Some builds of m32r were failing as it tried to build few drivers which needed dma but m32r is not having dma support. Objections were raised when it was tried to make those drivers depend on HAS_DMA. So the next best thing is to add dma support to m32r. dma_noop is a very simple dma with 1:1 memory mapping.

The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
|
|
You can operate a Linux system on this board by using an M32R
|
|
softmacro core, which is a fully-synthesizable functional model
|
|
described in Verilog-HDL.
|
|
|
|
The Mappi-I board was the first platform, which had been used
|
|
to port and develop a Linux system for the M32R processor.
|
|
Currently, the Mappi-II, an heir to the Mappi-I, is available.

On PCI systems, the BIOS can be used to detect the PCI devices and

|
determine their configuration. However, some old PCI motherboards
|
|
have BIOS bugs and may crash if this is done. Also, some embedded
|
|
PCI-based systems don't have any BIOS at all. Linux can also try to

|
detect the PCI hardware directly without using the BIOS.
|
|
|
|
With this option, you can specify how Linux should detect the PCI

|
devices. If you choose "BIOS", the BIOS will be used, if you choose
|
|
"Direct", the BIOS won't be used, and if you choose "Any", the
|
|
kernel will try the direct access method and falls back to the BIOS
|

if that doesn't work. If unsure, go with the default, which is

"Any".
