RISCV port for JDK11u

[yangfei at iscas.ac.cn]

Hi,

I would still suggest we sync with jdk11u-dev with which the riscv-port-jdk11u [1] repo is seeded. 
Give the fact that there are only two planned merges from jdk11u-dev to jdk11u for each release, we won't be able to sync with latest jdk11u-dev in a timely manner if we base the work on top of jdk11u. 
This will be a problem especially when there are port-specific changes in upstream jdk11u-dev. I don't think it's a good idea to wait for the two planned merges from jdk11u-dev to jdk11u. 

And it should not be that complex if you want to do a stable released from this riscv-port-jdk11u repo. 
Simply git reset to some 'special' commit like [2] for version 11.0.20. This commit is also there in repos like jdk11u-dev and riscv-port-jdk11u. 
I see there will always be such a commit for each jdk11u update release version.

Subject: Re: RISCV port for JDK11u

Hello.  if the port will be living in separate repo for some time, may I suggest to base it on top of jdk11u? not jdk11u-dev. so a stable builds of risv-ojdk11 could be created without much hassle.  
  
  regards, Vladimir

That's right.

Exactly so. We should accommodate a RISCV port in the updates repo, but
whether it will ever be integrated into the long-term-stable 11u is
another matter.
