I'm not asking for in-depth analysis, just an overview.
What's wrong with the default config?
Why is the signal quality bad and what makes it bad?
What did the old magic numbers do?
How will the configuration differ if I applied your patch?
It is a little different between simulation and real chip. We have no idea
about which configuration is better before tape-out. We set default settings
according to simulation, but need to tune these parameters after getting the
real chip.
Those old magic numbers are proper in simulation environment, but not good in
real ASIC chip.
If the new patch won't be applied, we may failed to access SD card in those
platforms equipped with rts5249 module.
