Hi,

I am using the Mainline with the aarch64 gcc from Ubuntu 22.04. I am over by ~1100 bytes with LTO enabled, but I'm going through my SPL drivers to see what I can either remove or reduce functionality.
Try
$ aarch64...readelf -s spl/u-boot-spl | sort -nk 3
That should give you a list of large symbols you might want to inspect.
Thank you!
Adam,
I'm curious what you find as my SPL for imx8mm_venice_defconfig also overflows by about 3K when enabling what's needed here for SDP as well. I have 4 different dram configs which are chewing up about 1K each.
Tim,
I have it building successfully now, and it loads over USB. I had to disable BD718x7 PMIC children binding which required a small change to the PMIC driver [1]. I then removed HS400, HS200 and UHS support in SPL. Once I did all that, the code size fit into SPL space.

I'll try to push my patch today or tomorrow. I was doing some other clean-up, but I might just push that as a small series in itself.
Adam,
Yes, I have already done those same things for imx8mm_venice but am still 3K over due to my 4x dram configs. Each dram config must be about 3K as I only have to remove one of them to successfully build.
Thanks,
Tim
