unify version_string

2011-07-28T15:22:53Z

This patch removes the architecture specific implementation of version_string where possible. Some architectures use a special place and therefore we provide U_BOOT_VERSION_STRING definition and a common weak symbol version_string.

serial: drop useless ctlr field

2011-07-26T14:38:05Z

The multi serial support has a "ctlr" field which almost no one uses, but everyone is forced to set to useless strings. So punt it. Funny enough, the only code that actually reads this field (the mpc8xx driver) has a typo where it meant to look for the SCC driver. Fix it while converting the check to use the name field.

serial: push default_serial_console to drivers

2011-07-26T14:37:57Z

Rather than sticking arch/board/driver specific logic in the common serial code, push it all out to the respective drivers. The serial drivers declare these funcs weak so that boards can still override things with their own definition.

Revert "PowerPC: Add support for -msingle-pic-base"

2011-04-20T20:11:21Z

This reverts commit 39768f7715ed637ef02f49fc7de664cc1aaf14b3. Reson: it breaks a number of boards with embedded environment as the code size grows in some places.

PowerPC: Add support for -msingle-pic-base

2011-04-11T19:38:47Z

-msingle-pic-base is a new gcc option for ppc and it reduces the size of my u-boot with 6-8 KB. While at it, add -fno-jump-tables too to save a few more bytes. -msingle-pic-base will be in gcc 4.6, however backported patches are available at http://bugs.gentoo.org/show_bug.cgi?id=347281 Signed-off-by: Joakim Tjernlund

PowerPC: Move -fPIC flag to common place

2011-04-11T19:36:41Z

The -fPIC flag belongs with -mrelocatable, move it there. Also change -fPIC to -fpic as this produces smaller binaries. However, currently -mrelocatable promotes -fpic to -fPIC, a fix for this is in upcoming gcc 4.6 or you can apply this small patch to gcc: diff --git a/gcc/config/rs6000/sysv4.h b/gcc/config/rs6000/sysv4.h index 8da8410..e4b8280 100644 --- a/gcc/config/rs6000/sysv4.h +++ b/gcc/config/rs6000/sysv4.h @@ -227,7 +227,8 @@ do { \ } \ \ else if (TARGET_RELOCATABLE) \ - flag_pic = 2; \ + if (!flag_pic) \ + flag_pic = 2; \ } while (0) #ifndef RS6000_BI_ARCH -- Signed-off-by: Joakim Tjernlund

rename _end to __bss_end__

2011-03-27T17:18:37Z

Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang

miiphy: convert to linux/mii.h

2011-01-09T17:06:50Z

The include/miiphy.h header duplicates a lot of things from linux/mii.h. So punt all the things that overlap to keep the API simple and to make merging between U-Boot and Linux simpler. Signed-off-by: Mike Frysinger

arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings work

2010-11-26T21:08:19Z

As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.
