55 | The Extended Industry Standard Architecture (EISA) bus was | |
56 | developed as an open alternative to the IBM MicroChannel bus. | |
57 | ||
58 | The EISA bus provided some of the features of the IBM MicroChannel | |
59 | bus while maintaining backward compatibility with cards made for | |
60 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
61 | 1995 when it was made obsolete by the PCI bus. | |

901 | Execute-In-Place allows the kernel to run from non-volatile storage | |
902 | directly addressable by the CPU, such as NOR flash. This saves RAM | |
903 | space since the text section of the kernel is not loaded from flash | |
904 | to RAM. Read-write sections, such as the data section and stack, | |
905 | are still copied to RAM. The XIP kernel is not compressed since | |
906 | it has to run directly from flash, so it will take more space to | |
907 | store it. The flash address used to link the kernel object files, | |
908 | and for storing it, is configuration dependent. Therefore, if you | |
909 | say Y here, you must know the proper physical address where to | |
910 | store the kernel image depending on your own flash memory usage. | |
