support for sh2(SH7615)

[kalyantej k. <kal...@ya...>]

  Hi everyone,
   
  I am trying to port UClinux for SH7615 processor.The kernel was able to boot properly .
   
  Before exceuting shell , I tried to execute a simple hello world application,
   
  It also works properly ,but when I try to fork a new process the system crashes.
   
  I found some code in entry.S which never get executed,
   
  In macros SAVE_ALL and RESTORE_ALL,there is a conditional check before proceeding to 
   
  Kernel/user mode , where the current->tss.sr value is checked for.
   
  But when is this value of current->tss.sr is changed !
   
  May be I hope that there is no separate stack for user mode and kernel mode,due to Which 
   
  the fork gets failed .
   
  Is this a known problem in linux-2.0.x of uClinux-distribution .
   
  Please let me know if there is support for SH2 .
   
  Please help me , thanks in advance,
  Regards,
  Kalyan
