[U-Boot] question: U-boot linking against libgcc
by Remy Bohmer 04 Nov '08

Hello Wolfgang, In U-boot I see that it links against libgcc. Why is this? I believe this relation should not be needed. I could provide a patch to remove this relation... Kind Regards, Remy

[U-Boot] [PATCH] drivers/qe/uec_phy.c: Added PHY-less (fixed PHY) driver.
by Richard Retanubun 04 Nov '08

04 Nov '08

Copied over the fixed PHY driver as used in pp4xx/4xx_enet.c. This adds support for PHY-less MAC connections to the UEC.

[U-Boot] [patch] U-Boot Firetux board support
by Juergen Schoew 03 Nov '08

03 Nov '08

Hi U-Boot mailling list, This patchset adds a new ARM board with the NXP PNX8181 cpu to u-boot. The PNX8181 is an ARM926ej with an internal DSP and a baseband processor (used for DECT). The chip also features dual ethernet, digital to analog interface, spi, i2c and other SOC peripherals. The patch is against u-boot commit 055b12f2ffd7c34eea7e983a0588b24f2e69e0e3 (Date: Sun Oct 19 21:54:30 2008 +0200) but should apply to newer commits as well, because the code is mostly seperated. If you have any comments please email to me. Is is possible to include that patch in the new version of u-boot? Regards Jürgen Schöw -- Dipl.-Ing.

[U-Boot] [PATCH] powerpc 86xx: Handle CCSR relocation earlier
by Becky Bruce 03 Nov '08

03 Nov '08

Currently, the CCSR gets relocated while translation is enabled, meaning we need 2 BAT translations to get to both the old location and the new location. Also, the DEFAULT CCSR location has a dependency on the BAT that maps the FLASH region. Moving the relocation removes this unnecessary dependency. This makes it easier and more intutive to modify the board's memory map.

[U-Boot] [PATCH] mpc8641: Make PCI and RIO mutually exclusive, fix non-PCI build
by Becky Bruce 03 Nov '08

You can't actually have both, and with some coming changes to change the memory map for the board and support 36-bit physical, we need the extra BAT that is being consumed by having both. I also make non-PCI configs build cleanly, for the sake of sanity.

[U-Boot] [PATCH] 8641HPCN: Config file cleanup

There are several items in the config file that were hardcoded but that should really be based on other config options, since the regions are contiguous and depend on being so. This cleans that up a bit. Also, add BR_PHYS_ADDR() macro to convert addresses into the proper format for BR registers.

[U-Boot] [PATCH v4] Update U-Boot's build timestamp on every compile
by Peter Tyser 03 Nov '08

