The erratum titled “Disabling of data prefetcher with outstanding
prefetch TLB miss might cause a deadlock” should not be handled within
TF-A. The current workaround attempts to follow option 2 but
misapplies it. Specifically, it statically sets PF_MODE to
conservative, which is not the recommended approach. According to the
erratum documentation, PF_MODE should be configured in conservative
mode only when we disable data prefetcher however this is not done
in TF-A and thus the workaround is not needed in TF-A.

The static setting of PF_MODE in TF-A does not correctly address the
erratum and may introduce unnecessary performance degradation on
platforms that adopt it without fully understanding its implications.

To prevent incorrect or unintended use, the current implementation of
this erratum workaround should be removed from TF-A and not adopted by
platforms.

The erratum titled “Disabling of data prefetcher with outstanding
prefetch TLB miss might cause a deadlock” should not be handled within
TF-A. The current workaround attempts to follow option 2 but
misapplies it. Specifically, it statically sets PF_MODE to
conservative, which is not the recommended approach. According to the
erratum documentation, PF_MODE should be configured in conservative
mode only when we disable data prefetcher however this is not done
in TF-A and thus the workaround is not needed in TF-A.

The static setting of PF_MODE in TF-A does not correctly address the
erratum and may introduce unnecessary performance degradation on
platforms that adopt it without fully understanding its implications.

To prevent incorrect or unintended use, the current implementation of
this erratum workaround should be removed from TF-A and not adopted by
platforms.
