01abae4d04 Remove various unused interrupt related code
With d53ecad92f some unused interrupt related code was removed.
However all of these options are currently unused.  Rather than migrate
some of these options to Kconfig we just remove the code in question.

The only related code changes here are that in some cases we use
CONFIG_STACKSIZE in non-IRQ related context.  In these cases we rename
and move the value local to the code in question.

1f08aa1c9f net: gmac_rockchip: Add support for the RK3399 GMAC
The GMAC in the RK3399 is very similar to the RK3288 variant (i.e. it
is a Designware GMAC core and requires similar configuration as the
RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit).
The key difference is that the register offsets (within the GRF block)
and bit-offsets (within those registers) used to hold the configuration
differ between the various RK32/33 CPUs.

This change refactors the gmac_rockchip.c driver to use a function
table (selected via driver_data) to factor out these differences. Each
function's implementation then matches the underlying processor.

Some collateral changes are needed in the definitions describing the
bits and offsets in the GRF are needed to prefix each set of symbolic
constants with the SoC name to avoid name clashes... and in doing so,
the shifts for masks and constants have been moved into the header
files for readability (and to make it easier to stay below 80 chars).

09b3f948dc net: mvpp2: adapt rxq distribution to PPv2.2
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.

26a5278c9e net: mvpp2: handle register mapping and access for PPv2.2
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 common registers, and then one
  area per port.

- On PPv2.2, we have a first area for the common registers, and a
  second area for all the per-ports 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 the same
registers, but from different CPUs. Hence the introduction of cpu_base[]
in 'struct mvpp2', and the modification of the mvpp2_write() and
mvpp2_read() register accessors. For PPv2.1, the compatibility is
preserved by using an "address space" size of 0.

Changed by Stefan for U-Boot:
Since we don't support multiple CPUs in U-Boot, I've removed all the
code, macros and variables introduced in the Linux patch version for this.

b8c8e6ffac net: mvpp2: adapt mvpp2_defaults_set() to PPv2.2
This commit modifies the mvpp2_defaults_set() function to not do the
loopback and FIFO threshold initialization, which are not needed for
PPv2.2.

8f3e4c3800 net: mvpp2: adapt the mvpp2_rxq_*_pool_set functions to PPv2.2
The MVPP2_RXQ_CONFIG_REG register has a slightly different layout
between PPv2.1 and PPv2.2, so this commit adapts the functions modifying
this register to accommodate for both the PPv2.1 and PPv2.2 cases.

c8feeb2b93 net: mvpp2: adjust the allocation/free of BM pools for PPv2.2
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 physical and virtual address of each buffer
  requires reading the MVPP2_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 physical address to MVPP2_BM_PHY_VIRT_HIGH_RLS_REG. We no
  longer need to write the virtual address to MVPP2_BM_VIRT_RLS_REG.

f50a0118d1 net: mvpp2: introduce PPv2.2 HW descriptors and adapt accessors
This commit adds the definition of the PPv2.2 HW descriptors, adjusts
the mvpp2_tx_desc and mvpp2_rx_desc structures accordingly, and adapts
the accessors to work on both PPv2.1 and PPv2.2.
