[U-Boot] about rk3399 boot speed
Hi Philipp,
When I test on firefly-rk3399 with latest mainline U-Boot, it boots very very slow,
and it's due to the first time of cru driver bind(U-Boot proper) and the clk_set_defaults() cost about 5S.
Does puma board has the same problem?
Thanks,
- Kever
Hi Kever,
I can confirm that current master behaves the same on Puma. For a fix please take a look at: https://patchwork.ozlabs.org/patch/1003412/

Kever,
A fix is in Simon’s queue. One of the early picks from the merge window caused this. The details are in the patch that Klaus referenced...
Thanks, Philipp.
