| select CPU_32v4T |
| help |
| The ARM920T is licensed to be produced by numerous vendors, |
| and is used in the Maverick EP9312 and the Samsung S3C2410. |
| |
| More information on the Maverick EP9312 at |
| <http://linuxdevices.com/products/PD2382866068.html>. |

| Say Y if you want support for the ARM920T processor. |
| Otherwise, say N. |

| select CPU_32v5 |
| help |
| This is a variant of the ARM920. It has slightly different |
| instruction sequences for cache and TLB operations. Curiously, |
| there is no documentation on it at the ARM corporate website. |

| bool "Build big-endian kernel" |
| depends on ARCH_SUPPORTS_BIG_ENDIAN |
| help |
| Say Y if you plan on running a kernel in big-endian mode. |
| Note that your board must be properly built and your board |
| port must properly enable any big-endian related features |
| of your chipset/board/processor. |
| |
| config BOOT_ENDIANNESS_SWITCH |
| bool "Support switching of Linux kernel endianness" |
| help |
| Say Y here if you need to switch CPU endianness before running |
| Linux kernel, e.g. if you want big-endian Barebox to run |
| little-endian Linux. |
| |
| Currently implemented only by "bootz" command. |
