2019-07-23vboot: relocate call to vboot_save_recovery_reason_vbnvJoel Kitching
Relocate call to vboot_save_recovery_reason_vbnv and rename vb2_clear_recovery_reason_vbnv for consistency.

2019-07-03vboot: Use CONFIG_VBOOT_MIGRATE_WORKING_DATA on all platformsJulius Werner
When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on some Arm platforms the original working data buffer was in SRAM, which stays accessbile for the whole runtime of the system. There is no reason to migrate it into CBMEM on those platforms because ramstage and the payload could continue to access it in SRAM. Now that we've had a couple of months of experience with this option, we found that most of our Arm platforms have some issue that requires migrating anyway, because BL31 often claims SRAM for itself and makes it inaccessible to the payload. On the remaining platforms, accessing SRAM from the payload is possible but still an issue, because libpayload doesn't have enough memory layout information to set up proper page tables for it, so we're accessing it uncached and at risk of alignment errors. Rather than having to figure out how to map the right SRAM range for every platform in the payload, let's just get rid of the option. memcpy()ing 12KB isn't worth this much hassle.

2019-06-27vboot: remove vboot_handoff stepJoel Kitching
Depthcharge no longer reads this data structure, and uses the vboot workbuf in vboot_working_data instead. Since vboot2 downstream migration is not yet completed, the vboot2 -> vboot1 migration code is still required, but has been relocated to depthcharge.

2019-05-10vboot: Turn vboot_logic_executed() into a static inlineJulius Werner
This patch moves vboot_logic_executed() (and its dependencies) into a header and turns it into a static inline function. The function is used to guard larger amounts of code in several places, so this should allow us to save some more space through compile-time elimination (and also makes it easier to avoid undefined reference issues in some cases).

2019-05-10vboot: Make vboot_logic_executed() a bit more preciseJulius Werner
This patch adds another check to vboot_logic_executed() to make sure we only do a runtime check for verstage_should_load() if CONFIG_VBOOT_RETURN_FROM_VERSTAGE is enabled. That's the only case where the stage that's loading the verstage can execute after verification has run (because the verstage will return to it when it's done). In the other case, the stage that loads verstage really just loads it and will never do anything again after hand-off, so it's guaranteed to always execute before verification. This change may allow extra dead-code elimination in some cases.

2019-03-15vboot: rename symbols for better consistencyJoel Kitching
Symbols prefixed with vb2_ should be reserved for internal vboot library use. Anything outside of that may choose some other prefix. Here, we choose vboot_ instead. Also, add some documentation to security/vboot/misc.h, which provides headers for a number of different C files.

2019-03-14vboot: copy data structures to CBMEM for downstream useJoel Kitching
For platforms that do not employ VBOOT_STARTS_IN_ROMSTAGE, vboot verification occurs before CBMEM is brought online. In order to make vboot data structures available downstream, copy vb2_working_data from CAR/SRAM into CBMEM when CBMEM comes online.
