From 83a18aefbdead8088f693917174ff01b8ae33650 Mon Sep 17 00:00:00 2001 From: Vincent Wiemann Date: Tue, 13 Aug 2019 01:26:45 +0200 Subject: [PATCH] ath79: add support for YunCore TFTP image generation YunCore QCA9k based devices released in 2019 require a custom TFTP image for U-Boot built-in recovery mode (triggered with reset button). Image has to be prepended with 'YUNCORE' keyword followed by U-Boot CLI commands which will be executed later. Images without the custom header will be ignored by U-Boot. To be able to support both the vendor firmware (QSDK) and OpenWrt flash layouts, used here commands change the 'bootcmd' before flashing image. This commit adds generic helper script for YunCore devices with 16 MB of flash and enables TFTP image generation for A770 model.
