So you get the feedback here.... We have at91_get_ddram_size(IOMEM(xxx), {true or false}) If we introduced the following small helpers we could simplify the call sites to just use at91_get_ddram_size(AT91SAM9G45_BASE_DDRSDRC0) and similar. static inline u32 at91_get_ddram_size(void __force __iomem * addr) { return __at91_get_ddram_size(IOMEM(addr), true); } static inline u32 at91sam9g45_get_ddram_size(void __force __iomem * addr) { return __at91_get_ddram_size(IOMEM(addr), false); } But then for the few call sites it is not really worth it anyway. Anyway, just a small itch. Just ignore it. Sam _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
