From 6dd18a6568a7272c86f12aec6f657b13fa52a226 Mon Sep 17 00:00:00 2001 From: Vaishnav Achath Date: Fri, 3 Jun 2022 11:32:15 +0530 Subject: common: spl: spl_spi: add support for dynamic override of sf bus Currently the SPI flash to load from is defined through the compile time config CONFIG_SF_DEFAULT_BUS and CONFIG_SF_DEFAULT_CS, this prevents the loading of binaries from different SPI flash using the same build.E.g. supporting QSPI flash boot and OSPI flash boot on J721E platform is not possible due to this limitation. This commit adds lookup functions spl_spi_boot_bus() and spl_spi_boot_cs for identifying the flash device based on the selected boot device, when not overridden the lookup functions are weakly defined in common/spl/spl_spi.c.
