Subject: [PATCH v2 13/16] ARM: dts: microchip-ksz9477-evb: add dummy first stage device tree
Date: Tue, 19 Feb 2019 18:21:47 +0100 [thread overview]
Message-ID: <20190219172150.11901-14-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20190219172150.11901-1-a.fatoum@pengutronix.de>
The existing device tree is too big for the 64K byte constrained
first stage.
Because of the size limitation it might be better to only use
the device tree for the second stage. This increases user-friendliness
by leaving space for PBL_CONSOLE.
For now provide a slightly smaller smaller *-boot-bin.dts device tree
for first stage, which can be further stripped in future commits.
