    op-build Remove DD1.0 Support / Add DD2.x fixes 09-19-2017

commit ee9bec06bd104a8f4d7edf210547690af0f2073d
Author: Bill Hoffa <wghoffa@us.ibm.com>

    op-build Remove DD1.0 Support / Add DD2.x fixes 09-19-2017
    
      - Due to space contraints, critical workarounds for DD1.0
        have been dropped. DO NOT USE ON DD1.x systems. An HB
        patch is included to detect a Nimbus DD1.0 System and
        halt the IPL with an error message to the console.
    
      Changes included for hostboot-binaries:
      - Move HCODE to hw091517b.910
    
      Changes included for hostboot (as a patch):
      3fc1354 - Dean Sanner - 2017-09-19 - Remove support for P9N (Nimbus) DD1.0

Ends up removing support to boot DD1 for hostboot, so we should be safe with enabling STRICT_RWX as if you're grabbing bits from upstream op-build and trying them on DD1 you're already getting to keep both pieces.

linux: Update P9 defconfig for 4.13
efe5b09 
 - We lost the lockup detector when the Kconfig options were renamed
 - Enable the hung task detector
 - Turn on STRICT_KERNEL_RWX
 - We lost IRQ_DOMAIN_DEBUG when DEBUG_FS was disabled. Leave it off
 - CONFIG_SMP now defaults to true, so it is not in the defconfig

Note that STRICT_KERNEL_RWX breaks booting on P9 DD1 without fixes that
are not yet merged. This does not regress op-build master as
hostboot removed support as of 5f13c60.
