software/liblitesdcard: Fix condition in sdcard_init
...
Instead of retrying `sdcard_app_send_op_cond` until it returns an error,
retry until it completes successfully and the command response has the
busy bit set.

interconnect/axi/axi_full: Switch to our own AXI Interconnect (Shared & Crossbar).
...
We were not able to simulate verilog_axi interconnect/crossbar correctly since to what
seems to be a simulation mismatch. The code also seems to requires fixing some synthesis
issues with Yosys. When tested with Vivado, the SoC was also miss-behaving (not booting
correctly).
The simulation mismatch issue is logged here: https://github.com/enjoy-digital/litex_verilog_axi_test/issues/1
Since we already had our own AXI-Lite interconnect, creating our AXI interconnect can be
largely based on it with only minor modifications, so switch to it. This also allow simplification
in the interconnect selection/instance.

integration/soc: Add initial AXI-full support.
...
Main bus can now be switched to AXI-full with --bus-standard=axi.
The interconnect will be AXI-Full (Using Alex Forenchich's verilog_axi
Interconnect and Crossbar) but ROM/SRAM will still be in AXI-Lite (Will
be switched to AXI-full in the future).
This gives a first working version that can be used for further improvements.
Note that the interconnect can also be selected by --bus-interconnect=shared or
crossbar.

It's only boot tested in sim and build tested in Vivado now, and it

The ISR code is based on Rocket one.
