From b42297ba8136c10bbd9b2b2b5f76ad836e456935 Mon Sep 17 00:00:00 2001 From: Alper Nebi Yasak Date: Sat, 29 Jan 2022 18:27:56 +0300 Subject: [PATCH] rockchip: Set default LNX_KRNL_IMG_TEXT_OFFSET_BASE to SYS_TEXT_BASE U-Boot can be chainloaded from vendor firmware on ARM64 chromebooks from a GPT partition (roughly the same as in doc/chromium/chainload.rst), but an appropriate image header must be built-in to the U-Boot binary by enabling LINUX_KERNEL_IMAGE_HEADER. This header has a field for an image load offset from 2MiB alignment which must also be customized through LNX_KRNL_IMG_TEXT_OFFSET_BASE. Set it equal to SYS_TEXT_BASE by default for Rockchip boards, which happens to make this offset zero and works fine on chromebook_kevin both for chainloading and bare-metal use.
