[PATCH v3 0/9] memory: assert and define MemoryRegionOps callbacks

From: Prasad J Pandit [email protected]

Hello,

* This series asserts that MemoryRegionOps objects define read/write callback methods. Thus avoids potential NULL pointer dereference. ex. -> https://git.qemu.org/?p=qemu.git;a=commit;h=bb15013ef34617eb1344f5276292cadd326c21b2

* Also adds various undefined MemoryRegionOps read/write functions to avoid potential assert failure.

Thank you.
