Those default settings usually make the MMU behave like it did in older ARM versions, when some options were not yet available and hence, the entire system was simpler. Our project uses C bitfield structs for operating on SCTLR and TTBCR contents and translation table descriptors. With DACR - bit shifts are more appropriate and with TTBCR - our default configuration means we're writing '0' to that register. This is an elegant and readable approach, yet little-portable across compilers. Current struct definitions work properly with GCC. |
