104 The Extended Industry Standard Architecture (EISA) bus was
105 developed as an open alternative to the IBM MicroChannel bus.

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

1316 PL310 implements the Clean & Invalidate by Way L2 cache maintenance
1317 operation (offset 0x7FC). This operation runs in background so that
1318 PL310 can handle normal accesses while it is in progress. Under very
1319 rare circumstances, due to this erratum, write data can be lost when
1320 PL310 treats a cacheable write transaction during a Clean &

1353
1354 Under some condition the effect of cache sync operation on
1355 the store buffer still remains when the operation completes.
1356 This means that the store buffer is always asked to drain and
1357 this prevents it from merging any further writes. The workaround
1358 is to replace the normal offset of cache sync operation (0x730)
1359 by another offset targeting an unmapped PL310 register 0x740.
1360 This has the same effect as the cache sync operation: store buffer
1361 drain and waiting for all buffers empty.

1690 Various binutils versions can resolve Thumb-2 branches to
1691 locally-defined, preemptible global symbols as short-range "b.n"
1692 branch instructions.
1693
1694 This is a problem, because there's no guarantee the final
1695 destination of the symbol, or any candidate locations for a
1696 trampoline, are within range of the branch. For this reason, the
1697 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1698 relocation in modules at all, and it makes little sense to add
1699 support.
1700
1701 The symptom is that the kernel fails with an "unsupported
1702 relocation" error when loading some modules.
1703
1704 Until fixed tools are available, passing
1705 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1706 code which hits this problem, at the cost of a bit of extra runtime

2065 Execute-In-Place allows the kernel to run from non-volatile storage
2066 directly addressable by the CPU, such as NOR flash. This saves RAM
2067 space since the text section of the kernel is not loaded from flash
2068 to RAM. Read-write sections, such as the data section and stack,
2069 are still copied to RAM. The XIP kernel is not compressed since
2070 it has to run directly from flash, so it will take more space to
2071 store it. The flash address used to link the kernel object files,
2072 and for storing it, is configuration dependent. Therefore, if you
2073 say Y here, you must know the proper physical address where to
2074 store the kernel image depending on your own flash memory usage.

2076 Also note that the make target becomes "make xipImage" rather than
2077 "make zImage" or "make Image". The final kernel binary to put in
