This might need a newer gcc version that generates slightly smaller code, or maybe a newer binutils version that packs it tighter. > 2. Allwinner H6 PMIC issue > > (repost from ports@, same as > https://marc.info/?l=openbsd-ports&m=167133709916806&w=2) > > Some Allwinner H6 based board does not work ethernet and HDMI > (currently not used) due to improper setting of AXP805 PMIC. > > To avoid this issue, Armbian uses old ATF (v2.2). Our ATF ports cannot > downgrade, so using SUNXI_SETUP_REGULATORS=0 option to disable PMIC > handling in ATF. > > This option is discussed at ATF's code review, see > https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/12676 > > To reduce side-effect of this change, it is the best that compiling both > (SUNXI_SETUP_REGULATORS=0 and 1) bl31 object separately, but looks > difficult. > > So this suggestion is fixed to 0, please tell me if there is better idea.
