When printk() is disabled (CONFIG_PRINTK) at menu item
General setup
- Configure standard kernel features (for small systems)
- Enable support for printk
then there should be no printk() calls at all.

Hi Per-Erik,
I found your message at
http://lists.ozlabs.org/pipermail/linuxppc-dev/2007-December/048539.html
back from Dec 2007.
Have you managed to run Linux on phyCORE-MPC5554 since then?

Hi
I'm wondering if someone has ever tried to get Linux running on a
The following patch series adds USB 2.0 support for the Wii PowerPC
platform via the EHCI controller present in the Hollywood chipset
of the video game console.
v2 - v3
- use per-device dma coherent support to allocate coherent MEM2 memory
- add support for SWIOTLB on NOT_COHERENT_CACHE PowerPC
Use the generic per-device dma coherent allocator on powerpc.
This allows a driver to declare coherent memory area from where
a device can allocate coherent memory chunks.

This patch makes swiotlb_alloc_boot() available again.
This weak function can be overloaded to modify slightly how the SWIOTLB
and the overflow areas are allocated during boot.
This will be used later to support the Nintendo Wii video game console,
which requires placing the SWIOTLB area above
The current SWIOTLB code does not support NOT_COHERENT_CACHE platforms.
This patch adds support for NOT_COHERENT_CACHE platforms to SWIOTLB by
adding two platform specific functions swiotlb_dma_sync_page() and
swiotlb_dma_sync() which can be used to explicitly manage cache coherency.
On PowerPC
The current SWIOTLB code uses a default of 64MB for the IO TLB area.
This size can be influenced using a kernel command line parameter swiotlb.
Unfortunately, the parsing of the kernel command line is done _after_ the
swiotlb is initialized on some architectures.
This patch adds a new function
Split unmap_urb_for_dma() and map_urb_for_dma() into smaller pieces
to make the code easier to read and maintain.
This patch adds four new URB flags which are used by map_urb_for_dma()
to mark URBs with the exact method used to map the setup packet and/or the
transfer buffer.
These flags are
Some of the devices in the Hollywood chipset of the Nintendo Wii video
game console have restrictions performing DMA transfers to the first
contiguous RAM region (known as MEM1).
For example, up to 3 bytes of the last word of a DMA transfer of a
non-32 bit aligned length to MEM1 may be lost.
Such

This is used by the platform DMA support code to overcome the limitations
found in some of the devices within the Hollywood chipset.

The HCD_NO_COHERENT_MEM USB host controller driver flag can be enabled
to instruct the USB stack to avoid allocating coherent memory for USB
buffers.
This flag is useful to overcome some esoteric memory access restrictions
found in some platforms.
For example, the Nintendo Wii video game console
Let the Nintendo Wii gaming console use per-device dma coherent allocations.
This will be used later by some of its drivers.

Hi all,
I recently posted a patch which improves the baud rate calculation on the

also affect the mpc512x.
