Change RMA size from 512 MB to 768 MB which will result in more RMA at boot time for PowerPC. When PowerPC LPAR use/uses vTPM, Secure Boot or FADump, the 512 MB RMA memory is not sufficient for booting. With this 512 MB RMA, GRUB2 run out of memory and unable to load the necessary. Sometimes even usage of CDROM which requires more memory for installation along with the options mentioned above troubles the boot memory and result in boot failures. Increasing the RMA size will resolves multiple out of memory issues observed in PowerPC. [...]
Applied to powerpc/next.
