Subject: [PATCH v2 06/21] ARM: rpi: switch to ARM_USE_COMPRESSED_DTB
Date: Thu,  9 Jun 2022 07:59:07 +0200	[thread overview]
Message-ID: <20220609055922.667016-7-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220609055922.667016-1-a.fatoum@pengutronix.de>

We'll add a generic image containing multiple DTs in a follow-up commit,
which would benefit from compressing the DTs. For uniformity, compress
the existing DTs as well to save some kilobytes there.
