Change RMA size from 512 MB to 768 MB which will result

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

[1/1] powerpc: increase MIN RMA size for CAS negotiation

I posted a patch series that includes this patch along with patches to
avoid the impact on fadump due to the `MIN_RMA` change introduced in
this patch.

The patches in the above patch series are arranged to ensure they do not
break `git bisect`. Previously, we tested this patch and the fadump
changes together but sent them separately, which I now realize was not
the best approach. If possible, please consider accepting the entire
patch series as a whole.

We have included test cases for the above patch series and a changelog
explaining additional details in the cover letter. Please let me know if
you have queries regarding this. Thanks, Sourabh Jain
