Subject: [PATCH 2/2] scripts/dtc: Update to upstream version v1.4.7
Date: Tue, 19 Feb 2019 12:37:00 +0100 [thread overview]
Message-ID: <20190219113700.10172-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20190219113700.10172-1-a.fatoum@pengutronix.de>
This commit was generated by running ./scripts/dtc/update-dtc-source.sh
from the otherwise empty directory.
Besides updating to the most recent dtc release (so that /omit-if-no-ref/
becomes available), it reinstates the dtc-lexer.l and
dtc-parser.y files which were erroneously deleted in place of their
pregenerated _shipped.c versions.
Also removed are fdtputc.c and fdtdump.c, which aren't built or used
anywhere.
This adds the following commits from upstream:
