net: mvpp2: add initial support for PPv2.2

The goal of this patch series is to add basic support for PPv2.2 in
the existing mvpp2 driver. mvpp2 currently supported the PPv2.1
version of the IP, used in the 32 bits Marvell Armada 375 SoC. PPv2.2
is an evolution of this IP block, used in the 64 bits Marvell Armada
7K/8K SoCs.

In order to ease the review, the introduction of PPv2.2 support has
been made into multiple small commits, with the final commit adding
the compatible string that makes the PPv2.2 support actually
usable. The series remain fully bisectable.

People interested in testing the code will find the full series (plus
a few Device Tree patches) at:

  https://github.com/MISL-EBU-System-SW/mainline-public/tree/4.11/mvpp2.2-support-v3

I'd like to thank Stefan Chulski and Marcin Wojtas, who helped me a
lot in the development of this patch series, by reviewing the patches,
and giving lots of useful hints to debug the driver on PPv2.2. Thanks
as well to Russell King for reviewing previous iterations of this
series, and providing suggestions and fixes.

Changes between v2 and v3:

 - Rebased on v4.11-rc1.

 - Add patch "net: mvpp2: fix DMA address calculation in
   mvpp2_txq_inc_put()", to properly take into account the "packet
   offset" field of the TX descriptors. Without this, we were getting
   DMA_API_DEBUG warnings that we are unmapping DMA mappings with a
   non-mapped DMA address.

 - In patch "net: mvpp2: add and use accessors for TX/RX descriptors",
   add a function named mvpp2_txdesc_offset_get(), which is needed for
   the DMA address calculation fix.

 - In patch "net: mvpp2: add and use accessors for TX/RX descriptors",
   fix the calculation of tx_desc physical address and packet offset
   in mvpp2_tx_frag_process(). The offset was assigned into the buffer
   physical address, and the physical address to the packet offset,
   which meant the fragment process was completely broken.

 - In patch "net: mvpp2: adjust the allocation/free of BM pools for
   PPv2.2" fix how MVPP22_BM_ADDR_HIGH_VIRT_RLS_MASK is used. This
   mask is already shifted. So the value should be shifted before
   being masked and not the opposite.

 - Add a new patch "net: mvpp2: set dma mask and coherent dma mask on
   PPv2.2", to set the DMA mask and DMA coherent mask. By setting the
   DMA mask to 40 bits we avoid using bounce buffers when network
   packets are above the 4 GB limit. The coherent mask remains set to
   32 bits, because the BM pools must all have the same high 32 bits
   in their addresses.

 - Use "dma" instead of "phys" where appropriate, as suggested by
   Russell King.

 - Use the "cookie" field of the RX descriptor to store the physical
   address instead of the virtual address, and then use phys_to_virt()
   to get the virtual address. This allows to work around the limit
   that the "cookie" field only has 40 bits, which is not sufficient
   to store a virtual address on 64 bits platforms. This was suggested
   by Russell King.

   As part of this change, also got rid of all the compile time
   conditionals on CONFIG_ARCH_DMA_ADDR_T_64BIT, to get better
   compile-time coverage.

 - In patch "net: mvpp2: handle misc PPv2.1/PPv2.2 differences":

    * Instead of calling mvpp21_port_power_up(port) only on PPv2.1,
      remove this function, and call its relevant parts directly from
      ->probe(). Only mvpp2_port_fc_adv_enable() is PPv2.1
      specific. Reported by Russell King.

    * Add a mvpp22_port_mii_set() function that properly initializes
      SGMII support on PPv2.2. Code provided by Russell King.

 - In patch "net: mvpp2: handle register mapping and access for PPv2.2":

    * Adjust the code to match the change of the DT binding in terms
      of mapping the second register area on PPv2.2.

    * Rework the register accessors to remove the get_cpu()/put_cpu(),
      and instead use separate accessors for global registers
      vs. per-CPU registers.

 - Add a few new patches removing dead/unused/useless code:

   net: mvpp2: remove support for buffer header
   net: mvpp2: remove unused register definition MVPP2_TXQ_THRESH_REG
   net: mvpp2: remove mvpp2_txq_pend_desc_num_get() function

 - Fix a number of checkpatch warnings.

Changes between v1 and v2:

 - Made a separate series from the set of patches doing preparation
   changes/fixes to the mvpp2 driver.

 - Rebased on top of v4.10-rc1.

 - Update Kconfig text of the mvpp2 driver to mention the support for
   Armada 7K and 8K (PPv2.2).

On PPv2.2, the streaming mappings can be anywhere in the first 40 bits
of the physical address space. However, for the coherent mappings, we
still need them to be in the first 32 bits of the address space,
because all BM pools share a single register to store the high 32 bits
of the BM pool address, which means all BM pools must be allocated in
the same 4GB memory area.

In PPv2.1, we have a maximum of 8 RXQs per port, with a default of 4
RXQs per port, and we were assigning RXQs 0->3 to the first port, 4->7
to the second port, 8->11 to the third port, etc.

In PPv2.2, we have a maximum of 32 RXQs per port, and we must allocate
RXQs from the range of 32 RXQs available for each port. So port 0 must
use RXQs in the range 0->31, port 1 in the range 32->63, etc.

This commit adapts the mvpp2 to this difference between PPv2.1 and
PPv2.2:

 - The constant definition MVPP2_MAX_RXQ is replaced by a new field
   'max_port_rxqs' in 'struct mvpp2', which stores the maximum number of
   RXQs per port. This field is initialized during ->probe() depending
   on the IP version.

 - MVPP2_RXQ_TOTAL_NUM is removed, and instead we calculate the total
   number of RXQs by multiplying the number of ports by the maximum of
   RXQs per port. This was anyway used in only one place.

 - In mvpp2_port_probe(), the calculation of port->first_rxq is adjusted
   to cope with the different allocation strategy between PPv2.1 and
   PPv2.2. Due to this change, the 'next_first_rxq' argument of this
   function is no longer needed and is removed.

This commit adjusts the mvpp2 driver register mapping and access logic
to support PPv2.2, to handle a number of differences.

Due to how the registers are laid out in memory, the Device Tree binding
for the "reg" property is different:

 - On PPv2.1, we had a first area for the packet processor
   registers (common to all ports), and then one area per port.

 - On PPv2.2, we have a first area for the packet processor
   registers (common to all ports), and a second area for numerous other
   registers, including a large number of per-port registers

In addition, on PPv2.2, the area for the common registers is split into
so-called "address spaces" of 64 KB each. They allow to access per-CPU
registers, where each CPU has its own copy of some registers. A few
other registers, which have a single copy, also need to be accessed from
those per-CPU windows if they are related to a per-CPU register. For
example:

  - Writing to MVPP2_TXQ_NUM_REG selects a TX queue. This register is a
    per-CPU register, it must be accessed from the current CPU register
    window.

  - Then a write to MVPP2_TXQ_PENDING_REG, MVPP2_TXQ_DESC_ADDR_REG (and
    a few others) will affect the TX queue that was selected by the
    write to MVPP2_TXQ_NUM_REG. It must be accessed from the same CPU
    window as the write to the TXQ_NUM_REG.

Therefore, the ->base member of 'struct mvpp2' is replaced with a
->cpu_base[] array, each entry pointing to a mapping of the per-CPU
area. Since PPv2.1 doesn't have this concept of per-CPU windows, all
entries in ->cpu_base[] point to the same io-remapped area.

The existing mvpp2_read() and mvpp2_write() accessors use cpu_base[0],
they are used for registers for which the CPU window doesn't matter.

mvpp2_percpu_read() and mvpp2_percpu_write() are new accessors added to
access the registers for which the CPU window does matter, which is why
they take a "cpu" as argument.

The driver is then changed to use mvpp2_percpu_read() and
mvpp2_percpu_write() where it matters.

This commit adjusts the allocation and freeing of BM pools to support
PPv2.2. This involves:

 - Checking that the number of buffer pointers is a multiple of 16, as
   required by the hardware.

 - Adjusting the size of the DMA coherent area allocated for buffer
   pointers. Indeed, PPv2.2 needs space for 2 pointers of 64-bits per
   buffer, as opposed to 2 pointers of 32-bits per buffer in
   PPv2.1. The size in bytes is now stored in a new field of the
   mvpp2_bm_pool structure.

