We have conducted some testing and completed the = third version of the patch. 1) Blurb We have added some descriptions in Blurb to explain the current status, tes= ting situation, and limitations of the project. 2) Milk-V Pioneer board Our team does not have a Milk V Pioneer board. But we asked the help of oth= er cooperative teams to test it, the test results indicate that EVB and Pio= neer boards are not fully compatible. The SD card driver cannot correctly r= ecognize all partitions and start the Linux operating system.

Thanks for your comments. We have conducted some testin= g and completed the third version of the patch.

1) <= span style=3D"white-space-collapse: preserve;">Blurb
We have ad= ded some descriptions in Blurb to explain the current status, testing situa= tion, and limitations of the project.

2) Milk-V Pioneer board
Our team does not have a Milk V = Pioneer board. But we asked the help of other cooperative teams to test it,= the test results indicate that EVB and Pioneer boards are not fully compat= ible. The SD card driver cannot correctly recognize all partitions and star= t the Linux operating system. Sorry, our team has no plans to add support f= or Pioneer board.

3) Layout
Based on your comments, we have modified the code layout of the port an= d moved most of the
Platform/Sophgo/SG2042Pkg/
to Silicon/Sophgo/SG2042Pkg/
The specific changes can be found in the sub= mitted third version of the patch or in the link of the public git tree pro= vided in Blurb.

4) Clang toolchain support
I‘m trying to use the CLA= NGDWARF toolchain (clang version 18.0.0) to build ports. It is able to buil= d successfully but the compiled binary was not fully work. It's strange tha= t the SD card driver got stuck in a loop while reading a data block. Adding= multiple lines of printed output to the read data block function of the SD= card can run normally and successfully start the Linux OS.

Thanks,
Yuqing Cai
