* Rename getenv_r() into getenv_f()Wolfgang Denk2010-08-04-1/+1
| | | | | | | | | | | | | | | | | | | While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* Make *printf() return "int" instead of "void"Wolfgang Denk2010-07-04-4/+4
| | | | | | | | | | Change the return type of the *printf() functions to the standard "int"; no changes are needed but returning the already available length count. This will save a few additional strlen() calls later... Signed-off-by: Wolfgang Denk <wd@denx.de>

* Make getenv_IPaddr() globalDirk Behme2010-01-17-0/+7
| | | | | | | | | | | | | | | | | | | There are boards out there that do not have network support in U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This makes it desirable to be able to port network configuration (like the IP address) to the Linux kernel. We should not make the passing of the IP configuration to Linux dependent on U-Boot features / settings. For this, make getenv_IPaddr() global. This fixes build error u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr' on various architectures.

* Generic udelay() with watchdog supportIngo van Lil2009-12-05-1/+4
| | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>

* 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>

* Make include/common.h usable by assembler codeWolfgang Denk2009-07-27-17/+20
| | | | | | | | | | | | | | Commit 70ebf316 factored out the ROUND() macro into include/common.h, not realizing that the primary use of this macro on AT91 systems was in start.S where common.h was not included, and could not be included because it contains a lot of C code which the assembler doesn't understand. This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__" construct, and then adds an include to cpu/arm926ejs/start.S thus solving the problem. Signed-off-by: Wolfgang Denk <wd@denx.de>

* MPC512x: remove include/mpc512x.hWolfgang Denk2009-06-12-2/+1
| | | | | | | | | | | | | | | | | | | | Move needed definitions (register descriptions etc.) from include/mpc512x.h into include/asm-ppc/immap_512x.h. Instead of using a #define'd register offset, use a function that provides the PATA controller's base address. All the rest of include/mpc512x.h are register offset definitions which can be eliminated by proper use of C structures. There are only a few register offsets remaining that are needed in cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h which is intended as a temporary workaround only. In a later patch this file will be removed, too, and then auto-generated from the respective C structs. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>

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.

* IOMUX: Add console multiplexing support.Gary Jennejohn2008-12-07-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | Modifications to support console multiplexing. This is controlled using CONFIG_SYS_CONSOLE_MUX in the board configuration file. This allows a user to specify multiple console devices in the environment with a command like this: setenv stdin serial,nc. As a result, the user can enter text on both the serial and netconsole interfaces. All devices - stdin, stdout and stderr - can be set in this manner. 1) common/iomux.c and include/iomux.h contain the environment setting implementation. 2) doc/README.iomux contains a somewhat more detailed description. 3) The implementation in (1) is called from common/cmd_nvedit.c to handle setenv and from common/console.c to handle initialization of input/output devices at boot time. 4) common/console.c also contains the code needed to poll multiple console devices for input and send output to all devices registered for output. 5) include/common.h includes iomux.h and common/Makefile generates iomux.o when CONFIG_SYS_CONSOLE_MUX is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code.
