[U-Boot] mx6ul_14x14_evk

[Eric Nelson]

Hi Fabio, Peng, and all.

I just ran into a problem with bus frequency switching
on the EVK and there appears to be a U-Boot component.

Using the 4.1.15 kernel from git.freescale.com (commit a4d2a08)
and the latest U-Boot from Stefano's imx tree (commit a3e5519)
causes the EVK to hang during a bus frequency switch to LOW_POWER
mode.

The last gasp is this:
	Bus freq set to 24000000 start...

And the code block in question is here:
	http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-imx/busfreq_ddr3.c?h=imx_4.1.15_1.0.0_ga#n386

When using the binary U-Boot 2015.07 from the EVK package (commit
d7d7c43 from git.freescale.com), the kernel gets through the
frequency switch and produces this message.

	Bus freq set to 24000000 done!

I first saw this problem with u-boot-fslc branch v2016.07
and linux-fslc (4.1.29 and 4.1.30).

Has anybody else experienced this?

Please advise,


Eric
