Hi Chris,

The ATAGS is used for passing parameter from bootloader to kernel at first, which has been replaced by DTB now for ARM platform.

And Rockchip using ATAGs for passing parameter like dram memory size/board uart in different boot process like DRAM init binary/ TPL/SPL to U-Boot since 2018.

And almost at the same time, Simon add bloblist for mainline U-Boot which for similar purpose.

So I'm not sure if this ATAGS should be accept in mainline U-Boot or not, even for rockchip platform only seems some kind of regression for this feature support.

Hi Simon and Tom,

Could you help to give some suggestion for this?

This should be using bloblist, yes, as I understand it.
