101 The Extended Industry Standard Architecture (EISA) bus was
102 developed as an open alternative to the IBM MicroChannel bus.
103
104 The EISA bus provided some of the features of the IBM MicroChannel
105 bus while maintaining backward compatibility with cards made for
106 the older ISA bus. The EISA bus saw limited use between 1988 and
107 1995 when it was made obsolete by the PCI bus.
108
109 Say Y here if you are building a kernel for an EISA-based machine.

1303 PL310 implements the Clean & Invalidate by Way L2 cache maintenance

1305 PL310 can handle normal accesses while it is in progress. Under very
1306 rare circumstances, due to this erratum, write data can be lost when
1307 PL310 treats a cacheable write transaction during a Clean &

1338
1339 Under some condition the effect of cache sync operation on
1340 the store buffer still remains when the operation completes.
1341 This means that the store buffer is always asked to drain and
1342 this prevents it from merging any further writes. The workaround
1343 is to replace the normal offset of cache sync operation (0x730)
1344 by another offset targeting an unmapped PL310 register 0x740.
1345 This has the same effect as the cache sync operation: store buffer
1346 drain and waiting for all buffers empty.

1663 help
1664 Various binutils versions can resolve Thumb-2 branches to
1665 locally-defined, preemptible global symbols as short-range "b.n"
1666 branch instructions.
1667
1668 This is a problem, because there's no guarantee the final
1669 destination of the symbol, or any candidate locations for a
1670 trampoline, are within range of the branch. For this reason, the
1671 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1672 relocation in modules at all, and it makes little sense to add
1673 support.
1674
1675 The symptom is that the kernel fails with an "unsupported
1676 relocation" error when loading some modules.
1677
1678 Until fixed tools are available, passing
1679 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1680 code which hits this problem, at the cost of a bit of extra runtime
1681 stack usage in some cases.

2038 Execute-In-Place allows the kernel to run from non-volatile storage
2039 directly addressable by the CPU, such as NOR flash. This saves RAM
2040 space since the text section of the kernel is not loaded from flash
2041 to RAM. Read-write sections, such as the data section and stack,
2042 are still copied to RAM. The XIP kernel is not compressed since
2043 it has to run directly from flash, so it will take more space to
2044 store it. The flash address used to link the kernel object files,
2045 and for storing it, is configuration dependent. Therefore, if you
2046 say Y here, you must know the proper physical address where to
2047 store the kernel image depending on your own flash memory usage.
2048
2049 Also note that the make target becomes "make xipImage" rather than
2050 "make zImage" or "make Image". The final kernel binary to put in
2051 ROM memory will be arch/arm/boot/xipImage.

2068 kexec is a system call that implements the ability to shutdown your
2069 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002070 but it is independent of the system firmware. And like a reboot
Richard Purdiec587e4a2007-02-06 21:29:00 +01002071 you can start any kernel with it, not just Linux.
2072
2073 It is an ongoing process to be certain the hardware in a machine
2074 is properly shutdown, so do not be surprised if this code does not
2075 initially work for you. It may help to enable device hotplugging
2076 support.
