Subject: [PATCH 0/5] kexec_file_load() for arm
Date: Mon, 1 Jun 2020 16:27:49 +0200 [thread overview]
Message-ID: <20200601142754.26139-1-l.stelmach@samsung.com> (raw)
In-Reply-To: CGME20200601142806eucas1p2680c5625411e7a695d8469760a926520@eucas1p2.samsung.com
The following series of patches provides implementation of the
kexec_file_load() system call form the arm architecture. zImage and uImage
(legacy format) files are supported. Like on arm64, there is no
possibility of loading a new DTB and the currently loaded is reused.
Łukasz Stelmach (5):
arm: decompressor: set malloc pool size for the decompressor
arm: add image header definitions
arm: decompressor: define a new zImage tag
arm: Add kexec_image_info
arm: kexec_file: load zImage or uImage, initrd and dtb
