2014-11-24MIPS: Octeon: Delete potentially dangerous feature checksAaro Koskinen1-43/+0
We should not need to read fuses during normal operation, also the current code has issues with that (not safe for concurrent access). Since there are no in-kernel users for these, just delete them. Drivers should not need such OCTEON_HAS_FEATURE mechanism in any case, instead the information should be passed via device tree.

2009-09-17MIPS: Octeon: Check all CCAs in cvmx_write_csr.David Daney1-1/+1
The current code only checks CCA of 0 when deciding if a dummy read is needed. Since the kernel can (and does) use other CCAs we need to mask out the CCA bits from the address. Since the address constant now fits in 16 bits, there is an added benefit that smaller code is generated.

2009-01-11MIPS: Add Cavium OCTEON processor support files to ↵David Daney1-0/+505
arch/mips/cavium-octeon/executive and asm/octeon. These files are used to coordinate resource sharing between all of the programs running on the OCTEON SOC. The OCTEON processor has many CPU cores (current parts have up to 16, but more are possible). It also has a variety of on-chip hardware blocks for things like network acceleration, encryption and RAID. One typical configuration is to run Linux on several of the CPU cores, and other dedicated applications on the other cores. Resource allocation between the various programs running on the system (Linux kernel and other dedicated applications) needs to be coordinated. The code we use to do this we call the 'executive'. All of this resource allocation and sharing code is gathered together in the executive directory. Included in the patch set are the following files: cvmx-bootmem.c and cvmx-sysinfo.c -- Coordinate memory allocation. All memory used by the Linux kernel is obtained here at boot time. cvmx-l2c.c -- Coordinates operations on the shared level 2 cache. octeon-model.c -- Probes chip capabilities and version. The corresponding headers are in asm/octeon.
