Add a patch to disable uImage generation to avoid depend on u-boot-tools
Fix typo the EL's flavor names in installer: not same within defines
Malta is never used for r6. (Closes: #898523)
Boston also requires relocation table size >= 0x00121000
Although the choice of CPU type currently only applies to Malta
flavours, there's nothing in these config files that prevents them
being used with other platforms (that we don't currently support).
