From 4926e989ac2f83bd887bee683c7e2c0481f5cd3a Mon Sep 17 00:00:00 2001 From: Jacob Garber Date: Fri, 26 Jul 2019 11:45:43 -0600 Subject: vc/cavium/{bdk,include}: Clean up bdk_phys_to_ptr() calls The bdk_phys_to_ptr() function converts a uint64_t address to a void * pointer. Judging by the comments, the old implementation had a check that would refuse to convert a null pointer, which required several workarounds when trying to convert the address 0 to a pointer. This isn't the case for coreboot though, which implements this function as a simple (void *) cast, so we can remove the old workarounds.
