Subject: efi/x86: Add debug code to print cooked memmap
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22c091d02a5422d2825a4fb1af71e5a62f9e4d0f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

efi/x86: Add debug code to print cooked memmap

It is not obvious if the reserved boot area are added correctly, add a
efi_print_memmap() call to print the new memmap.
