From 543f24dffcf1a85faf95228c0d0ba2dee097939f Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Thu, 18 Jan 2024 14:55:55 +0100 Subject: [PATCH] rockchip: rk3399: simplify logic for getting SPL boot medium DT node In preparation of moving spl_perform_fixups to spl-boot-order.c, let's simplify the logic around mapping the BOOT_DEVICE_x enum index to a DT node by using an instantiated array of chars instead of creating a new data structure on the fly. This will make it easier to factor out the code handling the SPL boot medium detection by having spl_decode_boot_device common to all SoCs.
