[U-Boot] [PATCH v5] arm: dts: Stratix10: Add QSPI node
Merge qspi dts node from Linux. Commit 0cb140d07fc75fb (arm64: dts: stratix10: Add QSPI support for Stratix10)
Add -u-boot.dtsi files for non Linux dts properties and update properties for Uboot. - add u-boot,dm-pre-reloc - add alias for spi0 - change compatible for flash - support quad read and quad write - change maximum frequency to 100MHz
Tested on Stratix 10 SoC devkit. SOCFPGA_STRATIX10 # sf probe 0:0 SF: Detected mt25qu02g with page size 256 Bytes, erase size 64 KiB, total 256 MiB
