1184 | MIPS64 architecture. Many modern embedded systems with a 64-bit | |

1196 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1197 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1198 | *not* work on R4000 machines and vice versa. However, since most | |
1199 | of the supported machines have an R4000 (or similar) CPU, R4x00 | |
1200 | might be a safe bet. If the resulting kernel does not work, | |
1201 | try to recompile with R3000. | |

2049 | help |
2050 | A 64-bit kernel is usually built using the 64-bit ELF binary object | |
2051 | format as it's one that allows arbitrary 64-bit constructs. For | |
2052 | kernels that are loaded within the KSEG compatibility segments the | |
2053 | 32-bit ELF format can optionally be used resulting in a somewhat | |
2054 | smaller binary, but this option is not explicitly supported by the | |
2055 | toolchain and since binutils 2.14 it does not even work at all. | |
2056 | ||
2057 | Say Y to use the 64-bit format or N to use the 32-bit one. | |
2058 | ||
