[Qemu-devel] [PATCH V5 5/7] Add max device width parameter for NOR devices

2013-12-05 Thread Roy Franz
For handling CFI and device ID reads, we need to not only know the width that a NOR flash device is configured for, but also its maximum width. The maximum width addressing mode is used for multi-width parts no matter which width they are configured for. The most common case is x16 parts that als
