| | | | | | | | | | | | | | | | | | This CL in case of unorderly TPM reset that doesn't also reset GSC preserves RAM-backed values of orderly nv indices. BUG=b:201101365 TEST=1) create an orderly counter 2) increment it 3) trigger EC reset 4) verify that the counter value was preserved Cq-Depend: chromium:3417937 Change-Id: I799183ad06584055d025c2acf5f83ff2ded32d39 Signed-off-by: Andrey Pronin <apronin@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/3418122 Reviewed-by: Vadim Bendebury <vbendeb@chromium.org> Commit-Queue: Mary Ruthven <mruthven@chromium.org>

| | | | | | | | | | | | | | | | | This change adds a new random salt generated and persisted during first use of U2F to DRBG initialization. Also marks the key handle as 'additional input' rather than including in initial inialization value.
