WRT for uz801

These are my attempts at building the os... my end goal is to build a working modern openwrt, but first I will start from immortalwrt from lkiuyu and the from official immortalwrt.

lkiuyu/immortalwrt

• Modem Working
  • No Rx/Tx displayed in luci interface (?)
• Wifi Working
• USB gadget working (NCM, RNDIS, MASS, ACM tested!)

TODO:

• Recover GHA build pipeline
• Use built dtb from openstick-builder?
  • use linux's dts?
• modemmanager not showing rxtx
• Use mcopy and debugfs compiled by openwrt:

    include $(TOPDIR)/rules.mk
  
    PKG_NAME:=foo
    PKG_RELEASE:=1
    PKG_BUILD_DEPENDS:=mtools/host
  
    include $(INCLUDE_DIR)/package.mk
  
    define Package/foo
      SECTION:=utils
      CATEGORY:=Utilities
      TITLE:=Foo example using mcopy
    endef
  
    # Ejemplo: crear/usar una imagen FAT en tiempo de build
    define Build/Compile
      # crea directorio dentro de la imagen
      $(STAGING_DIR_HOST)/bin/mmd   -i $(PKG_BUILD_DIR)/fs.img ::/etc
      # copia un archivo a la imagen sin usar mcopy del sistema
      $(STAGING_DIR_HOST)/bin/mcopy -i $(PKG_BUILD_DIR)/fs.img $(PKG_BUILD_DIR)/my.conf ::/etc/my.conf
    endef
  
    define Package/foo/install
      $(INSTALL_DIR) $(1)/usr/share/foo
      $(INSTALL_DATA) $(PKG_BUILD_DIR)/fs.img $(1)/usr/share/foo/
    endef
  
    $(eval $(call BuildPackage,foo))
