[U-Boot] PowerPC MPC8641x Erratum e600 5

[Jude Miller]

(primarily addressed to the Freescale U-Boot team)

MPC8641D Erratum e600 5 is a hardware problem with cache initialization
that occurs with all processor revisions prior to the new one, rev 3.0.

I've looked at cpu/mpc86xx/start.S in the current git tree and don't
see any code implementing the suggested software work-around. Is this
code already in U-Boot, in the works, or not planned for U-Boot?

Thanks,

Jude Miller
