(I'm working on it and have result to nearly the same patch)
I've test your code against current U-Boot
and I've found that the input stell no working

after some debug I've that qemu call twice the function sh_serial_can_receive1
which return false twice. Just after U-Boot enable the receive (writing RE and
TE in SCR) but qemu will not re-call sh_serial_can_receive1.

As test If we force to always return 1 to sh_serial_can_receive1 the input
work

I've start to search how to notify qemu that U-Boot active/desativate the
receive

Best Regards,
