Hi,
since there has been a thread on allowing the use of a coprocessor in
the kernel already: I am wondering if it'd make sense to use AltiVec for
AES in dm-crypt, and how difficult it would be to implement that.
I'm using a PegasosII which has a G4 running at 1 GHz; I get around 3
MB/s throughpu

It's not sufficient on PowerPC.
It might be necessary, depending on the compiler's mood f
Hi,
I just tried upgrading my PegasosII to 2.6.29, and found that the Marvell
driver shows two Ethernet ports now, one with a MAC address ending in
...:de:ad:01 (which is the port that is not wired to the outside), and the
other one with 00:00:00:00:00:00.
I think some sort of Pegasos specific ha

Doing that now, using the code you provided as a base. The SPI child

This. As far as I can see, using the device tree for this is currently
unsupported, and everyone who uses the mmc-spi driver just creates a
platform device in the board startup code, which strikes me as so
Hi,
in an embedded system similar to the lite5200 board, there is an MMC
card socket connected to one of the PSCs. Ideally, I'd like to express
this fact via the device tree and have the kernel bind the mmc-spi
driver to the SPI interface, but I cannot find any place where to insert
this code
