*	mx5: Mark lowlevel_init board-specific code	Benoît Thébaudeau	2012-11-19	-0/+5
\| \| \| \| \| \| \| \| \| \| \| \|	The mx5 lowlevel_init.S contains board-specific code based on the reference design. Let's keep it since it avoids creating new lowlevel_init files and it may be used by many boards. But add a config to make it optional in order not to cause issues on boards not following this part of the reference design.

*	ARM: MX51: PLL errata workaround	David Jander	2011-09-04	-0/+17
	This is a port of the official PLL errata workaround from Freescale to mainline u-boot. The PLL's in the i.MX51 processor can go out of lock due to a metastable condition in an analog flip-flop when used at high frequencies. This workaround implements an undocumented feature in the PLL (dither mode), which causes the effect of this failure to be much lower (in terms of frequency deviation), avoiding system failure, or at least decreasing the likelihood of system failure.
