CONFIG_E500MC breaks e500/e500v2 systems. It defines L1_CACHE_SHIFT to 6, thus breaking clear_pages(), probably others too. Cc: Kumar Gala <redacted> Signed-off-by: Baruch Siach <baruch@tkos.co.il> --- Is this the right approach?It doesn't work for me. I need something that if an e500v2 platform (e.g. the P1022DS) is selected, then I won't be able to select any e500mc platforms (e.g. P4080DS). And if I don't select any e500v2 platforms, then I will be able to select an e500mc platform. This patch doesn't seem to do that.
The source of the trouble seems to be the user selectable CONFIG_PPC_E500MC with the misleading "e500mc Support" description. I'll try to post something better next week.
It might be necessary to split the entire menu into two parts, one for e500v2 parts and one for e500mc parts.
