[PATCH v2 05/12] hw/block/pflash_cfi02: Open-code pflash_register_memory(rom=false)
Posted by Philippe Mathieu-Daudé 4 years, 11 months ago
There is only one call to pflash_register_memory() with
rom_mode == false. As we want to modify pflash_register_memory()
in the next patch, open-code this trivial function in place for
the 'rom_mode == false' case.
