          manufactured, but legacy ARM-based PC hardware remains popular in
          Europe.  There is an ARM Linux project with a web page at

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

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

          and have them programmed to occur as required. This option saves
          power as the system can remain in idle state for longer.

          By default dynamic tick is disabled during the boot, and can be
          manually enabled with:

            echo 1 > /sys/devices/system/timer/timer0/dyn_tick

          Alternatively, if you want dynamic tick automatically enabled
          during boot, pass "dyntick=enable" via the kernel command string.

          Please note that dynamic tick may affect the accuracy of
          timekeeping on some platforms depending on the implementation.
          Currently at least OMAP, PXA2xx and SA11x0 platforms are known

          This option allows for the kernel to be compiled using the latest
          ARM ABI (aka EABI).  This is only useful if you are using a user
          space environment that is also compiled with EABI.

          Since there are major incompatibilities between the legacy ABI and
          EABI, especially with regard to structure member alignment, this
          option also changes the kernel syscall calling convention to
          disambiguate both ABIs and allow for backward compatibility support
          (selected with CONFIG_OABI_COMPAT).

          To use this you need GCC version 4.0.0 or later.

          This option preserves the old syscall interface along with the
          new (ARM EABI) one. It also provides a compatibility layer to
          intercept syscalls that have structure arguments which layout
          in memory differs between the legacy ABI and the new ARM EABI
          (only for non "thumb" binaries). This option adds a tiny
          overhead to all syscalls and produces a slightly larger kernel.
          If you know you'll be using only pure EABI user space then you
          can say N here. If this option is not selected and you attempt
          to execute a legacy ABI binary then the result will be

          Execute-In-Place allows the kernel to run from non-volatile storage
          directly addressable by the CPU, such as NOR flash. This saves RAM

          to RAM.  Read-write sections, such as the data section and stack,
          are still copied to RAM.  The XIP kernel is not compressed since
          it has to run directly from flash, so it will take more space to
          store it.  The flash address used to link the kernel object files,
          and for storing it, is configuration dependent. Therefore, if you
