[Xen-devel] [RFC PATCH] xen/arm: remove check for generic timer support for arm64

[vijay.kilari@xxxxxxxxx]

From: Vijaya Kumar K <Vijaya.Kumar@xxxxxxxxxxxxxxxxxx>

Information about support for generic support is available in
IDR_PFR1 register in ARMv7. Where as this information is not
available in ARMv8 that supports only aarch64 bit mode.
ARMv8 being always supports generic timer, this check is not
required.

For platforms that support only aarch64 mode, IDR_PFR1 is
not implemented
