chromeos: provide option to dynamically allocate ram oops buffer
Fixing the location of the ram oops buffer can lead to certain kernel and boot loaders being confused when there is a ram reservation low in the address space. Alternatively provide a mechanism to allocate the ram oops buffer in cbmem. As cbmem is usually high in the address space it avoids low reservation confusion. The patch uncondtionally provides a GOOG9999 ACPI device with a single memory resource describing the memory region used for the ramoops region. BUG=None BRANCH=baytrail,haswell TEST=Built and booted with and w/o dynamic ram oops. With the corresponding kernel change things behave correctly.
