| bool |
| prompt "Use crt1.S from core" |
| default y |

| SoC or boards might define their own __start by setting this setting |
| to false. |

| int |
| prompt "IRQ offload SW interrupt index" |
| help |
| The index of the software interrupt to be used for IRQ offload. |
| |
| Please note that in order for IRQ offload to work correctly the selected |
| interrupt shall have its priority shall not exceed XCHAL_EXCM_LEVEL. |
