A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

Say Y to support the Acorn Archimedes.

The Acorn Archimedes was an personal computer based on an 8MHz ARM2

|
|
later models and floppy, harddisc, ethernet etc.

---help---
|

Say Y to include the NWFPE floating point emulator in the kernel.
|
|
This is necessary to run most binaries. Linux does not currently
|
|
support floating point hardware so you need to say Y here even if
|
|
your machine has an FPA or floating point co-processor podule.
|
|
|
|
It is also possible to say M to build the emulator as a module
|
|
(nwfpe) or indeed to leave it out altogether. However, unless you
|
|
know what you are doing this can easily render your machine
|
|
unbootable. Saying Y is the safe option.
|
|
|
|
You may say N here if you are going to load the Acorn FPEmulator
|
|
early in the bootup.

help
|
|
This option reduces the latency of the kernel when reacting to
|
|
real-time or interactive events by allowing a low priority process to
|
|
be preempted even if it is in kernel mode executing a system call.
|
|
This allows applications to run more reliably even when the system is
|
|
under load.
|
|
|
|
Say Y here if you are building a kernel for a desktop, embedded
|
|
or real-time system. Say N if you are unsure.

Acorn RISC OS/Arthur binaries under Linux. This code is still very

You can also say M here to compile this support as a module (which

On some architectures (EBSA110 and CATS), there is currently no way
|
|
for the boot loader to pass arguments to the kernel. For these
|
|
architectures, you should supply some command-line options at build
|
|
time by entering them here. As a minimum, you should specify the
|
|
memory size and the root device (e.g., mem=64M root=/dev/nfs).
