| * | ARM: implement streaming DMA opsLucas Stach2015-03-062-0/+34
| | | | | | | | | | | | | | | Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | ARM: move DMA alloc functions to dma.hLucas Stach2015-03-0632-38/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This better separates the DMA from the MMU functionality. Also move all drivers that only depends on asm/mmu.h for the alloc functions over to the common header.

| * | dma: add streaming DMA opsLucas Stach2015-03-062-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | This will allow us to implement cache maintenance in a platform agnostic way. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | ARM: move virt<->phys translation to io.hLucas Stach2015-03-062-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | That's the place where Linux has them and other architectures would implement this. This will help in phasing out the direct usage of the ARM asm/mmu.h header. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | ARM: change dma_alloc/free_coherent to match other architecturesLucas Stach2015-03-0624-59/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM we define DMA_ADDRESS_BROKEN to mark them. In order to use them on other architectures with a different mapping they need proper fixing. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This allows to consolidate the prototype of this function across architectures. Also guard against calles that pass in NULL as the dma handle pointer. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The preloader import-script misses the sys_mgr_init_table variable.

To handle this gracefully, we extend the data abort exception handler to ignore the exception when configured to do so. This allows detecting inaccessible memory from the md command. It will show XX for unreadable bytes instead.
