22 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 23 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 24 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 25 | manufactured, but legacy ARM-based PC hardware remains popular in |

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

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

1310 | Execute-In-Place allows the kernel to run from non-volatile storage | |
1311 | directly addressable by the CPU, such as NOR flash. This saves RAM | |
1312 | space since the text section of the kernel is not loaded from flash | |
1313 | to RAM. Read-write sections, such as the data section and stack, | |
1314 | are still copied to RAM. The XIP kernel is not compressed since | |
1315 | it has to run directly from flash, so it will take more space to | |
1316 | store it. The flash address used to link the kernel object files, | |
1317 | and for storing it, is configuration dependent. Therefore, if you | |
