powerpc/85xx: Don't report SRAM to L2 cache fallback as error (8ebf506a) · Commits · 戴 / test

If the SRAM region parameters are missing the SRAM driver probing exits and the L2 region is configured as L2 cache entirely. This is the expected default behaviour, so it makes no sense to report it as an error. Signed-off-by:
