	  erratum 826319 on Cortex-A53 parts up to r0p2 with an AMBA 4 ACE or
	  AXI master interface and an L2 cache.

	  If a Cortex-A53 uses an AMBA AXI4 ACE interface to other processors
	  and is unable to accept a certain write via this interface, it will
	  not progress on read data presented on the read data channel and the
	  system can deadlock.

	  The workaround promotes data cache clean instructions to

	  This option adds an alternative code sequence to work around ARM
	  erratum 827319 on Cortex-A53 parts up to r0p2 with an AMBA 5 CHI
	  master interface and an L2 cache.

	  Under certain conditions this erratum can cause a clean line eviction
	  to occur at the same time as another transaction to the same address
	  on the AMBA 5 CHI interface, which can cause data corruption if the
	  interconnect reorders the two transactions.

	  The workaround promotes data cache clean instructions to

	  If a Cortex-A53 processor is executing a store or prefetch for

	  If the processor is executing a load and store exclusive sequence at

	  Affected Cortex-A57 parts might deadlock when exclusive load/store

	  The workaround is to promote device loads to use Load-Acquire

	  When running a compat (AArch32) userspace on an affected Cortex-A53
	  part, a load at EL0 from a virtual address that matches the bottom 32
	  bits of the virtual address used by a recent load at (AArch64) EL1

	  In some older versions of glibc [<=2.8] SWP is used during futex

	  be preempted. This invalid assumption may be more likely to fail
	  with SWP emulation enabled, leading to deadlock of the user
	  application.

	  NOTE: when accessing uncached shared regions, LDXR/STXR rely
	  on an external transaction monitoring block called a global
	  monitor to maintain update atomicity. If your system does not

	  instructions instead.

	  Say Y here to enable software emulation of these

	  Note: All the cpus on the system must have mixed endian support at EL0
