From: Mike Frysinger Date: Wed, 21 Nov 2007 08:12:12 +0000 (+0800) Subject: Blackfin arch: cplb and map header file cleanup X-Git-Tag: v2.6.24-rc4~95^2~11 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3a9f435ae1b1969736a6ca695dfbc508b917b65;p=linux-2.6 Blackfin arch: cplb and map header file cleanup - remove duplicated defines for the BF561 - generalize L2 support (so that it works for BF54x) and mark it executable - add support for reading/executing the Boot ROM sections (since it has data/functions we may need at runtime) - and fixup names for each map Signed-off-by: Mike Frysinger Signed-off-by: Bryan Wu --- diff --git a/arch/blackfin/kernel/cplbinit.c b/arch/blackfin/kernel/cplbinit.c index 959b510c5f..6320bc45fb 100644 --- a/arch/blackfin/kernel/cplbinit.c +++ b/arch/blackfin/kernel/cplbinit.c @@ -64,7 +64,7 @@ static struct cplb_desc cplb_data[] = { #else .valid = 0, #endif - .name = "ZERO Pointer Saveguard", + .name = "Zero Pointer Guard Page", }, { .start = L1_CODE_START, @@ -95,20 +95,20 @@ static struct cplb_desc cplb_data[] = { .end = 0, /* dynamic */ .psize = 0, .attr = INITIAL_T | SWITCH_T | I_CPLB | D_CPLB, - .i_conf = SDRAM_IGENERIC, - .d_conf = SDRAM_DGENERIC, + .i_conf = SDRAM_IGENERIC, + .d_conf = SDRAM_DGENERIC, .valid = 1, - .name = "SDRAM Kernel", + .name = "Kernel Memory", }, { .start = 0, /* dynamic */ .end = 0, /* dynamic */ .psize = 0, .attr = INITIAL_T | SWITCH_T | D_CPLB, - .i_conf = SDRAM_IGENERIC, - .d_conf = SDRAM_DNON_CHBL, + .i_conf = SDRAM_IGENERIC, + .d_conf = SDRAM_DNON_CHBL, .valid = 1, - .name = "SDRAM RAM MTD", + .name = "uClinux MTD Memory", }, { .start = 0, /* dynamic */ @@ -117,7 +117,7 @@ static struct cplb_desc cplb_data[] = { .attr = INITIAL_T | SWITCH_T | D_CPLB, .d_conf = SDRAM_DNON_CHBL, .valid = 1, - .name = "SDRAM Uncached DMA ZONE", + .name = "Uncached DMA Zone", }, { .start = 0, /* dynamic */ @@ -127,7 +127,7 @@ static struct cplb_desc cplb_data[] = { .i_conf = 0, /* dynamic */ .d_conf = 0, /* dynamic */ .valid = 1, - .name = "SDRAM Reserved Memory", + .name = "Reserved Memory", }, { .start = ASYNC_BANK0_BASE, @@ -136,14 +136,14 @@ static struct cplb_desc cplb_data[] = { .attr = SWITCH_T | D_CPLB, .d_conf = SDRAM_EBIU, .valid = 1, - .name = "ASYNC Memory", + .name = "Asynchronous Memory Banks", }, { -#if defined(CONFIG_BF561) - .start = L2_SRAM, - .end = L2_SRAM_END, +#ifdef L2_START + .start = L2_START, + .end = L2_START + L2_LENGTH, .psize = SIZE_1M, - .attr = SWITCH_T | D_CPLB, + .attr = SWITCH_T | I_CPLB | D_CPLB, .i_conf = L2_MEMORY, .d_conf = L2_MEMORY, .valid = 1, @@ -151,7 +151,17 @@ static struct cplb_desc cplb_data[] = { .valid = 0, #endif .name = "L2 Memory", - } + }, + { + .start = BOOT_ROM_START, + .end = BOOT_ROM_START + BOOT_ROM_LENGTH, + .psize = SIZE_1M, + .attr = SWITCH_T | I_CPLB | D_CPLB, + .i_conf = SDRAM_IGENERIC, + .d_conf = SDRAM_DGENERIC, + .valid = 1, + .name = "On-Chip BootROM", + }, };
