From 21d08b9d5536ac418bbce4f419fe2b528b7ddf31 Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Sat, 23 Apr 2011 15:28:34 +0800 Subject: at91: introduce commom AT91_BASE_SYS On all at91 except rm9200 and x40 have the System Controller starts at address 0xffffc000 and has a size of 16KiB. On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting at 0xfffff000 This patch removes the individual definitions of AT91_BASE_SYS and replaces them with a common version at base 0xfffffc000 and size 16KiB and map the same memory space Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD Cc: Nicolas Ferre Cc: Patrice Vilchez --- arch/arm/mach-at91/at91sam9rl.c | 22 ++++++++-------------- 1 file changed, 8 insertions(+), 14 deletions(-) (limited to 'arch/arm/mach-at91/at91sam9rl.c') diff --git a/arch/arm/mach-at91/at91sam9rl.c b/arch/arm/mach-at91/at91sam9rl.c index 29dff18ed130..8ff7720b3e4a 100644 --- a/arch/arm/mach-at91/at91sam9rl.c +++ b/arch/arm/mach-at91/at91sam9rl.c @@ -21,18 +21,10 @@ #include #include +#include "soc.h" #include "generic.h" #include "clock.h" -static struct map_desc at91sam9rl_io_desc[] __initdata = { - { - .virtual = AT91_VA_BASE_SYS, - .pfn = __phys_to_pfn(AT91_BASE_SYS), - .length = SZ_16K, - .type = MT_DEVICE, - }, -}; - static struct map_desc at91sam9rl_sram_desc[] __initdata = { { .pfn = __phys_to_pfn(AT91SAM9RL_SRAM_BASE), @@ -287,13 +279,10 @@ static void at91sam9rl_poweroff(void) * AT91SAM9RL processor initialization * -------------------------------------------------------------------- */ -void __init at91sam9rl_map_io(void) +static void __init at91sam9rl_map_io(void) { unsigned long cidr, sram_size; - /* Map peripherals */ - iotable_init(at91sam9rl_io_desc, ARRAY_SIZE(at91sam9rl_io_desc)); - cidr = at91_sys_read(AT91_DBGU_CIDR); switch (cidr & AT91_CIDR_SRAMSIZ) { @@ -312,7 +301,7 @@ void __init at91sam9rl_map_io(void) iotable_init(at91sam9rl_sram_desc, ARRAY_SIZE(at91sam9rl_sram_desc)); } -void __init at91sam9rl_initialize(unsigned long main_clock) +static void __init at91sam9rl_initialize(unsigned long main_clock) { at91_arch_reset = at91sam9_alt_reset; pm_power_off = at91sam9rl_poweroff; @@ -381,3 +370,8 @@ void __init at91sam9rl_init_interrupts(unsigned int priority[NR_AIC_IRQS]) /* Enable GPIO interrupts */ at91_gpio_irq_setup(); } + +struct at91_soc __initdata at91sam9rl_soc = { + .map_io = at91sam9rl_map_io, + .init = at91sam9rl_initialize, +}; -- cgit v1.2.1
