From 6ed39520a70e76dd9b3f374d62a60de986f051c0 Mon Sep 17 00:00:00 2001 From: Jonas Karlman Date: Fri, 28 Jul 2023 11:38:40 +0000 Subject: doc: rockchip: Update SPI flashing instruction Update documentation on how to write a bootable u-boot-rockchip-spi.bin image into SPI flash. This removes the reference to a hardcoded and now obsolete 0x60000 payload offset. Also remove an obsolete reference to pad_cat.
