Re: [PATCH] lmb: prohibit allocations above ram_top even from same bank

There are platforms which set the value of ram_top based on certain restrictions that the platform might have in accessing memory above ram_top, even when the memory region is in the same DRAM bank. So, even though the LMB allocator works as expected, when trying to allocate memory above ram_top, prohibit this by marking all memory above ram_top as reserved, even if the said memory region is from the same bank.

This fixes the boot failure on the VisionFive2 board as reported in mvm8qtnv310.fsf@suse.de.
