This patch set is to support qspi for mx6sxsabresd board.
To mx6sxsabresd Revb board, 32M flash is used, but in header file, CONFIG_SPI_FLASH_BAR is not defined, and we still use SZ_16M. The LUT initialization qspi_set_lut function uses 32BIT addr, however CONFIG_SPI_FLASH_BAR and 24BIT addr should be used to access bigger than 16MB size flash, and BRRD/BRWR should also be supported. Future patches will fix this.
Please do remember your self, for next patches. of-course I have added this note on "[U-Boot,v4,5/5] imx:mx6sxsabresd add qspi support" commit body.
Thanks. Actually I am doing the work.
Since flash opcodes are not recommended to use in driver level, use QSPI_CMD_xx to replace OPCODE_xx. It is qspi controller's feature to program LUT with QSPI_CMD_xx which same value with OPCODE_xx.
Since Revb board's qspi flash support 4K erase, 4K erase is added in driver.
Peng Fan (5): QuadSPI: use QSPI_CMD_xx instead of flash opcodes QuadSPI: use correct amba_base arm:mx6sx add QSPI support imx:qspi add 4K erase support imx:mx6sxsabresd add qspi support
