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

94 The EISA bus provided some of the features of the IBM MicroChannel
95 bus while maintaining backward compatibility with cards made for
96 the older ISA bus. The EISA bus saw limited use between 1988 and
97 1995 when it was made obsolete by the PCI bus.

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.

1683 This option allows for the kernel to be compiled using the latest
1684 ARM ABI (aka EABI). This is only useful if you are using a user
1685 space environment that is also compiled with EABI.
1686
1687 Since there are major incompatibilities between the legacy ABI and
1688 EABI, especially with regard to structure member alignment, this
1689 option also changes the kernel syscall calling convention to
1690 disambiguate both ABIs and allow for backward compatibility support
1691 (selected with CONFIG_OABI_COMPAT).
1692
1693 To use this you need GCC version 4.0.0 or later.

1700 This option preserves the old syscall interface along with the
1701 new (ARM EABI) one. It also provides a compatibility layer to
1702 intercept syscalls that have structure arguments which layout
1703 in memory differs between the legacy ABI and the new ARM EABI
1704 (only for non "thumb" binaries). This option adds a tiny
1705 overhead to all syscalls and produces a slightly larger kernel.
1706 If you know you'll be using only pure EABI user space then you
1707 can say N here. If this option is not selected and you attempt
1708 to execute a legacy ABI binary then the result will be
1709 UNPREDICTABLE (in fact it can be predicted that it won't work
1710 at all). If in doubt say Y.

1732 and it has to accommodate user address space, kernel address
1733 space as well as some memory mapped IO. That means that, if you

1736 memory that is not permanently mapped is called "high memory".

2039 to RAM. Read-write sections, such as the data section and stack,
2040 are still copied to RAM. The XIP kernel is not compressed since
2041 it has to run directly from flash, so it will take more space to
2042 store it. The flash address used to link the kernel object files,
2043 and for storing it, is configuration dependent. Therefore, if you
2044 say Y here, you must know the proper physical address where to
2045 store the kernel image depending on your own flash memory usage.

2047 Also note that the make target becomes "make xipImage" rather than
2048 "make zImage" or "make Image". The final kernel binary to put in

2066 kexec is a system call that implements the ability to shutdown your
2067 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002068 but it is independent of the system firmware. And like a reboot
Richard Purdiec587e4a2007-02-06 21:29:00 +01002069 you can start any kernel with it, not just Linux.
2070
2071 It is an ongoing process to be certain the hardware in a machine
2072 is properly shutdown, so do not be surprised if this code does not
2073 initially work for you. It may help to enable device hotplugging
2074 support.
