You appear to have MEMMAP_SETTINGS and VMWARE_SETTINGS enabled in 

MEMMAP_SETTINGS relies on the BIOS e820 memory map and so is not 
available under UEFI.  The equivalent functionality to retrieve the UEFI 
memory map is not implemented.

VMWARE_SETTINGS is currently i386-only, but I can't see any good reason 
for this.  I don't have a 64-bit UEFI VMware VM to test with, but I've 
pushed an experimental branch to


Could you try this branch in a 64-bit UEFI VMware VM with 
VMWARE_SETTINGS and/or CONSOLE_VMWARE enabled, and let me know if the 
features work as expected?
