[U-Boot] [PATCH] powerpc/85xx: Add workaround for erratum CPU-A011 on e500mc cores
by Kumar Gala 27 Aug '11

27 Aug '11

Issue: CoreNet bad data signal is not sent with shared data from L1 Data Cache when it has an error Workaround: Run in write-shadow mode by setting L1CSR2[DCWS] = 1 By default we do NOT enable this, thus we have #undef in config_mpc85xx.h for this erratum.
