[U-Boot] [PATCH 1/3] ARM: sunxi: Move watchdog register definitions to separate file

Chen-Yu Tsai
2014-10-04T12:37:26Z

On later Allwinner SoCs, the watchdog hardware is by all means a
separate hardware block, with its own address range and interrupt
line.

Move the register definitions to a separate file to facilitate
supporting newer SoCs.
