Still, we could go the other way and just define more smaller sections instead and simply drop this patch. (Assuming that the correspondence of sections and memory banks is irrelevant.) -- Best regards, Tomasz Figa -- To unsubscribe from this list: send the line unsubscribe linux-samsung-soc in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH v2 4/5] ARM: EXYNOS: Increase maximum possible memory bank size to 512MiB
Some boards have larger memory banks than 256MiB. This patch increses maximum bank size for Exynos-based boards to 512MiB.
