sf: Add memory mapped read support

2013-10-07T12:25:51+00:00

Qspi controller can have a memory mapped port which can be used for
data read. Added support to enable memory mapped port read.

This patch enables the following:
- It enables exchange of memory map address between mtd and qspi
through the introduction of "memory_map" flag.
- Add support to communicate to the driver that memory mapped
 transfer is to be started through introduction of new flags like
"SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END".

This will enable the spi controller to do memory mapped configurations
if required.

spi: Add support for preamble bytes

2013-06-02T18:34:40+00:00

A SPI slave may take time to react to a request. For SPI flash devices
this time is defined as one bit time, or a whole byte for 'fast read'
mode.

If the SPI slave is another CPU, then the time it takes to react may
vary. It is convenient to allow the slave device to tag the start of
the actual reply so that the host can determine when this 'preamble'
finishes and the actual message starts.

Add a preamble flag to the available SPI flags. If supported by the
driver then it will ignore any received bytes before the preamble
on each transaction. This ensures that reliable communication with
the slave is possible.

spi: Add parameter for maximum write size

2013-03-19T15:45:36+00:00

Some SPI controllers (e.g. Intel ICH) have a limit on the number of SPI
bytes that can be written at a time. Add this as a parameter so that
clients of the SPI interface can respect this value.

spi: Add function to allocate a new SPI slave

2013-03-19T15:45:36+00:00

At present it is difficult to extend the SPI structure since all
drivers allocate it themselves, and few of them zero all fields. Add
a new function spi_alloc_slave() which can be used by SPI drivers
to perform this allocation, and thus ensure that all drivers can
better cope with SPI structure changes.
