Subject: [PATCH 5/5] ARM: AT91: migrate sama5d3-xplained to DT
Date: Wed, 22 Sep 2021 08:50:01 +0200
Message-ID: <20210922065000.20970-6-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210922065000.20970-1-a.fatoum@pengutronix.de>

We have one other DT-enabled SAMA5D3 board already:
microchip-ksz8477-evb, which is basically a sama5d3 xplained in
different form factor and with a switch. Mimic what we do there to get
rid of the sama5d3 board code.

Unlike the microchip-ksz9477-evb, the barebox support for this board
includes NAND, which is not yet up to date with respect to DT:

  - SMC for NAND configuration has no DT driver. Instead the board
    driver create this device
  - We don't support the newer NAND DT bindings (EBI). The device trees
    fix this up, so barebox sees the old bindings with the upstream
    partition layout. In future, this could be fixed.
