I don't know the protocol for revisiting broken patches that have already been integrated, but the patched offered by NXP for their ls1046a RDB is wrong.
original patch: http://lists.denx.de/pipermail/u-boot/2016-September/265974.html The main error is this patch defines CONFIG_SPI_FLASH_BAR which enables use of a bank address register to access flash addresses beyond 16M. +/* QSPI device */ +#ifdef CONFIG_FSL_QSPI +#define CONFIG_SPI_FLASH_SPANSION +#define FSL_QSPI_FLASH_SIZE (1 << 26) +#define FSL_QSPI_FLASH_NUM 2 +#define CONFIG_SPI_FLASH_BAR +#endif However the Cypress S25FS512S part used on the LS1046A RDB does not implement any bank address related commands. See section 1.2.2.9 of http://www.cypress.com/file/216376/download This configuration error means that any attempt to access beyond the first 16MB of flash will silently wrap around to the beginning of the flash. This is in addition to the bugs in flash erase on this platform previously noted - http://lists.denx.de/pipermail/u-boot/2016-December/276032.html _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
