So modify the ColdFire 523x UART addressing so that: . UARTs are numbered from 0 up . use a common name for IRQs used Signed-off-by: Greg Ungerer --- arch/m68k/include/asm/m523xsim.h | 12 +++++++++--- arch/m68k/platform/523x/config.c | 12 ++++++------ 2 files changed, 15 insertions(+), 9 deletions(-) diff --git a/arch/m68k/include/asm/m523xsim.h b/arch/m68k/include/asm/m523xsim.h index 6235921..919d115 100644 --- a/arch/m68k/include/asm/m523xsim.h +++ b/arch/m68k/include/asm/m523xsim.h @@ -35,9 +35,15 @@ #define MCFINT_VECBASE 64 /* Vector base number */ #define MCFINT_UART0 13 /* Interrupt number for UART0 */ +#define MCFINT_UART1 14 /* Interrupt number for UART1 */ +#define MCFINT_UART2 15 /* Interrupt number for UART2 */ #define MCFINT_PIT1 36 /* Interrupt number for PIT1 */ #define MCFINT_QSPI 18 /* Interrupt number for QSPI */ +#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. */ @@ -59,9 +65,9 @@ /* * UART module. */ -#define MCFUART_BASE1 (MCF_IPSBAR + 0x200) -#define MCFUART_BASE2 (MCF_IPSBAR + 0x240) -#define MCFUART_BASE3 (MCF_IPSBAR + 0x280) +#define MCFUART_BASE0 (MCF_IPSBAR + 0x200) +#define MCFUART_BASE1 (MCF_IPSBAR + 0x240) +#define MCFUART_BASE2 (MCF_IPSBAR + 0x280) /* * FEC ethernet module. diff --git a/arch/m68k/platform/523x/config.c b/arch/m68k/platform/523x/config.c index 71f4436..c01d0ae 100644 --- a/arch/m68k/platform/523x/config.c +++ b/arch/m68k/platform/523x/config.c @@ -28,16 +28,16 @@ static struct mcf_platform_uart m523x_uart_platform[] = { { - .mapbase = MCFUART_BASE1, - .irq = MCFINT_VECBASE + MCFINT_UART0, + .mapbase = MCFUART_BASE0, + .irq = MCF_IRQ_UART0, }, { - .mapbase = MCFUART_BASE2, - .irq = MCFINT_VECBASE + MCFINT_UART0 + 1, + .mapbase = MCFUART_BASE1, + .irq = MCF_IRQ_UART1, }, { - .mapbase = MCFUART_BASE3, - .irq = MCFINT_VECBASE + MCFINT_UART0 + 2, + .mapbase = MCFUART_BASE2, + .irq = MCF_IRQ_UART2, }, { }, }; -- 1.7.0.4
