Wider testing now points to a known SDIO issue (SoC bug) with Amlogic G12A/B hardware. The merged workaround for the bug was only tested with bcmdhd and brcmfmac may require tweaking as the same issue exhibits on an Amlogic G12B device with BCM4356 chip. Testing the series with Amlogic GXM (older) and SM1 (newer) hardware to exclude the SoC bug shows everything working as expected.
