Sujet : [PATCH 3/3] ARM: socfpga: xload: compress image with xz
Date : Wed, 04 Mar 2026 14:51:25 +0100
De : David Picard <david.picard@clermont.in2p3.fr>
Pour : David Picard <david.picard@clermont.in2p3.fr>
Compress the image of the first stage of Barebox with xz because it
features a good compression ratio.
Rationale: on some devices, the image has to fit in a ROM as small
as 64KiB.
