Two new sections for IRAM usage: .irodata (selectable with the ICONST_ATTR attribute macro), allowing to put 'const' data into IRAM without causing a section type conflict, and .ibss (selectable with the IBSS_ATTR attribute macro) for uninitialised data. * Rockbox core: Adjusted the linker scripts and init code to not include the .ibss section in the binary, it is cleared instead. Saves ~500 bytes on archos and ~30KB on iriver. Codecs and plugins don't handle .ibss in a special way yet. * The init code properly handles empty sections now (except .stack, which should never be empty). * Unified the init code for SH1 and coldfire a bit.
