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

99 The EISA bus provided some of the features of the IBM MicroChannel
100 bus while maintaining backward compatibility with cards made for
101 the older ISA bus. The EISA bus saw limited use between 1988 and
102 1995 when it was made obsolete by the PCI bus.

1305 PL310 implements the Clean & Invalidate by Way L2 cache maintenance
1306 operation (offset 0x7FC). This operation runs in background so that
1307 PL310 can handle normal accesses while it is in progress. Under very
1308 rare circumstances, due to this erratum, write data can be lost when
1309 PL310 treats a cacheable write transaction during a Clean &

1340
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.

1402 On revisions of the PL310 prior to r3p2, the Store Buffer does

1406 This option adds a write barrier to the cpu_idle loop so that,

1408 explicitly.

1656 locally-defined, preemptible global symbols as short-range "b.n"
1657 branch instructions.
1658
1659 This is a problem, because there's no guarantee the final
1660 destination of the symbol, or any candidate locations for a
1661 trampoline, are within range of the branch. For this reason, the
1662 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1663 relocation in modules at all, and it makes little sense to add
1664 support.
1665
1666 The symptom is that the kernel fails with an "unsupported
1667 relocation" error when loading some modules.
1668
1669 Until fixed tools are available, passing
1670 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1671 code which hits this problem, at the cost of a bit of extra runtime
1672 stack usage in some cases.
1673
1674 The problem is described in more detail at:
1675 https://bugs.launchpad.net/binutils-linaro/+bug/725126

1677 Only Thumb-2 kernels are affected.

1706 intercept syscalls that have structure arguments which layout
1707 in memory differs between the legacy ABI and the new ARM EABI

2059 Execute-In-Place allows the kernel to run from non-volatile storage
2060 directly addressable by the CPU, such as NOR flash. This saves RAM
2061 space since the text section of the kernel is not loaded from flash
2062 to RAM. Read-write sections, such as the data section and stack,
2063 are still copied to RAM. The XIP kernel is not compressed since
2064 it has to run directly from flash, so it will take more space to
2065 store it. The flash address used to link the kernel object files,
2066 and for storing it, is configuration dependent. Therefore, if you
2067 say Y here, you must know the proper physical address where to
2068 store the kernel image depending on your own flash memory usage.
2069
2070 Also note that the make target becomes "make xipImage" rather than
2071 "make zImage" or "make Image". The final kernel binary to put in
