MIPS: ath79: Store the SoC revision in a global variable (be5f3623) · Commits · 戴 / test

Knowing the exact revision of the SoC is required to make runtime decisions in various code paths. We have determined the SoC revision already, so we only need to store that in a global variable. Signed-off-by:
