From 5e90144aec50f1a394f62ef4691c7c51f5517cbe Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sat, 6 Jun 2015 17:05:31 +0000 Subject: bcm53xx: sysupgrade: extract TRX partitions directly from vendor image MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extracting full TRX out of vendor format is not needed as otrx supports passing TRX offset. This saves some RAM during sysupgrade.
