Re: [U-Boot] [PATCH v2 2/2] imx:mx6sxsabresd add qspi support
Hi Peng Fan,
Before reviewing these two patches, I'm requesting some sort work from
your side like
Can you update/fix the driver drivers/spi/fsl_qspi.c without using
flash opcodes.
Using flash opcode's with in the (q)spi driver is not recommended
please think on that
direction.

Yeah, many OPCODE_XX are used in this driver.
There is a LUT table containing 16 entries in the QSPI Controller.
The Look-up-table or LUT consists of a number of pre-programmed sequences. Each
sequence is basically a sequence of instruction-operand pairs which when
executed
sequentially generates a valid serial flash transaction. Each sequence can have
a
maximum of 8 instruction-operand pairs.
The instruction holds the flash opcode that should be pre-programmed, and the
qspi_set_lut in drivers/spi/fsl_qspi.c does this work.
It is not easy to program the lut dynamically in the driver without using the
flash opcodes.
So I wonder whether CMD_xxx in drivers/mtd/spi/sf_internal.h can be used or
not. Or,
can QSPI_CMD_xxx be used but not OPCODE_xx? Actually if QSPI_CMD_xx can be
used, the value
QSPI_CMD_xx is the same with OPCODE_xx, just different macro names.
Regards,
Peng.
