Subject: [PATCH AUTOSEL 5.15 12/21] m68knommu: fix non-mmu classic 68000 legacy timer tick selection

From: Greg Ungerer <gerg@...ux-m68k.org>

[ Upstream commit 18011e50c497f04a57a8e00122906f04922b30b4 ]

The family of classic 68000 parts supported when in non-mmu mode all
currently use the legacy timer support. Move the selection of that config
option, LEGACY_TIMER_TICK, into the core CPU configuration.

This fixes compilation if no specific CPU variant is selected, since
the LEGACY_TIMER_TICK option was only selected in the specific CPU
variant configurations.
