- Add Gemmini-baremetal examples for spike and verilator evaluation.
- Add more gemmini conv2d operation examples (like conv-2d-nhwc-fhwc).
…evaluation. 2. Add more gemmini conv2d operation examples.

Have not seen the E2E example.
Is the remaining E2E C++ error ('_start_main_argv') related to using riscv64-unknown-elf-gcc (expecting riscv64-unknown-elf-g++) for end-to-end?

Yes, E2E example still block points at compiling with riscv64-unknown-elf-g++.
I will try to fix it and follow up with a full version commit.

The [ on each line should align with the [ on the previous line.
This looks better.

This pr other examples also have this problem, you need to look at it again, thank you.

PK_CC or ELF_CC Is there a better name?
| ### Hardware Evaluation | ||
| Step 1. Execute `make <workload>-run-baremetal` in this folder to generate the baremetal test case. | ||
|
|
||
| Step 2. Copy the generated test case `<workload>-baremetal` to the gemmini workload storage path in the chipyard folder (`chipyard/generators/software/gemmini-rocc-tests/build/`) |

I think maybe copy is not necessary? I'm not sure anymore.
