Hello everyone,
This is the second posting of these drivers, taking into account comments
from the RFCv1 post. Thanks to all that contributed.
The changes:
- change comments to kerneldoc format
- Kconfig improvements
- use the videobuf_dma_sg API in the programmer
- updates for Freescale DMAEngin
The slab.h header is required to use the kmalloc() family of functions.
Due to recent kernel changes, this header must be directly included by
code that calls into the memory allocator.

The DMA_SLAVE support functions all existed as static inlines in the
driver specific header arch/powerpc/include/asm/fsldma.h. Move the body
of the functions to the driver itself, and EXPORT_SYMBOL_GPL() them.
At the same time, add the missing linux/list.h header.

This adds basic support for the system controller FPGA on the OVRO CARMA
board. This patch only adds infrastructure that will be used by later

This driver allows userspace to access the data processing FPGAs on the
OVRO CARMA board. It has two modes of operation:
1) random access
This allows users to poke any DATA-FPGA registers by using mmap to map
the address region directly into their memory map.

This adds support for programming the data processing FPGAs on the OVRO
CARMA board. These FPGAs have a special programming sequence that
requires that we program the Freescale DMA engine, which is only
available inside the kernel.

Hello everyone,
I'm running Linux on a Freescale MPC8349EA board (PowerPC 6xx processor). When
I enable the CONFIG_PROVE_LOCKING option, the kernel fails to boot. If I

The lockup happens very, very early during boot. Much t

Linus made a suggestion to that effect? If so, I missed it. Have a

Are arch/powerpc/configs/ppc44x_defconfig and ppc40x_defconfig what you want?
Or do you mean the Kconfig based versions?

There was discussion going on in arm-kernel mailing list. And I see some
patches being submitted for ARM based boards.
I think we can also combine some of the defconfigs under
arch/powerpc/configs/44x/ directory.
