* These pins are overlaid on mprj_io space. They have the function
* below when the management processor is in reset, or in the default
* configuration. They are assigned to uses in the user space by the
* configuration program running off of the SPI flash. Note that even
* when the user has taken control of these pins, they can be restored
* to the original use by setting the resetb pin low. The SPI pins and
* UART pins can be connected directly to an FTDI chip as long as the
* FTDI chip sets these lines to high impedence (input function) at
* all times except when holding the chip in reset.

Corrected the last testbenches, added a new testbench for the spi_master since the original one was folded into the sysctrl testbench, but that testbench no longer uses the SPI master. Moved the SPI master from being an overlay of the housekeeping SPI to occupying GPIO pins 32 to 35. Made GPIO 35 a bidirectional pin like 36 and 37 so that the output enable from the SPI master can be used.

Corrections to the padframe to make sure that all pad digital inputs that are permanently tied low or high come from either the local "TIE" pad connections (if they are in the 3.3V domain) or from a constant one wire in the 1.8V domain that is generated in the gpio_control_block module and exported to the chip_io (or chip_io_alt) module.

(1) Corrected an error from a recent commit where the reset was fixed by moving from after the managment protect to before it, but an inversion of the signal was missed, leading to an incorrect wb_rst_i passed to housekeeping. (2) Revised the method to load the serial GPIO data chain from a 2-pin, I2C-like method to a more straightforward 3-pin method with separate reset, clock, and load pins. The load pin propagates through the chaing like the other two. Added a bit-bang signal for the load signal as well. (3) Added an implied buffer after the data output of the GPIO control block to ensure that the data arrives at the next control block after the clock, to prevent hold violations.

/* the three-pin interfaces */
Several more LVS corrections, including fixing a label in chip_io that got removed from its net by a chang in the LEF view of an I/O pad, and a lack of declaration of an array to attach to pwr_ctrl_out in the verilog, which is valid verilog but netgen can't know the bus size without the no-connect net being declared. The remaining issue has to do with separation of ground domains in the mgmt_protect block.

Added the rest of the testbenches: mprj_bitbang, perf, pll, qspi, and storage. Not all of these pass simulation checks. Added back the bit-bang control of the GPIO programming. Added back the read-only interface between the housekeeping module and the SRAM 2nd port. Revised the memory map text document to reflect the addition of the SRAM ports.

Implemented a system for setting the GPIO power-on defaults through via programming. The values for each of the GPIOs at power-up are defined in the "user_defines.v" file. For the verilog, they are applied as parameters. For the layout, they will need to be separately defined cells for each of the GPIOs, or at least for each set of unique default values.

(2) Revised the method to load the serial GPIO data chain from a 2-pin, I2C-like method to a more straightforward 3-pin method with separate reset, clock, and load pins. The load pin propagates through the chaing like the other two. Added a bit-bang signal for the load signal as well. (3) Added an implied buffer after the data output of the GPIO control block to ensure that the data arrives at the next control block after the clock, to prevent hold violations.

Corrected the clock signal into the housekeeping module, which was incorrectly assigned to the clock on the user side of the managment protect block, causing it to be undefined when the user area power supply is down. The "hkspi_power" testbench which tests using the housekeeping SPI while the user area power is grounded now works correctly.

Several more LVS corrections, including fixing a label in chip_io that got removed from its net by a chang in the LEF view of an I/O pad, and a lack of declaration of an array to attach to pwr_ctrl_out in the verilog, which is valid verilog but netgen can't know the bus size without the no-connect net being declared. The remaining issue has to do with separation of ground domains in the mgmt_protect block.

A handful of changes/corrections: (1) Housekeeping signal "user_clock" (input for monitoring) changed from being connected directly to the user project (where it shouldn't be) to the same signal on the input side of the management protect block (where it should be). This is functionally the same. Checked for any other signals connected directly from the user project to any block other than mgmt_protect, didn't find any (good). Modified the gate-level netlists and top-level layouts for caravel and caravan with the corresponding change. This was the only change affecting layout. Also: Revised the "pll" testbench. This is still ongoing work. Also: Fixed the way the pins on I/O pads are declared in chip_io.v, mprj_io.v, and pads.v, so that it isn't so bizarre. Most of this change is functionally agnostic (just a change in the way the ifdefs work), but did fix an incorrect ifdef that causes the whole user power domain to be broken.

// Each control block sits next to an I/O pad in the user area.
// It gets input through a serial chain from the previous control
// block and passes it to the next control block. Due to the nature
// of the shift register, bits are presented in reverse, as the first
// bit in ends up as the last bit of the last I/O pad control block.
// There are two types of block; the first two and the last two
// are configured to be full bidirectional under control of the
// management Soc (JTAG and SDO for the first two; flash_io2 and
// flash_io3 for the last two). The rest are configured to be default
// (input). Note that the first two and last two are the ones closest
// to the management SoC on either side, which minimizes the wire length
// of the extra signals those pads need.

Corrected the last testbenches, added a new testbench for the spi_master since the original one was folded into the sysctrl testbench, but that testbench no longer uses the SPI master. Moved the SPI master from being an overlay of the housekeeping SPI to occupying GPIO pins 32 to 35. Made GPIO 35 a bidirectional pin like 36 and 37 so that the output enable from the SPI master can be used.

/* Last three GPIOs (spi_sdo, flash_io2, and flash_io3) */
Implemented a system for setting the GPIO power-on defaults through via programming. The values for each of the GPIOs at power-up are defined in the "user_defines.v" file. For the verilog, they are applied as parameters. For the layout, they will need to be separately defined cells for each of the GPIOs, or at least for each set of unique default values.

// Management Soc-facing signals
Made updates to correct LVS errors in caravan. Found one major error in the RTL verilog for both caravel and caravan. Hand-edited the RTL and GL netlists to correct this; still need to correct the layouts. The error causes the user1 side clock, load, and reset buffers to drive the user2 side as well as the user1 side, making a huge mess of the routing. Will route this by hand.

/* Spare logic for metal mask fixes */
Effectively reverted the change to add spare logic blocks near each (#157) * Effectively reverted the change to add spare logic blocks near each of the GPIO control blocks by changing the definition of NUM_SPARE_BLOCKS to 4 (the original number of spare logic blocks) for both caravel and caravan top level RTL verilog modules. * Apply automatic changes to Manifest and README.rst Co-authored-by: RTimothyEdwards <RTimothyEdwards@users.noreply.github.com>

Revised the spare logic block to make sure that all inputs are reachable from pins on the boundary once it's synthesized.

Seeding with documentation of pinout and verilog RTL (mostly unchanged from original except to remove blocks that are not supposed to be in this repository like the processor core and the storage).
