24 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 25 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 26 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 27 | manufactured, but legacy ARM-based PC hardware remains popular in |

61 | The Extended Industry Standard Architecture (EISA) bus was | |
62 | developed as an open alternative to the IBM MicroChannel bus. | |
63 | ||
64 | The EISA bus provided some of the features of the IBM MicroChannel | |
65 | bus while maintaining backward compatibility with cards made for | |
66 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
67 | 1995 when it was made obsolete by the PCI bus. | |

885 | help | |
886 | This option enables the workaround for the 430973 Cortex-A8 | |
887 | (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb | |
888 | interworking branch is replaced with another code sequence at the | |
889 | same virtual address, whether due to self-modifying code or virtual | |
890 | to physical address re-mapping, Cortex-A8 does not recover from the | |
891 | stale interworking branch prediction. This results in Cortex-A8 | |
892 | executing the new code sequence in the incorrect ARM or Thumb state. | |
893 | The workaround enables the BTB/BTAC operations by setting ACTLR.IBE | |
894 | and also flushes the branch target cache at every context switch. | |

1308 | Execute-In-Place allows the kernel to run from non-volatile storage | |
1309 | directly addressable by the CPU, such as NOR flash. This saves RAM | |
1310 | space since the text section of the kernel is not loaded from flash | |
1311 | to RAM. Read-write sections, such as the data section and stack, | |
1312 | are still copied to RAM. The XIP kernel is not compressed since | |
1313 | it has to run directly from flash, so it will take more space to | |
1314 | store it. The flash address used to link the kernel object files, | |
1315 | and for storing it, is configuration dependent. Therefore, if you | |
