mtd: rawnand: stm32_fmc2: avoid to lock the CPU bus
...
commit 4114b17af41272e14939b000ce8f3ed7ba937e3c upstream.
We are currently using nand_soft_waitrdy to poll the status of the NAND
flash. FMC2 enables the wait feature bit (this feature is mandatory for
the sequencer mode). By enabling this feature, we can't poll the status
of the NAND flash, the read status command is stucked in FMC2 pipeline
until R/B# signal is high, and locks the CPU bus.
To avoid to lock the CPU bus, we poll FMC2 ISR register. This register
reports the status of the R/B# signal.
