Resource constrained by other priorities is not surprising in my view.

had the sysutils/u-boot-rpi4 based workaround (as seen in its build =
tree):

# diff ./board/raspberrypi/rpi/rpi.c.orig ./board/raspberrypi/rpi/rpi.c
485c485
< 	efi_add_memory_map(0, 1, EFI_RESERVED_MEMORY_TYPE, 0);
---
> 	efi_add_memory_map(0, 2, EFI_RESERVED_MEMORY_TYPE, 0);

It just changes EFI interfacing to indicate the first 2 pages as
reserved instead of indicating just 1 page as reserved.

I did not convert it to a form appropriate for
/usr/ports/sysutils/u-boot-rpi4/files/ . I simply changed
the source after the fetch patch sequence but before
building and later showed the diff. Better form for
adapting to a normal files/* patch would be (up to whitespace
details possibly not being fully preserved):

# cd /wrkdirs/usr/ports/sysutils/u-boot-rpi4/work/u-boot-2019.10/
# diff -U3 board/raspberrypi/rpi/rpi.c.orig board/raspberrypi/rpi/rpi.c

(The /wrkdirs style prefix is something I cause in my environments
in order to match poudriere paths when it makes tar files that I
sometimes expand. So that need not be duplicated/used.)

I have not looked at sysutils/u-boot-rpi3 . I'd expect something
similar for it.
