* crypto: aesni-intel - RFC4106 AES-GCM Driver Using Intel New InstructionsTadeusz Struk2010-11-132-2/+1708
| | | | | | | | | | | | | | | | | This patch adds an optimized RFC4106 AES-GCM implementation for 64-bit kernels. It supports 128-bit AES key size. This leverages the crypto AEAD interface type to facilitate a combined AES & GCM operation to be implemented in assembly code. The assembly code leverages Intel(R) AES New Instructions and the PCLMULQDQ instruction.

| | | | * dmaengine: Add Freescale i.MX SDMA supportSascha Hauer2010-10-053-6/+86
| | | |/ | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the Freescale i.MX SDMA engine. The SDMA engine is a scatter/gather DMA engine which is implemented as a seperate coprocessor. SDMA needs its own firmware which is requested using the standard request_firmware mechanism. The firmware has different entry points for each peripheral type, so drivers have to pass the peripheral type to the DMA engine which in turn picks the correct firmware entry point from a table contained in the firmware image itself. The original Freescale code also supports support for transfering data to the internal SRAM which needs different entry points to the firmware. Support for this is currently not implemented. Also, support for the ASRC (asymmetric sample rate converter) is skipped. I took a very simple approach to implement dmaengine support. Only a single descriptor is statically assigned to a each channel. This means that transfers can't be queued up but only a single transfer is in progress. This simplifies implementation a lot and is sufficient for the usual device/memory transfers.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the generic DMAEngine API has support for scatterlist to scatterlist copying, the device_prep_slave_sg() portion of the DMA_SLAVE API is no longer necessary and has been removed. However, the device_control() portion of the DMA_SLAVE API is still useful to control device specific parameters, such as externally controlled DMA transfers and maximum burst length. A special dma_ctrl_cmd has been added to enable externally controlled DMA transfers. This is currently specific to the Freescale DMA controller, but can easily be made generic when another user is found. Signed-off-by: Ira W.

However, rather than being done through a pair of instructions, it's driven by writing to a pair of memory-mapped CPU control registers. One set of these registers (AARU/ADRU/ASRU) is available for use by userspace, but for userspace to access them a PTE must be set up to cover the region. This is done by dedicating the first vmalloc region page to this purpose, setting the permissions on its PTE such that userspace can access the page. glibc is hardcoded to expect the registers to be there. The way atomic ops are done through these registers is straightforward: (1) Write the address of the word you wish to access into AARU. This causes the CPU to go and fetch that word and load it into ADRU. The status bits are also cleared in ASRU. (2) The current data value is read from the ADRU register and modified. (3) To alter the data in RAM, the revised data is written back to the ADRU register, which causes the CPU to attempt to write it back. (4) The ASRU.RW flag (ASRU read watch), ASRU.LW flag (bus lock watch), ASRU.IW (interrupt watch) and the ASRU.BW (bus error watch) flags then must be checked to confirm that the operation wasn't aborted. If any of the watches have been set to true, the operation was aborted. Signed-off-by: Mark Salter <msalter@redhat.com> Signed-off-by: David Howells <dhowells@redhat.com>

| * | MN10300: SMP: Differentiate local cache flushingAkira Takeuchi2010-10-274-112/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Differentiate local cache flushing from global cache flushing so that they can be done differently on SMP systems. Rename the cache functions from: mn10300_[id]cache_*() to: mn10300_[id]_localcache_*() and on a UP system, assign the global labels to the local labels.

| * | MN10300: Cacheflush functions should take unsigned long addressesAkira Takeuchi2010-10-272-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | The functions that perform cache flushing should take addresses of unsigned long type, not unsigned int.

| * | MN10300: AM34: The current cacheflush routines operate by controlling tag regsDavid Howells2010-10-274-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current cache flush and invalidate routines operate by controlling the cache tag registers. Rename the files and add config items to select them. This makes it easier to support the use of other cache flush methods instead, such as the use of AM34's area purge registers, if available.

| * | MN10300: Reorder asm/cacheflush.h to put primitives firstDavid Howells2010-10-271-44/+44
| | | | | | | | | | | | | | | | | | | | | | | | Reorder asm/cacheflush.h to put arch primitives first, before the main functions so that the main functions can be inline asm rather than #defines when non-trivial. Signed-off-by: David Howells <dhowells@redhat.com>
| * | MN10300: Provide a MN10300_CACHE_ENABLED config optionDavid Howells2010-10-276-10/+13
| | | | | | | | | | | | | | | | | | | | | Provide a MN10300_CACHE_ENABLED config option as inverted logic of MN10300_CACHE_DISABLED to make things simpler. Signed-off-by: David Howells <dhowells@redhat.com>

| | | | | | | | | | | | | | | | | | Split the cache bits out of arch/mn10300/Kconfig as they're quite complex. Signed-off-by: David Howells <dhowells@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the monitor trap function and the set_jtag_stub function as they're not really necessary.
