Re: [U-Boot] [PATCH] powerpc/mpc85xx: set L2PE in L2CSR0 before enabling L2 cache

While enabling L2 cache, the value of L2PE (L2 cache parity/ECC error checking enable) must not be changed while the L2 cache is enabled. So, L2PE must be set before enabling L2 cache.

Aneesh,

The original code set L2PE and L2E together. The L2PE bit doesn't change after that. Doesn't this satisfy the requirement? Did you observe any failure before your patch?
