This reverts commit 40892b0c08fbc8029921e91511dd3f91fc956f90. The feature of returning progress for libflashrom users was introduced in original commit, however later a bug was found and reported as https://ticket.coreboot.org/issues/390. Reverting in a release branch to unblock release candidate, since it is unknown how much time needed to fix the bug. Meanwhile the feature remains in a master branch and will be fixed under ticket 390. TEST=scenarios below run successfully 1) flashrom -h does not show --progress 2) flashrom -p dummy:emulate=W25Q128FV -r /tmp/dump.bin 3) flashrom -p dummy:emulate=W25Q128FV -v /tmp/dump.bin 4) flashrom -p dummy:emulate=W25Q128FV -E 5) head -c 16777216 </dev/urandom >/tmp/image.bin flashrom -p dummy:image=/tmp/image.bin,emulate=W25Q128FV \ -w /tmp/dump.bin Change-Id: Id3d7ffcaf266a60a44eb453fd09b7c63c05349c2 Signed-off-by: Edward O'Callaghan <quasisec@google.com> Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/69283 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Singer <felixsinger@posteo.net>
