      [POWERPC] Fix Kexec/Kdump for power6 · b7abc5c5
      由 Sachin P. Sant 提交于 
      On Power machines supporting VRMA, Kexec/Kdump does not work.
VRMA (virtual real-mode area) means that accesses with IR/DR = 0
(i.e. the MMU "off") actually still go through the hash table,
using entries put there by the hypervisor.

This means that when we clear out the hash table on kexec, we need to
make sure these entries are left untouched.

This also adds plpar_pte_read_raw() on the lines of
plpar_pte_remove_raw().

      [POWERPC] Fix interrupt distribution in ppc970 · 7ccb4a66
      由 Mohan Kumar M 提交于 
      In some of the PPC970 based systems, interrupt would be distributed to
offline cpus also even when booted with "maxcpus=1".  So check whether
cpu online map and cpu present map are equal or not.  If they are equal
default_distrib_server is used as interrupt server otherwise boot cpu
(default_server) used as interrupt server.

In addition to this, if an interrupt is assigned to a specific cpu (ie
smp affinity) and if that cpu is not online, the earlier code used to
return the default_distrib_server as interrupt server.  This
introduces an additional parameter to the get_irq function, called
strict_check.  Based on this parameter, if the cpu is not online
either default_distrib_server or -1 is returned.

      [POWERPC] Update holly to use new dts wrapping feature · b0e80206
      由 Mark A. Greer 提交于 
      The holly support currently has separate rules to wrap its device tree
with its zImage.  This can now be done automatically without the extra
rules so update holly support to use the automatic feature.

      [POWERPC] pasemi: Electra IDE/pata_platform glue · 8fa336d8
      由 Olof Johansson 提交于 
      Glue code to hook up the pata_platform on the PA Semi Electra eval board.
CFE sets up device tree entries for the IDE interface, with device type
'ide' and compatible field 'electra-ide'.

We unfortunately need to modify the resources before calling the generic
platform driver, since the device tree only has one register window in
it and the driver expects two.  Adding this as an of_platform driver
instead doesn't give us any benefit, it just adds one more layer of
register/probe functions.

Since CONFIG_PATA_PLATFORM depends on CONFIG_EMBEDDED, add that as a
default for PPC_PASEMI.
