28 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 29 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 30 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 31 | manufactured, but legacy ARM-based PC hardware remains popular in |
1da177e4 LT |
32 | Europe. There is an ARM Linux project with a web page at |

72 | The Extended Industry Standard Architecture (EISA) bus was | |
73 | developed as an open alternative to the IBM MicroChannel bus. | |
74 | ||
75 | The EISA bus provided some of the features of the IBM MicroChannel | |
76 | bus while maintaining backward compatibility with cards made for | |
77 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
78 | 1995 when it was made obsolete by the PCI bus. | |
79 | ||
80 | Say Y here if you are building a kernel for an EISA-based machine. | |

1041 | This option enables the workaround for the 430973 Cortex-A8 | |

1043 | interworking branch is replaced with another code sequence at the | |

1610 | help | |
1611 | Execute-In-Place allows the kernel to run from non-volatile storage | |
1612 | directly addressable by the CPU, such as NOR flash. This saves RAM | |
1613 | space since the text section of the kernel is not loaded from flash | |
1614 | to RAM. Read-write sections, such as the data section and stack, | |
1615 | are still copied to RAM. The XIP kernel is not compressed since | |
1616 | it has to run directly from flash, so it will take more space to | |
1617 | store it. The flash address used to link the kernel object files, | |
1618 | and for storing it, is configuration dependent. Therefore, if you | |
1619 | say Y here, you must know the proper physical address where to | |
1620 | store the kernel image depending on your own flash memory usage. | |

1623 | "make zImage" or "make Image". The final kernel binary to put in | |
1624 | ROM memory will be arch/arm/boot/xipImage. | |
