[v4,01/26] hw/ppc/e500: Do not leak struct boot_info

Commit Message

Bernhard Beschow Nov. 3, 2024, 1:33 p.m. UTC

The struct is allocated once with g_new0() but never free()'d. Fix the leakage
by adding an attribute to struct PPCE500MachineState which avoids the
allocation.

While at it remove the obsolete /*< private >*/ markers.
