  doc: uefi: add HTTP Boot support (2023-11-18 10:08:09 +0200)

EFI HTTP Boot is currently supported by using a combination of
wget, blkmap and bootefi commands. The user has to download the
image, mount it using blkmap and then execute the efi installer
using bootefi.
This series simplifies the user experience. Instead of doing all the
steps manually, users can now enable a new Kconfig (EFI_HTTP_BOOT)
which will select wget, blkmap and dns options. They can then use
efidebug command to add a boot option for the EFI Bootmanager using
=> efidebug boot add -u 3 netinst http://<path>
=> efidebug boot order 3
=> bootefi bootmgr

The boot manager will automatically download and mount the image.
Once it's mounted it will locate and launch the installer.

It's worth noting that this rarely fails, but the reason is irrelevant
to the current patchset. More information can be found here
https://lore.kernel.org/u-boot/CAOMZO5CoduEgwgdQiybmoKh6qQZOezUtRRQO4ecaGdZBBz5dDw@mail.gmail.com/
The tl;dr is that wget sometimes fails to download the file correctly
or set the size env variables. We expect all these to be solved once
LWIP is stable and pulled

The CI reported no issues
