Subject: [PATCH 1/5] net: ethernet: mtk_wed: fix firmware loading for MT7986
|
|
SoC
|
|
|
|
The WED mcu firmware does not contain all the memory regions defined in
|
|
the dts reserved_memory node (e.g. MT7986 WED firmware does not contain
|
|
cpu-boot region).
|
|
Reverse the mtk_wed_mcu_run_firmware() logic to check all the fw
|
|
sections are defined in the dts reserved_memory node.
|
|
|
|
Fixes: c6d961aeaa77 ("net: ethernet: mtk_wed: move mem_region array out of mtk_wed_mcu_load_firmware")
