spi: cadence-quadspi: Use STIG mode for all ops with small payload
OSPI controller supports all types of op variants in STIG mode,
only limitation being that the data payload should be less than
8 bytes when not using memory banks.
STIG mode is more stable for operations that send small data
payload and is more efficient than using DMA for few bytes of
memory accesses. It overcomes the limitation of minimum 4 bytes
read from flash into RAM seen in DAC mode.
Use STIG mode for all read and write operations that require
data input/output of less than 8 bytes from the flash, and thereby
support all four phases, cmd/address/dummy/data, through OSPI STIG.
Also, remove the reorder address chunk in apb_command_write since we now
setup ADDR BIT field that does the same job in a cleaner way.
spi: cadence-quadspi: Fix check condition for DTR ops
buswidth and dtr fields in spi_mem_op are only valid when the
corresponding spi_mem_op phase has a non-zero length. For example,
SPI NAND core doesn't set buswidth when using SPI_MEM_OP_NO_ADDR
phase.
Fix the dtr checks in set_protocol() to ignore empty spi_mem_op
phases, as checking for dtr field in empty phase will result in
false negatives.
This patch adds fixups for s25fs512s to address the following issues
from reading SFDP:
- Non-uniform sectors by factory default. The setting needs to be
checked and assign erase hook as needed.
- Page size is wrongly advertised in SFDP.
- READ_1_1_2 (3Bh/3Ch), READ_1_1_4 (6Bh/6Ch), and PP_1_1_4 (32h/34h)
are not supported.
- Bank Address Register (BAR) is not supported.
In addition, volatile version of Quad Enable is used for safety.
Based on patch by Takahiro Kuwano with s25fs_s_post_bfpt_fixup() updated
to use 4-byte address commands instead of extended address mode and the
page_size is fixed to 256
For future use, manufacturer code should be moved out from framework
code as same as in Linux.
