2019-11-20include/device: add a comment to pci mmio cfg addr helpers and cachingMichael Niewöhner
Add a comment to the newly introduced MMIO address helpers for PCI config registers, that the pointer returned may change during the boot processs and, thus, must not be cached.

2019-04-07device/pci: Rewrite PCI MMCONF with symbol referenceKyösti Mälkki
The effect of pointer aliasing on writes is that any data on CPU registers that has been resolved from (non-const and non-volatile) memory objects has to be discarded and resolved. In other words, the compiler assumes that a pointer that does not have an absolute value at build-time, and is of type 'void *' or 'char *', may write over any memory object. Using a unique datatype for MMIO writes makes the pointer to _not_ qualify for pointer aliasing with any other objects in memory. This avoid constantly resolving the PCI MMCONF address, which is a derived value from a 'struct device *'.
