information. So, removing the QEMU specific hacks from the
driver.

This change is to reduce the size of the static bbt table size
from 8KB to 4KB because so far we have not identified the
flash part that has more than 16K blocks and also it will
reduce the bsp size.
Driver warns if the device has more number of blocks than the
defined value so that this can be incremented in future and if
there is a part available.

As per the csurom, Bbt signature is always stored in oob area.
So, to sync with csurom, removing the NO_OOB(Bbt signature stores
in page area) functionality.

Controller supports only 8 bit mode. So, no need to configure
this value as this is the only option supported.

The current timeout value is not enough for erase operation on slower
devices. so increasing the timeout value and also added usleep for
timeout routine to have a precise timeout.

Removed the configuration of DMA Buffer Boundary register in WriteSpareBytes API
as the driver uses oob size as pkt size and thus configuring DMA Buffer
Boundary Register has no effect.

Since the check for the block to have reached the end block was at the end of the loop,
thus assert call triggering could happen if the block crosses the max block limit,
making the driver to hang. Thus to fix the triggering of assert call,
the check for the block to have reached the max block is being done at the start of
the loop in XNandPsu_CalculateLength function.
The u32 typecasting for the variable OffsetVar has been removed and the data type for
the variable TempLen has been changed to u64 as for higher block numbers the value for
these variables will require u64 datatype otherwise corrupted value will get stored
which will lead to wrong calculation of block.

Ensure that the dma buffer boundary interrupt is disabled as driver
is using the contiguous buffer for the whole page size and enabling
this interrupt would cause failures if the buffer boundary is
configured for other values (not the page size)
