2010-08-05davinci: dm646x EVM: Specify reserved EDMA channel/slotsRajashekhara, Sudhakar
Not all the channels and slots available on the DM646x EVM are used by the devices on the EVM. These resources can be used by the DSP to speed up codec operations.

The drivers on da8xx/omapl EVMs do not utilize all the channels and slots provided by EDMA. Some of these are better utilitzed by the DSP on the SoC for speeding up codec operations.

2010-08-05davinci: support for EDMA resource sharingRajashekhara, Sudhakar
Current EDMA driver is not taking care of EDMA channels/slots which are allocated from other processor, say DSP. If a channel/slot is allocated from DSP, the existing EDMA driver can still allocate the same resource on ARM. This patch enables the user to pass the channel/slots reserved for DSP as platform data. EDMA driver scans this list during probe and prepares a bitmap of channel/slots which can be used on ARM side. Trying to reserve channels by doing a 'pre-allocate' using edma_alloc_{slot|channel}() API does not work because 1) The reservation should be done in probe() to avoid race with other ARM side driver trying to use EDMA 2) The alloc channel API sets up the access through shadow region 0 which will be incorrect for DSP usage. It also sets up the channel <-> queue number mapping which is not required as DSP will likely do its own mapping anyway. 3) (minor) There is no API to allocate channels in bulk.

2010-08-05davinci: edma: provide ability to detect insufficient CC info dataSekhar Nori
This patch modifies the EDMA driver to expect the channel controller (CC) infomation passed on by the platform as a fixed size (EDMA_MAX_CC) array of pointers to structures. Doing so helps catch errors of the sort where the resource structure has information for more channel controllers than the number channel controller info structures defined. Such insufficient platform data would lead to illegal memory accesses. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-08-05davinci: da8xx: sparse cleanup: remove duplicate entries in irq prioritiesSekhar Nori
This patch helps get rid of the following sparse warnings of the type: CHECK arch/arm/mach-davinci/da830.c arch/arm/mach-davinci/da830.c:1026:3: warning: Initializer entry defined twice arch/arm/mach-davinci/da830.c:1027:3: also defined here coming from the irq priorities array init. Apart from one instance of genuinie repetition, most are are instances of multiple #defines of the same interrupt number. I have not removed the multiple definitions from the irq.h file in the hope that someone might decide to use them as shared interrupts at some point of time.

We reserve the 3.75GB - 4GB region of PCIe address space for device to device transfers, making the corresponding physical memory under direct mapping unavailable for DMA. To allow for PCIe DMA to all physical memory we map this chunk of physical memory with BAR1. Because of the resulting discontinuity in the mapping function, we remove a page of memory at each end of the range so multi-page DMA buffers can never be allocated that span the range.

This patch is based on previous work by Sony and Himanshu Chauhan. I have done some cleanup and implemented JProbes and KRETPROBES. The KRETPROBES part is pretty much copied verbatim from powerpc. A possible future enhance might be to factor out the common code.
