It's a fix for a usecase that already exists (we already enable the eMMC on A83T), and it's unusable on some boards without it. Maxime

But none of A83T boards were not enable eMMC yet? even sun8i-a83t.dtsi still need to add node. May be we can wait once all add? # grep -R 83T configs/ configs/Sinovoip_BPI_M3_defconfig:CONFIG_MACH_SUN8I_A83T=y configs/h8_homlet_v2_defconfig:CONFIG_MACH_SUN8I_A83T=y configs/Cubietruck_plus_defconfig:CONFIG_MACH_SUN8I_A83T=y thanks!

May be we can wait once all add? The sunxi-mmc driver does not use the device tree. One only needs to set CONFIG_MMC_SUNXI_SLOT_EXTRA=2 to use the eMMC. And yes, eMMC is broken on some boards unless the new timing mode is used.

And the support is broken until "mmc: sunxi: fix legacy MMC initialisation" in my other serie is applied. Maxime

With these patches, eMMC detected BPI-M3. But none of A83T boards have CONFIG_MMC_SUNXI_SLOT_EXTRA=2 So it's better to take this once boards added. thanks!

That argument doesn't really stand, any user is able to modify the configuration themself, and experience that breakage. The fact that this is not enabled by default just make it less exposed, but it's still a bug that can be encountered today in a real-life situation. Maxime
