From 780fc003ed2b70c49d3ddee99923594ccbc2adf6 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Fri, 12 Nov 2021 15:15:50 +0100 Subject: [PATCH] doc: rockchip: puma: update build and flash instructions Long gone is the time a custom TF-A was needed for Puma, upstream TF-A works just fine now. The flashing instructions are updated to match how newer rkdeveloptool and rkbin work. Finally, rkbin provides a way to flash SPI via USB OTG interface so let's document that.
