[PATCH] [linux-next] ARM: mvebu: make DTS comments reflect DEBUG_LL changes

[PATCH] [linux-next] ARM: mvebu: make DTS comments reflect DEBUG_LL changes

[Paul Bolle]

The Kconfig symbol DEBUG_MVEBU_UART_ALTERNATE was renamed to
DEBUG_MVEBU_UART0_ALTERNATE. And the symbol DEBUG_MVEBU_UART1_ALTERNATE
was added to allow UART1 as a DEBUG_LL target. Make the comment at the
top of this DTS reflect those changes.

Since we're touching this DTS add comments to show which blocks describe
UART0 and UART1.

Created on top of next-20150119. Untested! Note that I know nothing
about this board or about DT source files, so all changes are nothing
more than guesses.

Hi Paul

Thanks for this. I have added it to mvebu/dt.
