Need some code adaptation in icE1usb firmware to
remove local usb_cdc_notif_serial_state struct
sine tt's included in no2usb cdc proto header now.

SB_I2C is apparently just a pain to use and buggy and such, so
use our custom one.

This core has been merged (and improved) upstream, so
update the submodule, remove local copy and make the required
tweaks.

We manually use global buffers for the signals that need to be
global, don't let nextpnr heuristic mess with things.

This just pulls in some small update in various files shared
by several repository. It's mostly comment and formatting, nothing
functionnal really.

Note that this is read-only. We drop all data from the host
because we can't have the host reconfigure the module ...

Not much change in e1, just a typo fix that just triggered a warning.
In usb the only relevant change is a fix in the stack code that caused
GET_INTERFACE to fail for interfaces without alt-settings

Without theses there are too many control-sets generated by yosys and
nextpnr can't find any valid placement.

By default build full bitstream, but from env or cli, allow to only
enable RX/TX units in channel 0 to speedup dev / testing.

The hard IP kind of sucks ... but we don't need i2c much (or at
all really) and using the hard IP is nearly free (LC-wise).

We have a bunch of Multiply Add units that are un-used, we can
make use of the "accumulate" part to implement the few wide
counters we have to win some LCs.

Theses syntax error are ignored by yosys but trying synopsys, it is more
strict, so fix them. Right thing to do anyway ...

Current version has second E1 channel disabled to allow the
build to works. Works is in progress to optimize the gateware and
the fpga toolchain to allow full featured build.

The documentation always had the rRX tick in the LSB which
is consistent with having the RX units before TX.
They can be read as 16 bit value anyway so there isn't any
performance impact.

This is the project specific to the e1-tracer board that was
initially based on the iCEpick with a couple dev boards attached
but eventually consolidated to a proper board, which still retaining
100% electrical compatibility (and thus same gateware and firmware)

This is the project specific to the PMOD based early prototype.
It was used either with the icebreaker or the icebreaker-bitsy
board as host. Set BOARD variable appropriately during build.
