System call table generation script must be run to generate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script.
This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by arch/microblaze/Makefile and the generated files against the removed files will be identical.
The generated uapi header file will be included in uapi/asm/unistd.h and generated system call table support file will be included by kernel/syscall_table.S file.

and here too.
Thanks for your comment. checkpatch script didn't warn this one:( Hopefully, I can fix this one in the next version.
I would appreciate if you can perform the boot test on the actual platform and share the result with me.
I see one issue there. Run make mrproper make ARCH=microblaze headers_install INSTALL_HDR_PATH=/tmp/1/
And then
make mrproper make archheaders V=1 make ARCH=microblaze headers_install INSTALL_HDR_PATH=/tmp/2/
And compare output. What I see is that in the first part asm/unistd_32.h pointing to asm-generic/unistd_32.h
But when archheaders is run before there is expected content.
That means there is incorrect/missing dependency in Makefiles.
Time to time I am able to see compilation warnings but I didn't find exact steps to replicate this but it also looks like on missing dependency somewhere.

When build is fine system is booting fine (v4.19-rc6 + your patches).
Thanks for your support. I'll work on the same which shared above. I'll update you asap with the fix.
I'm bit busy this week, working on parisc and ia64 support. Hopefully I can update you next week.
no worries.
