This adds an interface for configuring Qualcomm's "secure SMMU" and adds support for booting the modem Hexagon on MSM8996. Two new debugfs entries are added in the remoteproc core to introspect the list of memory carveouts and the loaded resource table. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaD26iAAoJEAsfOT8Nma3FUp0QAL/WZhL8QsvVFbAlv/Aa6NKm z8blXscD0GKdQWDWGaGPtpbnpOWOYhJs9WxstiB2q9ooSa9brIdjG5ukr4DTgtRs 12If5tfkVFIjlBhAdYYK+biNSQtZE+37jb7aJ+j4N3Po3O72pxekcLMLhAdvY6yk zHnhDZ8N7KBxAa0eOg7PJz7AGRF6BHhPxkqgJm0FzBj4HLQ/lwrv6iYJRrZgw6CT OhIHgPwCSHmt2fTO2QDLOWJtbVMSFhunHbuYlzPwvhMAGCT87VmXCIkW8iVhcD24 uJMrFbQoBoWVMB68JgGUKd7SSs8pV7DMrGfJll1kBEQfMLynn8Omre7WDAfwjUEn ACasSDWdWEPABJoIRVkGhS+2BnfCehdvDC7QxFFPAf8oc49O3t6DyXcCQdcVkzzE f1r/G2JKsoNQxjklFJewU5r0EjWgvV/78Dmpi7tuUtjgMSyEqkYORmInbbFIqZrU 9bHCqrmlxuRFSklxoG2u7F2SVYgMVlqM4rmj8QqR85SeIfyZtcCx5i5yAj8dZsI1 JVjucOCROHFqs/3SYFKlo6x4XHIchJD4p64QOXPCVhw7R1NXTPRTFBCQ75PKdiD1 d7kcGhdaz2cMeN1WRhIQ00lh/uiDNd4Ez7sDuU8MnWiEcIs1/ZP1LCHZTNttoljH rWZp4XlrhT+Vx91zV5u5 =lnNj -----END PGP SIGNATURE----- Merge tag 'rproc-v4.15' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This adds an interface for configuring Qualcomm's "secure SMMU" and adds support for booting the modem Hexagon on MSM8996.
