From 220a96f9926788ed531717f78e44fdf1e7ab3b34 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Thu, 30 Dec 2010 22:45:29 +0100 Subject: rework architecture / embedded systems concept Make configuration of new targets cheap. Just add a new file in target/arch/sys-enabled/foo. See other files for syntax. While doing runtime tests with the new infrastructure I've updated a lot of other stuff: - gcc 4.5.2 - uClibc 0.9.32-rc1 (NPTL) - strongswan, php, miredo, parted, util-linux-ng, e2fsprogs I promise, this is the last big fat commit this year ;) --- target/linux/patches/2.6.36/cris.patch | 5736 ++++++++++++++++++++++++++++++++ 1 file changed, 5736 insertions(+) create mode 100644 target/linux/patches/2.6.36/cris.patch (limited to 'target/linux/patches/2.6.36/cris.patch') diff --git a/target/linux/patches/2.6.36/cris.patch b/target/linux/patches/2.6.36/cris.patch new file mode 100644 index 000000000..6be88fc18 --- /dev/null +++ b/target/linux/patches/2.6.36/cris.patch @@ -0,0 +1,5736 @@ +diff -Nur linux-2.6.36.orig/arch/cris/Kconfig linux-2.6.36/arch/cris/Kconfig +--- linux-2.6.36.orig/arch/cris/Kconfig 2010-10-20 22:30:22.000000000 +0200 ++++ linux-2.6.36/arch/cris/Kconfig 2010-12-28 20:35:16.000000000 +0100 +@@ -177,6 +177,12 @@ + help + Size of DRAM (decimal in MB) typically 2, 8 or 16. + ++config ETRAX_MTD_SIZE ++ hex "MTD size (hex)" ++ default "0x00800000" ++ help ++ Size of MTD device typically 4 or 8 MB. ++ + config ETRAX_VMEM_SIZE + int "Video memory size (dec, in MB)" + depends on ETRAX_ARCH_V32 && !ETRAXFS +@@ -282,7 +288,7 @@ + select MTD_CFI_AMDSTD + select MTD_JEDECPROBE if ETRAX_ARCH_V32 + select MTD_CHAR +- select MTD_BLOCK ++ select MTD_BLOCK_RO + select MTD_PARTITIONS + select MTD_CONCAT + select MTD_COMPLEX_MAPPINGS +@@ -671,6 +677,11 @@ + + source "drivers/ide/Kconfig" + ++#mysteriously part of this standard linux driver was removed from cris build! - info@crisos.org ++source "drivers/scsi/Kconfig" ++ ++source "drivers/media/Kconfig" ++ + source "drivers/net/Kconfig" + + source "drivers/i2c/Kconfig" +@@ -686,6 +697,8 @@ + + source "fs/Kconfig" + ++source "sound/Kconfig" ++ + source "drivers/usb/Kconfig" + + source "drivers/uwb/Kconfig" +diff -Nur linux-2.6.36.orig/arch/cris/Makefile linux-2.6.36/arch/cris/Makefile +--- linux-2.6.36.orig/arch/cris/Makefile 2010-10-20 22:30:22.000000000 +0200 ++++ linux-2.6.36/arch/cris/Makefile 2010-12-28 20:35:00.000000000 +0100 +@@ -40,10 +40,10 @@ + + LD = $(CROSS_COMPILE)ld -mcrislinux + +-OBJCOPYFLAGS := -O binary -R .note -R .comment -S ++OBJCOPYFLAGS := -O binary -R .bss -R .note -R .note.gnu.build-id -R .comment -S + + KBUILD_AFLAGS += -mlinux -march=$(arch-y) $(inc) +-KBUILD_CFLAGS += -mlinux -march=$(arch-y) -pipe $(inc) ++KBUILD_CFLAGS += -mlinux -march=$(arch-y) -pipe -fno-peephole2 $(inc) + KBUILD_CPPFLAGS += $(inc) + + ifdef CONFIG_FRAME_POINTER +diff -Nur linux-2.6.36.orig/arch/cris/arch-v10/drivers/axisflashmap.c linux-2.6.36/arch/cris/arch-v10/drivers/axisflashmap.c +--- linux-2.6.36.orig/arch/cris/arch-v10/drivers/axisflashmap.c 2010-10-20 22:30:22.000000000 +0200 ++++ linux-2.6.36/arch/cris/arch-v10/drivers/axisflashmap.c 2010-12-28 20:35:00.000000000 +0100 +@@ -113,7 +113,7 @@ + + /* If no partition-table was found, we use this default-set. */ + #define MAX_PARTITIONS 7 +-#define NUM_DEFAULT_PARTITIONS 3 ++#define NUM_DEFAULT_PARTITIONS 4 + + /* + * Default flash size is 2MB.
