From 715634e6d1443eacdcb84b04d1028c1564b08dbf Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Fri, 12 Jul 2024 11:36:47 +0200 Subject: [PATCH] base-files: upgrade: nand: use "cmd" argument for extracting command MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit NAND code uses either "cat" or "zcat" for getting firmware image content. Code was full of duplicated ${gz}cat calls. Use "cmd" variable that is determined by a caller and passed to lower level functions. This avoids code duplication and allows adding support for more formats.
