This patch adds esp-hosted-ng package that allows to build Linux Kernel
Driver for Espressif Esp32-* SoCs, that once programmed with the
corresponding firmware behave like a normal Wi-Fi module. Both SDIO and
SPI busses are supported and selectable.

I don't understand why it was named esp-hosted-ng, the upstream Github
repo is just esp-hosted. Yes, recent versions are "ng", but we normally
don't name our packages according to the versions, except in some very
specific cases (libgtk3, qt5, qt6, etc.). So I renamed everything to
esp-hosted (hoping I didn't mess up anything in the process) and
applied. It built fine against a vexpress_defconfig ARM32 Linux 6.1
kernel.
Thanks!
Thomas

The reason is that they keep two completely different firmware and Linux drivers depending on the sdio implementation and some months ago they kept NG(802.11 direct IF) and FG(802.3+protobuf apis to setup 802.11 stuff) as branches, but yes they changed it.
Anyway possibly one could use(even if it makes few sense) the FG. But then we only need to download exactly esp-hosted and that’s it.
I think I’ve been biased from the past git handling with 2 branches. In case someone is interested we can add 2 Config.in choices between FG and NG.
Very unlikely but… who knows.
FG is more MCU oriented(even if it supports Linux as 802.3+protobuf) while NG is very more Linux oriented since it has 802.11 IF.
Thank you for taking care of this patch.
There should be a new release in some time to add other SoCs to NG so I will bump it and I’m designing a Linux embedded board with an ESP32 on it for this use.
Best regards
Giulio
