[PATCH v2 4/4] arm64: imx8mp: imx8mp-phycore-som enable spi nor

From: Heiko Schocher
Date: Tue Mar 09 2021 - 00:33:53 EST


enable the mt25qu256aba spi nor on the imx8mp-phycore-som.

Signed-off-by: Heiko Schocher <hs@xxxxxxx>

---

Changes in v2:
- work in comments from Marco and Teresa
- rename node into "'som_flash: flash@0 { }"
- compatible is now first entry
- removed #size-cells and #address-cells
as no child node. If bootloader adds them bootloader
can add them too.
