* ppc: Update README about the new GOT ptr.Joakim Tjernlund2010-01-26-1/+3
| | | | | | | | r14 is no longer used as non volatile GOT ptr. Instead the volatile r12 is used so be sure to do GET_GOT in asm code when you need to access global data. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>

* smc911x: update SMC911X related configuration descriptionMike Rapoport2009-12-07-5/+5
| | | | | | | | | Since commit 736fead8fdbf8a8407048bebc373cd551d01ec98 "Convert SMC911X Ethernet driver to CONFIG_NET_MULTI API" SMC911X configration options are called CONFIG_SMC911X rather than CONFIG_DRIVER_SMC911X.

* Add 'editenv' commandPeter Tyser2009-10-27-0/+1
| | | | | | | | | The editenv command can be used to edit an environment variable. Editing an environment variable is useful when one wants to tweak an existing variable, for example fix a typo or change the baudrate in the 'bootargs' environment variable.

* Revert "env: only build env_embedded and envcrc when needed"Wolfgang Denk2009-10-27-5/+0
| | | | | | Breaks building on many boards, and no really clean fix available yet. This reverts commit 6dab6add2d8ee80905234b326abc3de11be1d178.
* env: only build env_embedded and envcrc when neededMike Frysinger2009-10-18-0/+5
| | | | | | | | | | | | | The env code is protected by the ENV_IS_EMBEDDED define, so attempting to compile the code when this isn't defined is pointless. Now that the env headers have unified around CONFIG_ENV_IS_EMBEDDED, convert the build system to only build the env objects when this is enabled. And now that the env code is conditionally compiled, we can drop the source code checks. For people who want to extract the environment manually, add a new option CONFIG_BUILD_ENVCRC that only enables the envcrc utility. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* mucmc52, uc101: delete ata@3a00 node, if no CF card is detectedHeiko Schocher2009-09-25-0/+9
| | | | | | | | | | | U-Boot can detect if an IDE device is present or not. If not, and this new config option is activated, U-Boot removes the ATA node from the DTS before booting Linux, so the Linux IDE driver does not probe the device and crash. This is needed for buggy hardware (uc101) where no pull down resistor is connected to the signal IDE5V_DD7. Signed-off-by: Heiko Schocher <hs@denx.de>
* Remove deprecated 'autoscr' command/variablesPeter Tyser2009-09-22-8/+0
| | | | | | | | | | | | | | | The more standard 'source' command provides identical functionality to the autoscr command. Environment variable names/values on the MVBC_P, MVBML7, kmeter1, mgcoge, and km8xx boards are updated to no longer refernce 'autoscr'. The 'autoscript' and 'autoscript_uname' environment variables are also removed.

* Reset i2c slave devices during init on mpc5xxx cpusEric Millbrandt2009-09-06-0/+7
| | | | | | | | | | | Reset any i2c devices that may have been interrupted during a system reset. Normally this would be accomplished by clocking the line until SCL and SDA are released and then sending a start condtiion (From an Atmel datasheet). There is no direct access to the i2c pins so instead create start commands through the i2c interface. Send a start command then delay for the SDA Hold time, repeat this by disabling/enabling the bus a total of 9 times. Signed-off-by: Eric Millbrandt <emillbrandt@dekaresearch.com>
* Blackfin: change global data register from P5 to P3Robin Getz2009-09-02-2/+2
| | | | | | | | | | | Since the Blackfin ABI favors higher scratch registers by default, use the last scratch register (P3) for global data rather than the first (P5). This allows the compiler's register allocator to use higher number scratch P registers, which in turn better matches the Blackfin instruction set, which reduces the size of U-Boot by more than 1024 bytes...

* Add support for USB on PSC3 for the mpc5200Eric Millbrandt2009-08-25-0/+4
| | | | | | | | | | | Support USB on PSC3 on the mpc5200. Before this patch, enabling USB support would reconfigure PSC4 and PSC5 to USB. The mpc5200 does not support USB enabled on both the standard USB port and PSC3. This patch masks the appropriate bits when enabling USB.

| | | | | | | | | | | | | | | Linux's netconsole works much better when you can pass it the MAC address of the server. (otherwise it just uses broadcast, which everyone else on my network complains about :) This sets the env var "serveraddr" (to match ethaddr), so that you can pass it to linux with whatever bootargs you want to.... addnetconsole=set bootargs $(bootargs) netconsole=@$(ipaddr)/eth0,@$(serverip)/$(serveraddr) Signed-of-by: Robin Getz <rgetz@blackfin.uclinux.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

| * Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

* nand_spl: read environment early, when booting from NAND using nand_splGuennadi Liakhovetski2009-07-07-0/+6
| | | | | | | | | | | | Currently, when booting from NAND using nand_spl, in the beginning the default environment is used until later in boot process the dynamic environment is read out. This way environment variables that must be interpreted early, like the baudrate or "silent", cannot be modified dynamically and remain at their default values. Fix this problem by reading out main and redundand (if used) copies of the environment in the nand_spl code.

* mtd: Introduce CONFIG_MTD_DEVICE to select compilation of mtdcore.oStefan Roese2009-06-12-0/+11
| | | | | | | | | | | | | This new define enables mtdcore.c compilation and with this we can select the MTD device infrastructure needed for the reworked mtdparts command. We now have the 2 MTD infrastructure defines, CONFIG_MTD_DEVICE and CONFIG_MTD_PARTITIONS. CONFIG_MTD_DEVICE is needed (as explained above) for the "mtdparts" command and CONFIG_MTD_PARTITIONS is needed for UBI.

* Add support for building native win32 toolsPeter Tyser2009-04-04-0/+10
| | | | | | | | | | | | | Add support for compiling the host tools in the tools directory using the MinGW toolchain. This produces executables which can be used on standard Windows computers without requiring cygwin. One must specify the MinGW compiler and strip utilities as if they were the host toolchain in order to build win32 executables, eg: make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Add "source" command; prepare removal of "autoscr" commandWolfgang Denk2009-04-03-5/+5
| | | | | | | | | | | | | | | | | | | | | According to the doc/feature-removal-schedule.txt, the "autoscr" command will be replaced by the "source" command in approximately 6 months from now. This patch prepares this change and starts a 6 month transition period as follows: - The new "source" command has been added, which implements exactly the same functionlaity as the old "autoscr" command before - The old "autoscr" command name is kept as an alias for compatibility - Command sequences, script files atc. have been adapted to use the new "source" command - Related environment variables ("autoscript", "autoscript_uname") have *not* been adapted yet; these will be renamed resp. removed in a separate patch when the support for the "autoscr" command get's finally dropped.

* Separate mtdparts command from jffs2Stefan Roese2009-03-20-0/+1
| | | | | | | | | | | Currently the mtdparts commands are included in the jffs2 command support. This doesn't make sense anymore since other commands (e.g. UBI) use this infrastructure as well now.

This option will exclude all functions with exception of NS16550_putc and NS16550_init. This will be used primarily to save space and remove unused code from builds in which space is limited.

* soft_i2c.c add option for repeated start in i2c_read()Andrew Dyer2009-01-27-0/+9
| | | | | | | | | | | | | | | | This patch adds a #define to optionally change the behaviour of i2c_read() in soft_i2c.c to send an I2C repeated start instead of a stop-start between sending the device address pointer write and reading back the data. The current behaviour is retained as the default. While most devices will work either way, I have a smart battery(*) that requires repeated start, and someone at some point found a device that required a stop-start.
