Change RMA size from 512 MB to 768 MB which will result in more memory at boot time for PowerPC. When vTPM, Secure Boot or FADump are enabled on PowerPC the 512 MB RMA memory is not sufficient for boot. With this 512 MB RMA, GRUB runs out of memory and fails to boot the machine. Sometimes even usage of CDROM requires more memory for installation and along with the options mentioned above exhausts the boot memory which results in boot failures. Increasing the RMA size will resolves multiple out of memory issues observed on PowerPC machines.
