Hi All,
I have a system with multiple CPU cores. I have multiple threads
assigned to particular CPU. Among these threads the main thread calls
sched_yield() if it has nothing to do, I am hoping that doing so will
give chance to other threads to run. But the strange behavior of
sched_yield() is ,
() is , even if there are ready-to-runs tasks on this CPU
waiting for their turn, the task which calls sched_yield() is always
running ( get scheduled) and not giving chance to any other task to
run. It is consuming 100% of CPU. Is sched_yield() is broken on 2.6
Kernel?

Some SPI controllers can't write nor->page_size bytes in a single
step because their TX FIFO is too small.
Allow nor->write() to return a size that is smaller than the requested
write size to gracefully handle this case.

Add flags for Octal I/O data transfer
Required for the SPI controller which can do data transfer (TX/RX)
on 8 data lines e.g. NXP FlexSPI controller.
SPI_TX_OCTAL: transmit with 8 wires
SPI_RX_OCTAL: receive with 8 wires

Some SPI controllers can't write nor->page_size bytes in a single
step because their TX FIFO is too small.
Allow nor->write() to return a size that is smaller than the requested
write size to gracefully handle this case.

all we have to do here is

spi_mem_exec_op() operation.
