From 658e81701970a82d33f46241f20be416ebd5e930 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Sat, 15 Sep 2007 04:54:11 +1000 Subject: [PATCH] [POWERPC] cuimage for Bamboo board Add a cuboot wrapper for the Bamboo board. Additionally, we enable MAC address fixups for both cuboot and treeboot. This also removes some obsoleted linker declarations that have been moved into ops.h Signed-off-by: Josh Boyer Acked-by: David Gibson --- arch/powerpc/boot/44x.h | 2 +- arch/powerpc/boot/Makefile | 4 ++-- arch/powerpc/boot/bamboo.c | 8 +++++--- arch/powerpc/boot/cuboot-bamboo.c | 30 +++++++++++++++++++++++++++++ arch/powerpc/boot/treeboot-bamboo.c | 22 ++++++++++++++++++--- 5 files changed, 57 insertions(+), 9 deletions(-) create mode 100644 arch/powerpc/boot/cuboot-bamboo.c diff --git a/arch/powerpc/boot/44x.h b/arch/powerpc/boot/44x.h index ad33dcc95ae5..02563443788a 100644 --- a/arch/powerpc/boot/44x.h +++ b/arch/powerpc/boot/44x.h @@ -11,6 +11,6 @@ #define _PPC_BOOT_44X_H_ void ebony_init(void *mac0, void *mac1); -void bamboo_init(void); +void bamboo_init(void *mac0, void *mac1); #endif /* _PPC_BOOT_44X_H_ */ diff --git a/arch/powerpc/boot/Makefile b/arch/powerpc/boot/Makefile index cffef147e042..c1582b62911c 100644 --- a/arch/powerpc/boot/Makefile +++ b/arch/powerpc/boot/Makefile @@ -49,7 +49,7 @@ src-wlib := string.S crt0.S stdio.c main.c flatdevtree.c flatdevtree_misc.c \ src-plat := of.c cuboot-83xx.c cuboot-85xx.c holly.c \ cuboot-ebony.c treeboot-ebony.c prpmc2800.c \ ps3-head.S ps3-hvcall.S ps3.c treeboot-bamboo.c cuboot-8xx.c \ - cuboot-pq2.c cuboot-sequoia.c treeboot-walnut.c + cuboot-pq2.c cuboot-sequoia.c treeboot-walnut.c cuboot-bamboo.c src-boot := $(src-wlib) $(src-plat) empty.c src-boot := $(addprefix $(obj)/, $(src-boot)) @@ -146,7 +146,7 @@ image-$(CONFIG_8260) += cuImage.pq2 image-$(CONFIG_PPC_83xx) += cuImage.83xx image-$(CONFIG_PPC_85xx) += cuImage.85xx image-$(CONFIG_EBONY) += treeImage.ebony cuImage.ebony -image-$(CONFIG_BAMBOO) += treeImage.bamboo +image-$(CONFIG_BAMBOO) += treeImage.bamboo cuImage.bamboo image-$(CONFIG_SEQUOIA) += cuImage.sequoia image-$(CONFIG_WALNUT) += treeImage.walnut endif diff --git a/arch/powerpc/boot/bamboo.c b/arch/powerpc/boot/bamboo.c index bc097694b445..f61fcdab1c7c 100644 --- a/arch/powerpc/boot/bamboo.c +++ b/arch/powerpc/boot/bamboo.c @@ -24,8 +24,7 @@ #include "4xx.h" #include "44x.h" -extern char _dtb_start[]; -extern char _dtb_end[]; +static u8 *bamboo_mac0, *bamboo_mac1; static void bamboo_fixups(void) { @@ -34,12 +33,15 @@ static void bamboo_fixups(void) ibm440ep_fixup_clocks(sysclk, 11059200); ibm4xx_fixup_memsize(); ibm4xx_quiesce_eth((u32 *)0xef600e00, (u32 *)0xef600f00); + dt_fixup_mac_addresses(bamboo_mac0, bamboo_mac1); } -void bamboo_init(void) +void bamboo_init(void *mac0, void *mac1) { platform_ops.fixups = bamboo_fixups; platform_ops.exit = ibm44x_dbcr_reset; + bamboo_mac0 = mac0; + bamboo_mac1 = mac1; ft_init(_dtb_start, 0, 32); serial_console_init(); } diff --git a/arch/powerpc/boot/cuboot-bamboo.c b/arch/powerpc/boot/cuboot-bamboo.c new file mode 100644 index 000000000000..900c7ff2b7e9 --- /dev/null +++ b/arch/powerpc/boot/cuboot-bamboo.c @@ -0,0 +1,30 @@ +/* + * Old U-boot compatibility for Bamboo + * + * Author: Josh Boyer + * + * Copyright 2007 IBM Corporation + * + * Based on cuboot-ebony.c + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License version 2 as published + * by the Free Software Foundation. + */ + +#include "ops.h" +#include "stdio.h" +#include "44x.h" +#include "cuboot.h" + +#define TARGET_44x +#include "ppcboot.h" + +static bd_t bd; + +void platform_init(unsigned long r3, unsigned long r4, unsigned long r5, + unsigned long r6, unsigned long r7) +{ + CUBOOT_INIT(); + bamboo_init(&bd.bi_enetaddr, &bd.bi_enet1addr); +} diff --git a/arch/powerpc/boot/treeboot-bamboo.c b/arch/powerpc/boot/treeboot-bamboo.c index 1f1fe5aaac12..9eee48fc7114 100644 --- a/arch/powerpc/boot/treeboot-bamboo.c +++ b/arch/powerpc/boot/treeboot-bamboo.c @@ -12,16 +12,32 @@ #include "ops.h" #include "stdio.h" #include "44x.h" - -extern char _end[]; +#include "stdlib.h" BSS_STACK(4096); +#define PIBS_MAC0 0xfffc0400 +#define PIBS_MAC1 0xfffc0500 +char pibs_mac0[6]; +char pibs_mac1[6]; + +static void read_pibs_mac(void) +{ + unsigned long long mac64; + + mac64 = strtoull((char *)PIBS_MAC0, 0, 16); + memcpy(&pibs_mac0, (char *)&mac64+2, 6); + + mac64 = strtoull((char *)PIBS_MAC1, 0, 16); + memcpy(&pibs_mac1, (char *)&mac64+2, 6); +} + void platform_init(void) { unsigned long end_of_ram = 0x8000000; unsigned long avail_ram = end_of_ram - (unsigned long)_end; simple_alloc_init(_end, avail_ram, 32, 64); - bamboo_init(); + read_pibs_mac(); + bamboo_init((u8 *)&pibs_mac0, (u8 *)&pibs_mac1); } -- 2.20.1
