[PATCH 02/15] habanalabs: add MMU DRAM default page mapping

From: Omer Shpigelman This patch provides a workaround for a H/W bug in Goya, where access to RAZWI from TPC can cause PCI completion timeout. The WA is to use the device MMU to map any unmapped DRAM memory to a default page in the DRAM. That way, the TPC will never reach RAZWI upon accessing a

[PATCH 05/15] habanalabs: fix validation of WREG32 to DMA completion