 - On PPv2.2, getting the DMA address and cookie (used for the physical
   address) of each buffer requires reading the
   MVPP22_BM_ADDR_HIGH_ALLOC to get the high order bits of those
   addresses. A new utility function mvpp2_bm_bufs_get_addrs() is
   introduced to handle this.

 - On PPv2.2, releasing a buffer requires writing the high order 32 bits
   of the DMA address and cookie to MVPP22_BM_PHY_VIRT_HIGH_RLS_REG.

The PPv2.2 IP has a different TX and RX descriptor layout compared to
PPv2.1. In order to prepare for the introduction of PPv2.2 support in
mvpp2, this commit adds accessors for the different fields of the TX
and RX descriptors, and changes the code to use them.

For now, the mvpp2_port argument passed to the accessors is not used,
but it will be used in follow-up to update the descriptor according to
the version of the IP being used.

Apart from the mechanical changes to use the newly introduced
accessors, a few other changes, needed to use the accessors, are made:

 - The mvpp2_txq_inc_put() function now takes a mvpp2_port as first
   argument, as it is needed to use the accessors.

 - Similarly, the mvpp2_bm_cookie_build() gains a mvpp2_port first
   argument, for the same reason.

 - In mvpp2_rx_error(), instead of accessing the RX descriptor in each
   case of the switch, we introduce a local variable to store the
   packet size.

 - In mvpp2_tx_frag_process() and mvpp2_tx() instead of accessing the
   packet size from the TX descriptor, we use the actual value
   available in the function, which is used to set the TX descriptor
   packet size a few lines before.

The RX descriptors of the PPv2 hardware allow to store several
information, amongst which:

 - the DMA address of the buffer in which the data has been received
 - a "cookie" field, left to the use of the driver, and not used by the
   hardware

In the current implementation, the "cookie" field is used to store the
virtual address of the buffer, so that in the receive completion path,
we can easily get the virtual address of the buffer that corresponds to
a completed RX descriptors.

On PPv2.1, used on 32-bit platforms, those two fields are 32-bit wide,
which is enough to store a DMA address in the first field, and a virtual
address in the second field.

On PPv2.2, used on 64-bit platforms, these two fields have been extended
to 40 bits. While 40 bits is enough to store a DMA address (as long as
the DMA mask is 40 bits or lower), it is not enough to store a virtual
address. Therefore, the "cookie" field can no longer be used to store
the virtual address of the buffer.

However, as Russell King pointed out, the RX buffers are always
allocated in the kernel linear mapping, and therefore using
phys_to_virt() on the physical address of the RX buffer is possible and
correct.

Therefore, this commit changes the driver to use the "cookie" field to
store the physical address instead of the virtual
address. phys_to_virt() is used in the receive completion path to
retrieve the virtual address from the physical address.

It is obviously important to realize that the DMA address and physical
address are two different things, which is why we store both in the RX
descriptors. While those addresses may be identical in some situations,
it remains two distinct concepts, and both addresses should be handled
separately.

The mvpp2_txq_pend_desc_num_get() function only selects a TX queue, and
reads the number of pending descriptors. It is used in only one place,
in mvpp2_txq_clean(), where the TX queue has already been selected by a
write to MVPP2_TXQ_NUM_REG.

Therefore, this function is useless, and the caller can simply read the
value of the MVPP2_TXQ_PENDING_REG register instead.

The "buffer header" functionality is a functionality used by the
hardware to split an incoming packets over multiple BM buffers if they
are not large enough. However, the mvpp2 driver guarantees that a pool

packets. Therefore, this functionality is completely unused, and the
code can be removed, and we should never get a descriptor with bit

Use of order-3 pages is problematic in some cases.

This patch might add three kinds of regression :

1) a CPU performance regression, but we will add later page
recycling and performance should be back.

2) TCP receiver could grow its receive window slightly slower,
   because skb->len/skb->truesize ratio will decrease.
   This is mostly ok, we prefer being conservative to not risk OOM,
   and eventually tune TCP better in the future.
   This is consistent with other drivers using 2048 per ethernet frame.

3) Because we allocate one page per RX slot, we consume more