03 Nov '08

Use the GNU 'date' command to auto-generate a new U-Boot timestamp on every compile. Signed-off-by: Peter Tyser <ptyser(a)xes-inc.com> --- Changes since v1: * Split up U_BOOT_DATE define (date and time) into U_BOOT_DATE (day, month, year) and U_BOOT_TIME (time of day) defines * Updated all architetures/boards Changes since v2: * Placed U_BOOT_DATE and U_BOOT_TIME defines in timestamp_autogenerated.h. * Added include/timestamp.h Changes since v3: * rebased on TOT * removed 2 whitespace violations Makefile | 19 +++++++++++++------ board/bmw/bmw.c | 4 ++-- board/eXalion/eXalion.c | 3 ++- board/lwmon/lwmon.c | 3 ++- board/mousse/mousse.c | 3 ++- board/netstar/eeprom.c | 3 ++- board/sandburst/karef/karef.c | 6 ++++-- board/sandburst/metrobox/metrobox.c | 6 ++++-- board/tqc/tqm8xx/tqm8xx.c | 3 ++- board/trab/trab_fkt.c | 3 ++- board/voiceblue/eeprom.c | 3 ++- cpu/74xx_7xx/start.S | 3 ++- cpu/leon2/start.S | 3 ++- cpu/leon3/start.S | 3 ++- cpu/mcf5227x/start.S | 3 ++- cpu/mcf523x/start.S | 3 ++- cpu/mcf52x2/start.S | 3 ++- cpu/mcf532x/start.S | 3 ++- cpu/mcf5445x/start.S | 3 ++- cpu/mcf547x_8x/start.S | 3 ++- cpu/mpc512x/start.S | 3 ++- cpu/mpc5xx/start.S | 3 ++- cpu/mpc5xxx/start.S | 3 ++- cpu/mpc8220/start.S | 3 ++- cpu/mpc824x/start.S | 3 ++- cpu/mpc8260/start.S | 3 ++- cpu/mpc83xx/start.S | 3 ++- cpu/mpc85xx/start.S | 3 ++- cpu/mpc86xx/start.S | 3 ++- cpu/mpc8xx/start.S | 3 ++- cpu/mpc8xx/video.c | 4 +++- cpu/nios/start.S | 3 ++- cpu/nios2/start.S | 3 ++- cpu/ppc4xx/start.S | 3 ++- include/.gitignore | 1 + include/configs/NETPHONE.h | 2 +- include/configs/NETTA.h | 2 +- include/configs/NETTA2.h | 2 +- include/timestamp.h | 30 ++++++++++++++++++++++++++++++ lib_arm/board.c | 3 ++- lib_avr32/board.c | 3 ++- lib_blackfin/board.c | 3 ++- lib_i386/board.c | 3 ++- lib_microblaze/board.c | 3 ++- lib_mips/board.c | 3 ++- lib_sh/board.c | 3 ++- net/net.c | 3 +++ 47 files changed, 135 insertions(+), 52 deletions(-) create mode 100644 include/timestamp.h diff --git a/Makefile b/Makefile index d6abb4d..1ef46a9 100644 --- a/Makefile +++ b/Makefile @@ -30,6 +30,7 @@ U_BOOT_VERSION = $(VERSION).$(PATCHLEVEL).$(SUBLEVEL)$(EXTRAVERSION) else U_BOOT_VERSION = $(VERSION).$(PATCHLEVEL)$(EXTRAVERSION) endif +TIMESTAMP_FILE = $(obj)include/timestamp_autogenerated.h VERSION_FILE = $(obj)include/version_autogenerated.h HOSTARCH := $(shell uname -m | \ @@ -259,7 +260,7 @@ LIBS += api/libapi.a LIBS += post/libpost.a LIBS := $(addprefix $(obj),$(LIBS)) -.PHONY : $(LIBS) $(VERSION_FILE) +.PHONY : $(LIBS) $(TIMESTAMP_FILE) $(VERSION_FILE) LIBBOARD = board/$(BOARDDIR)/lib$(BOARD).a LIBBOARD := $(addprefix $(obj),$(LIBBOARD)) @@ -351,13 +352,13 @@ $(SUBDIRS): depend $(obj)include/autoconf.mk $(LDSCRIPT): depend $(obj)include/autoconf.mk $(MAKE) -C $(dir $@) $(notdir $@) -$(NAND_SPL): $(VERSION_FILE) $(obj)include/autoconf.mk +$(NAND_SPL): $(TIMESTAMP_FILE) $(VERSION_FILE) $(obj)include/autoconf.mk $(MAKE) -C nand_spl/board/$(BOARDDIR) all $(U_BOOT_NAND): $(NAND_SPL) $(obj)u-boot.bin $(obj)include/autoconf.mk cat $(obj)nand_spl/u-boot-spl-16k.bin $(obj)u-boot.bin > $(obj)u-boot-nand.bin -$(ONENAND_IPL): $(VERSION_FILE) $(obj)include/autoconf.mk +$(ONENAND_IPL): $(TIMESTAMP_FILE) $(VERSION_FILE) $(obj)include/autoconf.mk $(MAKE) -C onenand_ipl/board/$(BOARDDIR) all $(U_BOOT_ONENAND): $(ONENAND_IPL) $(obj)u-boot.bin $(obj)include/autoconf.mk @@ -370,6 +371,12 @@ $(VERSION_FILE): ) > $@.tmp @cmp -s $@ $@.tmp && rm -f $@.tmp || mv -f $@.tmp $@ +$(TIMESTAMP_FILE): + @( printf '#define U_BOOT_DATE "%s"\n' '$(shell date +"%b %d %C%y")' \ + ) > $@ + @( printf '#define U_BOOT_TIME "%s"\n' '$(shell date +"%T")' \ + ) >> $@ + gdbtools: $(MAKE) -C tools/gdb all || exit 1 @@ -379,7 +386,7 @@ updater: env: $(MAKE) -C tools/env all MTD_VERSION=${MTD_VERSION} || exit 1 -depend dep: $(VERSION_FILE) +depend dep: $(TIMESTAMP_FILE) $(VERSION_FILE) for dir in $(SUBDIRS) ; do $(MAKE) -C $$dir _depend ; done TAG_SUBDIRS += include @@ -460,7 +467,7 @@ sinclude $(obj)include/autoconf.mk.dep else # !config.mk all $(obj)u-boot.hex $(obj)u-boot.srec $(obj)u-boot.bin \ $(obj)u-boot.img $(obj)u-boot.dis $(obj)u-boot \ -$(SUBDIRS) $(VERSION_FILE) gdbtools updater env depend \ +$(SUBDIRS) $(TIMESTAMP_FILE) $(VERSION_FILE) gdbtools updater env depend \ dep tags ctags etags cscope $(obj)System.map: @echo "System not configured -
