[PATCH V4 12/23] at91: Make UART devices common
Ryan Mallon
ryan at bluewatersys.com
Mon May 2 20:03:26 EDT 2011
Replace the individual UART, including debug UART, code for each at91
variiant with a single implementation in devices.c
The original code used the interrupt numbers for the UARTs as unique
identifiers. Because the interrupt numbers differ between the AT91
variants we introduce a new enum for the UART ids. The AT91_UARTx
names are already used by the early UART code as the base address of
the UART, so we cannot use those names. Instead we introduce
AT91_UART_DBGU and AT91_UART_USx.
