Patch d873133f [ppc4xx: Add Sequoia RAM-booting target] broke "normal" booting on some 44x platforms. This breakage is only noticed in some cases while powercycling. As it seems, the code in question in start.S didn't invalidate TLB #0. This makes sense since this TLB is used for the bootrom mapping. With the patch mentioned above even TLB #0 got invalidated resulting in an error later on.
This patch now fixes this issue by only invalidating TLB #0 in the RAM- booting case.
Tested succesfully on Sequoia and Canyonlands.
Applied to ppc4xx/master. Thanks.
Best regards, Stefan
