TX and RX descriptors are 16 bytes. This causes problems with the cache
maintenance on CPUs where the cache-line size exceeds the size of these
descriptors. What will happen is that when the driver receives a packet
it will be immediately requeued for the hardware to reuse. The CPU will
therefore need to flush the cache-line containing the descriptor, which
will cause all other descriptors in the same cache-line to be flushed
along with it. If one of those descriptors had been written to by the
device those changes (and the associated packet) will be lost.
To work around this, we make use of non-cached memory if available. If
descriptors are mapped uncached there's no need to manually flush them
or invalidate them.

This change is necessary as an additional 2 MB is
allocated as reserved memory for TZ_APPS exposed
in qseecom driver and we must notify the same
boundary as FDT_HIGH to uboot.
Without this change, the board gets stuck in uboot
with starting kernel message during boot up.

During kernel bootup, dcache is enabled to reduce boot time.
When CONFIG_SYS_DCACHE_OFF macro is defined, dcache will not
be enabled.

Do generic flash structure initialization, for the devices
not listed in the SPI NOR flash lookup table, so that
we can access the flash even before the support is added.
Block size and density are obtained from smem.

This patch adds the support on nand driver to work
when dcache is on.
flush_dcache_range will do both clean and invalidate.
To avoid any data loss when an un-aligned buffer used
in RX path, before giving buffer to bam and after bam
updates the data in buffer, buffer will be flushed.
