[ Upstream commit 0309f714a0908e947af1c902cf6a330cb593e75e ] The sp804 is currently only user selectable if COMPILE_TEST, this was done by commitdfc82faad7("clocksource/drivers/sp804: Add COMPILE_TEST to CONFIG_ARM_TIMER_SP804") in order to avoid it being spuriously offered on platforms that won't have the hardware since it's generally only seen on Arm based platforms. This config is overly restrictive, while platforms that rely on the SP804 do select it in their Kconfig there are others such as the Arm fast models which have a SP804 available but currently unused by Linux. Relax the dependency to allow it to be user selectable on arm and arm64 to avoid surprises and in case someone comes up with a use for extra timer hardware.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
