* ppc/pnv: fix check on return value of blk_getlength()Cédric Le Goater2020-01-081-1/+1
| | | | | | | | | | | | | | | 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.

* ppc/pnv: check return value of blk_pwrite()Cédric Le Goater2020-01-081-2/+6
| | | | | | | | | | | | | When updating the PNOR file contents, we should check for a possible failure of blk_pwrite(). Fixes Coverity issue CID 1412228.

* ppc/pnv: Add a PNOR modelCédric Le Goater2019-12-171-0/+135
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.
