Some spi nand flash uses single byte read id(9FH) command,
for those devices the sequence is
byte1 byte2 byte3 byte4
9FH MID DID DID
some other spi nand flashes uses two byte read id(9F 00H) command
for those devices the sequence is
byte1 byte2 byte3 byte4
9FH A7-A0 MID DID
The first byte is the actual command and the second byte is a dummy byte.
For devices which uses new sequence, we need to pass
appropriate read id command with dummy byte.

This change will clear the divider value while doing deinit of
SD devices. In-order to clear the divider value we have to write
into register GCC_SDCC1_MISC.
Writing 0x0 to this register will clear the divider value which is
set, while doing initialization got SD devices.
Without this change, while kernel bootup we can see the below error.
error:
[3.529917] mmc0: Skipping voltage switch
[4.131741] mmc0: error -110 whilst initialising SD card.

This change is a workaround for Micron eMMC card. As per the card
extended CSD register value, the minimum size of a write protect
region is 0x8000 blocks (16MB). So the user should give start address
and size to align with 0x8000. But this eMMC part actually does
protect 32MB of memory.
We changing the minimum write protect region size from 0x8000 to
0x10000 for Micron eMMC card.

The Device will accept the requested number of data blocks, terminate
the transaction and return to transfer state. Stop command is not
required at the end of this type of multiple blocks write unless
terminated with an error. This change will send the
STOP_TRANIMISSION command if the command failed.

During serial init after relocation, if TX FIFO is
not empty, clock init on-the-fly causes baudrate
flucutation resulting in TX data corruption and
outputs as garbage data on the console.
This patch fixes this by waiting until TX FIFO
gets flushed before serial initialization starts.

This patch checks for the errors during the fifo write itself
like in qca_pio_read function. Previously, error was checked
only after the total xfer_size is written to the fifo and
errors during the fifo write operation were ignored.

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.
