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 5272 UART addressing so that: . UARTs are numbered from 0 up . base addresses are absolute (not relative to MBAR peripheral register) Signed-off-by: Greg Ungerer <[email protected]> --- arch/m68k/include/asm/m5272sim.h | 8 ++++---- arch/m68k/platform/5272/config.c | 8 ++++---- 2 files changed, 8 insertions(+), 8 deletions(-) diff --git a/arch/m68k/include/asm/m5272sim.h b/arch/m68k/include/asm/m5272sim.h index 759c2b0..5c71bd4 100644 --- a/arch/m68k/include/asm/m5272sim.h +++ b/arch/m68k/include/asm/m5272sim.h @@ -68,8 +68,8 @@ #define MCFSIM_DCMR1 0x5c /* DRAM 1 Mask reg (r/w) */ #define MCFSIM_DCCR1 0x63 /* DRAM 1 Control reg (r/w) */ -#define MCFUART_BASE1 0x100 /* Base address of UART1 */ -#define MCFUART_BASE2 0x140 /* Base address of UART2 */ +#define MCFUART_BASE0 (MCF_MBAR + 0x100) /* Base address UART0 */ +#define MCFUART_BASE1 (MCF_MBAR + 0x140) /* Base address UART1 */ #define MCFSIM_PACNT (MCF_MBAR + 0x80) /* Port A Control (r/w) */ #define MCFSIM_PADDR (MCF_MBAR + 0x84) /* Port A Direction (r/w) */ @@ -101,8 +101,8 @@ #define MCF_IRQ_TIMER2 70 /* Timer 2 */ #define MCF_IRQ_TIMER3 71 /* Timer 3 */ #define MCF_IRQ_TIMER4 72 /* Timer 4 */ -#define MCF_IRQ_UART1 73 /* UART 1 */ -#define MCF_IRQ_UART2 74 /* UART 2 */ +#define MCF_IRQ_UART0 73 /* UART 0 */ +#define MCF_IRQ_UART1 74 /* UART 1 */ #define MCF_IRQ_PLIP 75 /* PLIC 2Khz Periodic */ #define MCF_IRQ_PLIA 76 /* PLIC Asynchronous */ #define MCF_IRQ_USB0 77 /* USB Endpoint 0 */ diff --git a/arch/m68k/platform/5272/config.c b/arch/m68k/platform/5272/config.c index 65bb582..99b499e 100644 --- a/arch/m68k/platform/5272/config.c +++ b/arch/m68k/platform/5272/config.c @@ -32,12 +32,12 @@ unsigned char ledbank = 0xff; static struct mcf_platform_uart m5272_uart_platform[] = { { - .mapbase = MCF_MBAR + MCFUART_BASE1, - .irq = MCF_IRQ_UART1, + .mapbase = MCFUART_BASE0, + .irq = MCF_IRQ_UART0, }, { - .mapbase = MCF_MBAR + MCFUART_BASE2, - .irq = MCF_IRQ_UART2, + .mapbase = MCFUART_BASE1, + .irq = MCF_IRQ_UART1, }, { }, }; -- 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
