105 The Extended Industry Standard Architecture (EISA) bus was

108 The EISA bus provided some of the features of the IBM MicroChannel
109 bus while maintaining backward compatibility with cards made for
110 the older ISA bus. The EISA bus saw limited use between 1988 and
111 1995 when it was made obsolete by the PCI bus.

1341 Under some condition the effect of cache sync operation on
1342 the store buffer still remains when the operation completes.
1343 This means that the store buffer is always asked to drain and
1344 this prevents it from merging any further writes. The workaround
1345 is to replace the normal offset of cache sync operation (0x730)
1346 by another offset targeting an unmapped PL310 register 0x740.
1347 This has the same effect as the cache sync operation: store buffer
1348 drain and waiting for all buffers empty.

1683 Various binutils versions can resolve Thumb-2 branches to
1684 locally-defined, preemptible global symbols as short-range "b.n"
1685 branch instructions.
1686
1687 This is a problem, because there's no guarantee the final
1688 destination of the symbol, or any candidate locations for a
1689 trampoline, are within range of the branch. For this reason, the
1690 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1691 relocation in modules at all, and it makes little sense to add
1692 support.
1693
1694 The symptom is that the kernel fails with an "unsupported
1695 relocation" error when loading some modules.
1696
1697 Until fixed tools are available, passing
1698 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1699 code which hits this problem, at the cost of a bit of extra runtime
1700 stack usage in some cases.

2058 Execute-In-Place allows the kernel to run from non-volatile storage
2059 directly addressable by the CPU, such as NOR flash. This saves RAM
2060 space since the text section of the kernel is not loaded from flash
2061 to RAM. Read-write sections, such as the data section and stack,
2062 are still copied to RAM. The XIP kernel is not compressed since
2063 it has to run directly from flash, so it will take more space to
2064 store it. The flash address used to link the kernel object files,
2065 and for storing it, is configuration dependent. Therefore, if you
2066 say Y here, you must know the proper physical address where to
2067 store the kernel image depending on your own flash memory usage.

2069 Also note that the make target becomes "make xipImage" rather than
2070 "make zImage" or "make Image". The final kernel binary to put in
