Hi there, when I ugprade U-Boot from 2021-ish version (WIP/28Jan2021) to v2024.10 (with some trivial patches [1] [2]), my SolidRun Clearfog Base takes "ages" to boot. It looks like this is the same issue as Pali reported last year [3]. Apparently, the BootROM loads the SPL, which performs some work and passes control back to BootROM, at which time it hangs for about five minutes:
BootROM - 1.73
Booting from MMC

-> Can I do something to fix this?
