This is useful in general 707 as most CPUs have a fairly sparse array of IRQ vectors, which 708 the irq_desc then maps directly on to. Systems with a high 709 number of off-chip IRQs will want to treat this as 710 experimental until they have been independently verified. 711 712 If you don't know what to do here, say N. 713 714endmenu 715 716menu "Boot options" 717 718config ZERO_PAGE_OFFSET 719 hex 720 default "0x00010000" if PAGE_SIZE_64KB || SH_RTS7751R2D || \ 721 SH_7751_SOLUTION_ENGINE 722 default "0x00004000" if PAGE_SIZE_16KB || SH_SH03 723 default "0x00002000" if PAGE_SIZE_8KB 724 default "0x00001000" 725 help 726 This sets the default offset of zero page. 727 728config BOOT_LINK_OFFSET 729 hex 730 default "0x00210000" if SH_SHMIN 731 default "0x00400000" if SH_CAYMAN 732 default "0x00810000" if SH_7780_SOLUTION_ENGINE 733 default "0x009e0000" if SH_TITAN 734 default "0x01800000" if SH_SDK7780 735 default "0x02000000" if SH_EDOSK7760 736 default "0x00800000" 737 help 738 This option allows you to set the link address offset of the zImage. 739 This can be useful if you are on a board which has a small amount of 740 memory. 741 742config ENTRY_OFFSET 743 hex 744 default "0x00001000" if PAGE_SIZE_4KB 745 default "0x00002000" if PAGE_SIZE_8KB 746 default "0x00004000" if PAGE_SIZE_16KB 747 default "0x00010000" if PAGE_SIZE_64KB 748 default "0x00000000" 749 750config UBC_WAKEUP 751 bool "Wakeup UBC on startup" 752 depends on CPU_SH4 && !CPU_SH4A 753 help 754 Selecting this option will wakeup the User Break Controller (UBC) on 755 startup.
