I applied both these patches on top of u-boot-tegra/master, built for Ventana, and loaded/ran u-boot.bin, and don't see any useful serial output; there's a bit of periodic binary spew. u-boot-dtb.bin works as expected.
So, these patches don't appear to solve the problem.
You are seeing the output, but since it resets the ns16550 on every character we are just emitting garbage. I should have pushed back on just having a board_pre_console_panic() as it would be easier. Anyway, given that this is what we have, we need a function to drain the FIFO.
Also printf() is silently skipped without a console, so we need to stop that happening as well.
I will send a new series with those two new patches and dealing with Mike's comments. It seems to work fine for me on Seaboard.
Regards, Simon
