TEE working now for Android, tested ok with COPS! * Updated according to review comments - Added ST-Ericsson copyright headers to all tee files. - Fixed problem with not using readl/writel when using ioremap. - Fixed problem with forgetting to do iounmap on special case. - Fixed incorrect usage when doing copy_to_user when writing to the device. - Added architecture dependent file for the tee service that calls the secure world. - Added support for more several inputs (sharedmemory buffers) for tee. - Added dummy macro to map MT_MEMORY device. - Fixed memory leak in secure world due to not closing a TEE session correctly from the kernel. - Now we only copies input buffer from user space for tee. - Documented structures in tee.h. - Moved SVP implementation into arch/arm/mach-ux500 folder. - Added new config flags for ux500 and SVP regarding TEE driver. - Update mach-ux500/Kconfig: - Enable TEE_UX500 by default when using target hardware. - Enabel TEE_SVP by default when building simulator. - Fix the cache sync problem: not request ROM code to clean cache - ioremap for ICN_BASE, remove static mapping in cpu-db8500.c. - Fix ioremap of ICN_BASE and do iounmap after use.
