More information on Qemu 56207119621SRalf Baechle can be found at http://www.linux-mips.org/wiki/Qemu. 56307119621SRalf Baechle 564355c471fSdmitry pervushinconfig MARKEINS 565355c471fSdmitry pervushin bool "Support for NEC EMMA2RH Mark-eins" 566355c471fSdmitry pervushin select DMA_NONCOHERENT 567355c471fSdmitry pervushin select HW_HAS_PCI 568355c471fSdmitry pervushin select IRQ_CPU 569355c471fSdmitry pervushin select SWAP_IO_SPACE 570355c471fSdmitry pervushin select SYS_SUPPORTS_32BIT_KERNEL 571355c471fSdmitry pervushin select SYS_SUPPORTS_BIG_ENDIAN 572355c471fSdmitry pervushin select SYS_SUPPORTS_LITTLE_ENDIAN 573355c471fSdmitry pervushin select SYS_HAS_CPU_R5000 574355c471fSdmitry pervushin help 575355c471fSdmitry pervushin This enables support for the R5432-based NEC Mark-eins 576355c471fSdmitry pervushin boards with R5500 CPU. 577355c471fSdmitry pervushin 5781da177e4SLinus Torvaldsconfig SGI_IP22 5793fa986faSMartin Michlmayr bool "SGI IP22 (Indy/Indigo2)" 5801da177e4SLinus Torvalds select ARC 5811da177e4SLinus Torvalds select ARC32 5821da177e4SLinus Torvalds select BOOT_ELF32 5831da177e4SLinus Torvalds select DMA_NONCOHERENT 5845e83d430SRalf Baechle select HW_HAS_EISA 5851da177e4SLinus Torvalds select IP22_CPU_SCACHE 5861da177e4SLinus Torvalds select IRQ_CPU 587aac076f8SRalf Baechle select NO_ISA if ISA 5881da177e4SLinus Torvalds select SWAP_IO_SPACE 5897cf8053bSRalf Baechle select SYS_HAS_CPU_R4X00 5907cf8053bSRalf Baechle select SYS_HAS_CPU_R5000 591ed5ba2fbSYoichi Yuasa select SYS_SUPPORTS_32BIT_KERNEL 592ed5ba2fbSYoichi Yuasa select SYS_SUPPORTS_64BIT_KERNEL 5935e83d430SRalf Baechle select SYS_SUPPORTS_BIG_ENDIAN 594*e73ea273SRalf Baechle select SYS_SUPPORTS_SMP 5951da177e4SLinus Torvalds help 5961da177e4SLinus Torvalds This are the SGI Indy, Challenge S and Indigo2, as well as certain 5971da177e4SLinus Torvalds OEM variants like the Tandem CMN B006S.
