[GitHub] [incubator-nuttx] masayuki2009 opened a new pull request #988: arch: k210: Fix cpu1 hangup during boot with qemu

masayuki2009 opened a new pull request #988:
URL: https://github.com/apache/incubator-nuttx/pull/988


   ## Summary
   
   - I noticed that sometimes cpu1 hangs during boot with qemu.
   - In boot up process, cpu1 needs to wait for g_serial_ok is set to true which means that cpu0 finished serial driver initialization.
   - However previous logic initializes g_serial_ok to false by each cpu which caused cpu1 hang up.
   - This PR simply removes such an incorrect logic.
   
   ## Impact
   
   - This PR affects k210 only.
   
   ## Testing
   
   - I tested this PR for both k210 and qemu.
