* [POWERPC] MPC832x_RDB: Update dts to use SPI1 in QE, register mmc_spi stubAnton Vorontsov2007-09-142-1/+47
| | | | | | | | | | | Enabled using SPI controller on the MPC832x RDB board. We currently use a modalias of "spidev" as a place holder (replace with "mmc_spie") until the mmc_spi driver support is merged in. This gets us the ability to test SPI until then.

* [POWERPC] 86xx: Fix definition of global-utilites structureTimur Tabi2007-09-141-105/+46
| | | | | | | | | The current definition of struct ccsr_guts in immap_86xx.h was for 85xx. This patch fixes that and replaces the vague integer types with sized types of the correct endianness. The unused struct ccsr_pci is also deleted. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] add clrsetbits macrosTimur Tabi2007-09-141-0/+23
| | | | | | | | | | | | | This patch adds the clrsetbits_xxx() macros, which are used to set and clear multiple bits in a single read-modify-write operation. Specify the bits to clear in the 'clear' parameter and the bits to set in the 'set' parameter. These macros can also be used to set a multiple-bit bit pattern using a mask, by specifying the mask in the 'clear' parameter and the new bit pattern in the 'set' parameter. There are big-endian and little-endian versions for 8, 16, 32, and 64 bits. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] Add cpu feature for SPE handlingKumar Gala2007-09-145-28/+46
| | | | | | | | Make it so that SPE support can be determined at runtime. This is similiar to how we handle AltiVec. This allows us to have SPE support built in and work on processors with and without SPE. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* [POWERPC] Move PCI nodes to be sibilings with SOC nodesKumar Gala2007-09-1416-1285/+1323
| | | | | | | | | | | Updated the device trees to have the PCI nodes be at the same level as the SOC node. This is to make it so that the SOC nodes children address space is just on chip registers and not other bus memory as well. Also, for PCIe nodes added a P2P bridge to handle the virtual P2P bridge that exists in the PHB. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | 1. Update the way get_brgfreq() finds things in the device tree. It now uses names that are less namespace polluting. The old names are supported until all boards are converted. 2. "size" is changed from unsigned int to int, to match what of_get_property() expects.

| | | | | | | | | | | | Currently, the ps3 kernel fails to build without smp but with kexec, as ps3_kexec_cpu_down needs ps3_smp_cleanup_cpu, which isn't defined on UP kernels.

* [POWERPC] Add workaround for MPICs with broken register readsOlof Johansson2007-09-144-2/+27
| | | | | | | | | | | | | Some versions of PWRficient 1682M have an interrupt controller in which the first register in each pair for interrupt sources doesn't always read with the right polarity/sense values. To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution. Still, keep it under a config option to avoid wasting memory on other platforms. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback.
