crypto: caam - OP-TEE firmware support caam driver needs to be aware of OP-TEE f/w presence, since some things are done differently: 1. there is no access to controller's register page (note however that some registers are aliased in job rings' register pages) 2 Due to this, MCFGR[PS] cannot be read and driver assumes MCFGR[PS] = b'0 - engine using 32-bit address pointers. This is in sync with the fact that: -all i.MX SoCs currently use MCFGR[PS] = b'0 -only i.MX OP-TEE use cases don't allow access to controller register page Signed-off-by: Horia GeantA <horia.geanta@nxp.com> Signed-off-by: Meenakshi Aggarwal <meenakshi.aggarwal@nxp.com> Reviewed-by: Gaurav Jain <gaurav.jain@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: caam - Move debugfs fops into standalone file Currently the debugfs fops are defined in caam/intern.h. This causes problems because it creates identical static functions and variables in multiple files. It also creates warnings when those files don't use the fops. This patch moves them into a standalone file, debugfs.c. It also removes unnecessary uses of ifdefs on CONFIG_DEBUG_FS. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> [Moved most of debugfs-related operations into debugfs.c.] Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
