Florent Kermarrec 2384d6fbd4 cores/hyperbus: Add initial HyperRAM Register access over CSRs.
Will be used to get HyperRAM characteristics and also to configure latency and enable varialble latency.

Untested yet.

Andrew Dennison 5d1fa7b6ca cores/spi_mmap: fix data if bus width > length
Details:
* 32bit bus write to 8 and 16bit MSB first slot resulted
  in shifted data on mosi.
* 32bit read from 8 and 16bit LSB first slot resulted
  with shifted data in fifo.
Fixes 2 tests - all current tests now pass.

Richard Tucker 6170c90459 soc/cores/spi_mmap: adjust CSR mapping to better suit drivers
Currently the TX_RX_ENGINE CSR register lives below the
slot registers which are dynamic in length (based on how
many slots (chip selects) are configured in the gateware).

Move the TX_RX_ENGINE CSR to above the SLOT configuration
registers so TX_RX_ENGINE never moves.

This makes for an easier and cleaner driver.

Andrew Dennison 0cb101da25 build/efinix/platform: fix get_pin_name()
get_pin_name did not include the resource index, so additional core
instances were generated with identical pin names. See below for
examples.

Also only adds slice index for slices with more than one io for cleaner
naming.

("i2c", 0,
    Subsignal("scl", Pins(...)),
    Subsignal("sda", Pins(...)),
),
("i2c", 1,
    Subsignal("scl", Pins(...)),
    Subsignal("sda", Pins(...)),
),

Before:
    output wire          i2c0_oe,
    input  wire          i2c0_scl,
    input  wire          i2c0_sda,
    input  wire          i2c1_scl,
    input  wire          i2c1_sda,
    input  wire          i2c_scl0_IN,
    input  wire          i2c_scl0_IN_1,
    input  wire          i2c_scl0_IN_2,
    output wire          i2c_scl0_OE,
    output wire          i2c_scl0_OE_1,
    output wire          i2c_scl0_OE_2,
    input  wire          i2c_sda0_IN,
    input  wire          i2c_sda0_IN_1,
    input  wire          i2c_sda0_IN_2,
    output wire          i2c_sda0_OE,
    output wire          i2c_sda0_OE_1,
    output wire          i2c_sda0_OE_2,

After:
    output wire          i2c0_oe,
    input  wire          i2c0_scl,
    input  wire          i2c0_scl_IN,
