am335x supports various sysclk frequencies which can be determined using sysboot pins. PLLs should be configures based on this sysclk frequency. Add PLL configurations for all supported frequencies.

Applied to u-boot/master, thanks!

Hello,
This appears to break beaglebone black support, reverting this commit make u-boot works again.
hmm..I see the problem. Here we are hard coding MPU freq to 1GHz even efuse say it is not supported(I am not sure why this is being done, may be Tom can give more details). Even in kernel I see that cpufreq is reading efuse to determine mpu frequency. Now that we have jitter optimized pll configurations, looks like unsupported freq is causing an issue. Can you see if the below patch helps?
In the kernel, we are re-enabling the 1GHz option in the BoneBlack's device tree blob:
