Adds configuration switch CFG_TA_FTPM_RPMB_STORAGE that, when enable, makes fTPM OP-TEE TA to explicitly use the eMMC RPMB secure storage of OP-TEE instead of OP-TEE private storage which depends on OP-TEE configuration. The configuration switch is default disabled for compatibility reasons. Signed-off-by: Etienne Carriere <[email protected]>

There was a problem hiding this comment.
Maybe the configuration should get the storage ID instead of a a boolean value that selects between TEE_STORAGE_PRIVATE and TEE_STORAGE_PRIVATE_RPMB. Here:
CFG_FTPM_TA_TEE_STORAGE_ID ?= TEE_STORAGE_PRIVATE
