Heinrich Schuchardt	99bfab8b58	efi_loader: identify PK, KEK, db, dbx correctly ... To determine if a varible is on the of the authentication variables PK, KEK, db, dbx we have to check both the name and the GUID. Provide a function converting the variable-name/guid pair to an enum and use it consistently. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>	2020-07-16 12:37:02 +02:00
Heinrich Schuchardt	012c56ac76	efi_loader: restructure code for TEE variables ... When using secure boot functions needed both for file and TEE based UEFI variables have to be moved to the common code module efi_var_common.c.

Heinrich Schuchardt	01df8cf336	efi_loader: separate UEFI variable API from implemementation ... Separate the remaining UEFI variable API functions GetNextVariableName and QueryVariableInfo() from internal functions implementing them.

Heinrich Schuchardt	f2d2b3a11c	efi_loader: prepare for read only OP-TEE variables ... We currently have two implementations of UEFI variables: * variables provided via an OP-TEE module * variables stored in the U-Boot environment Read only variables are up to now only implemented in the U-Boot environment implementation. Provide a common interface for both implementations that allows handling read-only variables. As variable access is limited to very few source files put variable related definitions into new include efi_variable.h instead of efi_loader.
