Cédric Le Goater	fc2527fb02	ppc/pnv: fix check on return value of blk_getlength() ... blk_getlength() returns an int64_t but the result is stored in a uint32_t. Errors (negative values) won't be caught by the check in pnv_pnor_realize() and blk_blockalign() will allocate a very large buffer in such cases. Fixes Coverity issue CID 1412226.

Cédric Le Goater	ca661fae81	ppc/pnv: Add HIOMAP commands ... This activates HIOMAP support on the QEMU PowerNV machine. The PnvPnor model is used to access the flash contents. The model simply maps the contents at a fix offset and enables or disables the mapping.

Cédric Le Goater	35dde57662	ppc/pnv: Add a PNOR model ... On a POWERPC PowerNV system, the host firmware is stored in a PNOR flash chip which contents is mapped on the LPC bus. This model adds a simple dummy device to map the contents of a block device in the host address space.
