Cover letter [U-Boot] [PATCH v4 0/5] qspi: qspi support for mx6sxsabresd
Quoted 10 lines · Jagan Teki
Quoted 8 lines · Peng Fan

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.

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
