2024-04-08arm64: dts: microchip: sparx5_pcb135: drop duplicated NOR flashKrzysztof Kozlowski1-9/+0
Since beginning the DTS extended the SPI0 in two places adding two SPI muxes, each with same SPI NOR flash. Both used exactly the same chip-selects, so this was clearly buggy code. Then in commit d0f482bb06f9 ("arm64: dts: sparx5: Add the Sparx5 switch node") one SPI mux was removed, while keeping the SPI NOR flash node. This still leaves duplicated SPI nodes under same chip select 0, reported by dtc W=1 warnings: sparx5_pcb135_board.dtsi:92.10-96.4: Warning (unique_unit_address_if_enabled): /axi@600000000/spi@600104000/flash@0: duplicate unit-address (also used in node /axi@600000000/spi@600104000/spi@0) Steen Hegelund confirmed that in fact there is a SPI mux, thus remove the duplicated node without the mux.

2023-05-17arm64: dts: microchip: sparx5: do not use PSCI on reference boardsRobert Marko2-1/+13
PSCI is not implemented on SparX-5 at all, there is no ATF and U-boot that is shipped does not implement it as well. I have tried flashing the latest BSP 2022.12 U-boot which did not work. After contacting Microchip, they confirmed that there is no ATF for the SoC nor PSCI implementation which is unfortunate in 2023. So, disable PSCI as otherwise kernel crashes as soon as it tries probing PSCI with, and the crash is only visible if earlycon is used. Since PSCI is not implemented, switch core bringup to use spin-tables which are implemented in the vendor U-boot and actually work. Tested on PCB134 with eMMC (VSC5640EV).
