The algorithm works unconditionally. If bitval is one, the first line is
a no op and the second line sets the bit at offset position. Vice versa,

After applying the following changes I could verify functionality by
mounting a filesystem on the cfdisk and reading/writing files in it.
The set_irq_type() function must be wrong, as there is no set_type()
function defined for the rb532 IRQ chip. But as the used IRQ actually is
being triggered by a GPIO, setting it's interrupt level should be the
right alternative. Also to clear a GPIO triggered IRQ, the source has to
be cleared. This is being done at the end of rb532_pata_irq_handler.

* rename the offset definition to avoid abiguity with the standard ATA
IO address
* read and write four bytes at once like the original driver does
* use writesl() and readsl() which implicitly iterate over the data
This patch assumes buflen to be a multiple of four, which is true for
ATA devices. ATAPI support is not known, though unlikely, as the
original driver always transfers 512 Bytes at once.

Per definition, this function should return the number of bytes
consumed. Also take care of the unlikely case when buflen is not a
multiple of four; while transferring, the division cuts the remaining
bytes, so alter the return value accordingly.

The new value is the one used in the external patch before and allows at
least a standard MTU of 1500 to be handled correctly. Impact of this
change gets visible when bigger packets are to be received, issuing:

and bigger payload sized led to 100% packet loss.

Originally this must have been a rewrite error when introducing
'chain_index'. But the original driver did not use the previous chain
item everywhere: when altering the address tx_chain_tail points to, it
should move forward, not backwards.
Also this is not an "index" but rather the penultimate element in the
chain, so rename it accordingly.

As the assigned value is being overwritten shortly after, it can be
dropped and so the whole variable definition moved to the start of the
function.

After the last loop iteration, i has the value RC32434_NUM_RDS and
therefore leads to an index overflow when used afterwards to address the
last element. This is yet another another bug introduced when rewriting
parts of the driver for upstream preparation, as the original driver
used 'RC32434_NUM_RDS - 1' instead.

This is copy and paste from the original driver. As skb_reserve() is
also called within korina_alloc_ring() when initially allocating the
receive descriptors, the same should be done when allocating new space
after passing an skb to upper layers.
