Kyle Kearney 96cfc7393d Disable attempted 4-byte addressing for some boards 
4-byte addressing has been seen to cause failures on NORDIC
boards and with Macronix memories. Suppress the attempt to enable it
on that hardware (via vendor quirks and a target check) until either
the failure cause can be fixed or a more robust suppression mechanism
is implemented.

Kyle Kearney 2526b9fc00 QSPIF: Handle fast mode enable via vendor quirks 
Use a vendor id check to only perform this enable on devices which define the
 second configuration register where the fast mode enable bit lives.
Change _enable_fast_mode to use the standard status register reading and writing functions

Kyle Kearney 02dbf68e17 QSPIF: Handle parts with extra config registers 
Default to 2 status registers, but update this value if necessary
 during vendor quirk handling for parts (currently only Macronix)
 which have one status register and two control registers. For the
 purposes of QSPIFBlockDevice, these are all considered status
 (or at least "status-like") registers because they are all written
 via the Write Status Register instruction.
Set the custom RDCR instruction for Macronix during quirk handling.
Update reading and writing of status registers to handle a variable
 number of status registers.

Kyle Kearney eb5494e7a9 QSPIF: Centralize handling of vendor quirks 
Introduce a separate function for handling alterations to device interaction
which are not covered by the SFDP tables and therefore require checking against
the vendor id.

Kyle Kearney 26314d96c5 Don't clear quad enable when clearing block protection 
QSPIFBlockDevice::_clear_block_protection() has logic to retain the
WIP and WEL bits in status register 1, but it failed to account for
the situation where the QE bit is also in status register 1.
In _sfdp_set_quad_enabled, note the status register and bit therein
for the quad enable, so that _clear_block_protection can retain it.

Kyle Kearney d2ef56859c QSPIF: Add back enable_fast_mode 
This function writes a "config" register to ensure that the flash part
is in high performance mode, not low-power mode. This is required at
by at least MX25R6435F in order to operate at frequencies > 33MHz
(for reference, DISCO_L475VG_IOT01A runs the QSPI interface at 80 MHz).
The config register that this writes does not appear to be covered by
the SFDP spec (JESD216D.01) so this remains the status quo of
unconditional execution, as has been done on master since #8352.

Matthew Macovsky b1916fc498 Introduce qspi_inst_t type for QSPI instructions 
Encourage the usage of consistent types (there are currently
 a mix of `int` and `unsigned int` used for qspi instructions)
QSPI commands are limited to 8 bits, to this is a typdef to char

Kyle Kearney 52cb2c2cfc Avoid stale mutex in QSPIFBlockDevice::read 
Update to follow the same `goto exit_point` pattern that is used
by the rest of the functions to avoid leaving the mutex locked
when errors are detected and require the function to abort.

Kyle Kearney 3f20b80859 Reuse existing error for _qspi_configure_format 
Use QSPIF_BD_ERROR_DEVICE_ERROR instead of introducing a new error code.
Add tr_error calls whenever _qspi_configure_format fails to aid in debugging.

Kyle Kearney 726a73c048 Report errors returned by _qspi_configure_format 
The function returns a qspi_status_t but most usages in QSPIFBlockDevice
assume that it always succeeds.

Matthew Macovsky 6bba46e48f Differentiate alt and dummy cycles in QSPIF 
Propagate separate alt cycle and dummy cycle counts from QSPIFBlockDevice
down to the qspi driver, so that drivers which handle the two separately have
enough information to do so.
 2019-09-30 16:17:49 -07:00
Matthew Macovsky baf375f8cb Allow for arbitrary QSPI alt sizes 
The QSPI spec allows alt to be any size that is a multiple of the
number of data lines. For example, Micron's N25Q128A uses only a
single alt cycle for all read modes (1, 2, or 4 bits depending on
how many data lines are in use).

offirko b79c64ec53 Favor QSPI Bus mode 1-4-4 over QPI 
QPI may have slightly better performance, but it is not supported by all targets.
It requires register setup between each Read and Program/Erase commands,
which might damage the overall performance eventually.
