Memmap shows the available memory 0000000080A00000-000000009A6BBFFF that should be enough to load linux.
Why EFI Linux Loader allocate memory resource from start address 80800000? Could it allocate the memory resource from the available memory region?

I get the following error while loading the LEG-UEFI kernel [1] on a BeagleBone Black (omap2plus_defconfig + efi stub support) when the kernel requests memory from UEFI.:
Shell> zImage EFI stub: Booting Linux Kernel... ConvertPages: failed to find range 80800000 - 81FFFFFF EFI stub: ERROR: Unable to allocate memory for uncompressed kernel. EFI stub: ERROR: Failed to relocate kernel Error: Image at 0009A3F8000 start failed: Load Error Unloading driver at 0x0009A3F8000 Error reported: Load Error
`memmap` shows the map to have a gap from 80800000 - 81FFFFFF (PcdFdBaseAddress for BBB UEFI is 0x80800000, so that's where I have UEFI loaded).
Does this mean I should adjust the BBB memory map so that all external allocations are done *after* the UEFI region (possibly by reserving the lower addresses)? Is there an alternate way of getting the kernel up?
