@ChengJin01 @keithc-ca fyi

[ChengJin01]

There is no code or setting changes specific to RISC-V on my side.

[keithc-ca]

I think there are two problems here.

1. builds fail when DDR is not enabled
2. it appears there's a conflict between parallel tasks when DDR is enabled

[ChengJin01]

DDR should be disabled via cross-compilation on the local/host system for RISC-V (only enabled if directly compiled on RISC-V with a cross-build as a boot/build JDK).

[pshipton]

The fixes are merged.
