From: Greg Ungerer <[email protected]> If we make all UART addressing consistent across all ColdFire family members then we will be able to remove the duplicated plaform data and use a single setup for all.
So modify the ColdFire 520x UART addressing so that: . UARTs are numbered from 0 up . use a common name for IRQs used Signed-off-by: Greg Ungerer <[email protected]> --- arch/m68k/include/asm/m520xsim.h | 10 +++++++--- arch/m68k/platform/520x/config.c | 12 ++++++------ 2 files changed, 13 insertions(+), 9 deletions(-) diff --git a/arch/m68k/include/asm/m520xsim.h b/arch/m68k/include/asm/m520xsim.h index eda62de..41ed4dc 100644 --- a/arch/m68k/include/asm/m520xsim.h +++ b/arch/m68k/include/asm/m520xsim.h @@ -50,6 +50,10 @@ #define MCFINT_QSPI 31 /* Interrupt number for QSPI */ #define MCFINT_PIT1 4 /* Interrupt number for PIT1 (PIT0 in processor) */ +#define MCF_IRQ_UART0 (MCFINT_VECBASE + MCFINT_UART0) +#define MCF_IRQ_UART1 (MCFINT_VECBASE + MCFINT_UART1) +#define MCF_IRQ_UART2 (MCFINT_VECBASE + MCFINT_UART2) + /* * SDRAM configuration registers. */ @@ -144,9 +148,9 @@ /* * UART module. */ -#define MCFUART_BASE1 0xFC060000 /* Base address of UART1 */ -#define MCFUART_BASE2 0xFC064000 /* Base address of UART2 */ -#define MCFUART_BASE3 0xFC068000 /* Base address of UART2 */ +#define MCFUART_BASE0 0xFC060000 /* Base address of UART0 */ +#define MCFUART_BASE1 0xFC064000 /* Base address of UART1 */ +#define MCFUART_BASE2 0xFC068000 /* Base address of UART2 */ /* * FEC module. diff --git a/arch/m68k/platform/520x/config.c b/arch/m68k/platform/520x/config.c index 8a98683..9dc4870 100644 --- a/arch/m68k/platform/520x/config.c +++ b/arch/m68k/platform/520x/config.c @@ -27,16 +27,16 @@ static struct mcf_platform_uart m520x_uart_platform[] = { { - .mapbase = MCFUART_BASE1, - .irq = MCFINT_VECBASE + MCFINT_UART0, + .mapbase = MCFUART_BASE0, + .irq = MCF_IRQ_UART0, }, { - .mapbase = MCFUART_BASE2, - .irq = MCFINT_VECBASE + MCFINT_UART1, + .mapbase = MCFUART_BASE1, + .irq = MCF_IRQ_UART1, }, { - .mapbase = MCFUART_BASE3, - .irq = MCFINT_VECBASE + MCFINT_UART2, + .mapbase = MCFUART_BASE2, + .irq = MCF_IRQ_UART2, }, { }, }; -- 1.7.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
