G, Manjunath Kondaiah d3c9be2f42 OMAP: DMA: Introduce errata handling feature ... Implement errata handling to use flags instead of cpu_is_* and cpu_class_* in the code. The errata flags are initialized at init time and during runtime we are using the errata variable (via the IS_DMA_ERRATA macro) to execute the required errata workaround. Reused errata handling patch from: Peter Ujfalusi <peter.ujfalusi@nokia.com> https://patchwork.kernel.org/patch/231191/ Changes to above patch: 1. Changes are done for converting all the existing errata work arounds to use this feature. 2. Detailed description for each errata is added. 3. Fixed bug in SET_DMA_ERRATA macro 4. Bit shifting in macro definitions are replaced with BIT() macro Signed-off-by: G, Manjunath Kondaiah <manjugk@ti.com> Tested-by: Kevin Hilman <khilman@deeprootsystems.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>		2010-12-20 18:38:29 -08:00
