Subject: [PATCH] sun5i: Give PLL6 a sane initial value
The upstream kernel does not override PLL values as set by power-on-reset
and/or the bootloader if it can avoid doing so.
The power-on-reset value for PLL6 is 2400MHz, which does not actually work,
the kernel does not know this and 2400 / 48 is 50 MHz, so the kernel happily
tries to use it as is for mmc.
Set PLL6 to a working frequency so that the kernel can use it. This fixes
mmc in the upstream kernel not working on sun5i.

Subject: [PATCH] sun5i: Tweak pll6 init value
There are multiple ways to get 600 MHz from PLL6, the sun5i ccmu is very
similar to the sun4i and sun7i ccmu.
This commit changes the PLL6 initialization we do for sun5i to make the PLL6
reg value match that of sun4i and sun7i. This also makes it closer to the
sun5i power on default, as we are now only changing the K-factor from 3 to 1.

Subject: [PATCH] sunxi: A10-OLinuXino-Lime support fixup
Fix:
-code indentation
-dram timings, the used cas and tpr0 - tpr2 were typical sun5i / sun7i
settings, while they should be sun4i settings
-Properly sort boards.cfg entry
-Add status led support
