      powerpc/eeh: Don't unfreeze PHB PE after reset · 527d10ef
      由 Gavin Shan 提交于 
      On PowerNV platform, the PE is kept in frozen state until the PE
reset is completed to avoid recursive EEH error caused by MMIO
access during the period of EEH reset. The PE's frozen state is
cleared after BARs of PCI device included in the PE are restored
and enabled. However, we needn't clear the frozen state for PHB PE
explicitly at this point as there is no real PE for PHB PE. As the
PHB PE is always binding with PE#0, we actually clear PE#0, which
is wrong. It doesn't incur any problem though.

This checks if the PE is PHB PE and doesn't clear the frozen state
if it is.

      powerpc/ps3: Quieten boot wrapper output with run_cmd · 879c26d4
      由 Geoff Levand 提交于 
      Add a boot wrapper script function run_cmd which will run a shell command
quietly and only print the output if either V=1 or an error occurs.

Also, run the ps3 dd commands with run_cmd to clean up the build output.

      powerpc/prom: Avoid reference to potentially freed memory · 1856f50c
      由 Christophe Jaillet 提交于 
      of_get_property() is used inside the loop, but then the reference to the
node is dropped before dereferencing the prop pointer, which could by then
point to junk if the node has been freed.

Instead use of_property_read_u32() to actually read the property
value before dropping the reference.

of_property_read_u32() requires at least one cell (u32) to be present,
which is stricter than the old logic which would happily dereference a
property of any size. However we believe all device trees in the wild
have at least one cell.

Skiboot may produce memory nodes with more than one cell, but that is
OK, of_property_read_u32() will return the first one.
