32 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 33 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 34 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 35 | manufactured, but legacy ARM-based PC hardware remains popular in |
1da177e4 LT |
36 | Europe. There is an ARM Linux project with a web page at |

78 | ---help--- | |
79 | The Extended Industry Standard Architecture (EISA) bus was | |
80 | developed as an open alternative to the IBM MicroChannel bus. | |
81 | ||
82 | The EISA bus provided some of the features of the IBM MicroChannel | |
83 | bus while maintaining backward compatibility with cards made for | |
84 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
85 | 1995 when it was made obsolete by the PCI bus. | |
86 | ||
87 | Say Y here if you are building a kernel for an EISA-based machine. | |

1650 | help | |
1651 | Execute-In-Place allows the kernel to run from non-volatile storage | |
1652 | directly addressable by the CPU, such as NOR flash. This saves RAM | |
1653 | space since the text section of the kernel is not loaded from flash | |
1654 | to RAM. Read-write sections, such as the data section and stack, | |
1655 | are still copied to RAM. The XIP kernel is not compressed since | |
1656 | it has to run directly from flash, so it will take more space to | |
