* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

| * ppc4xx: TLB init file cleanupStefan Roese2010-04-19-56/+10
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>
* | Move arch/ppc to arch/powerpcStefan Roese2010-04-21-8/+8
|/ | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

* ppc: Enable full relocation to RAMPeter Tyser2009-10-03-2/+0
| | | | | | | | | | | | | The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

* ppc4xx: Convert PPC4xx UIC defines from lower case to upper caseStefan Roese2009-09-28-30/+30

* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-18/+18
| | | | | | | | | | | | | | | | This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
* General help message cleanupWolfgang Denk2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
* boards: move board_get_enetaddr() into board-specific initMike Frysinger2009-03-20-0/+29
| | | | | | | | | | | | The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Rather than have the common ppc code have board-specific hooks, move the board_get_enetaddr() function into the board-specific init functions.

* ppc4xx: Rework 440GX UIC handlingStefan Roese2008-07-11-19/+31
| | | | | | | | | | | | | This patch reworks the 440GX interrupt handling so that the common 4xx code can be used. The 440GX is an exception to all other 4xx variants by having the cascading interrupt vectors not on UIC0 but on a special UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt handling is simpler without any 440GX special cases. Also some additional cleanup to cpu/ppc4xx/interrupt.c is done. Signed-off-by: Stefan Roese <sr@denx.de>

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc4xx: Rework of 4xx serial driver (2)Stefan Roese2007-10-31-2/+2
| | | | | | | | | | Change all linker scripts to reference the changed driver name 4xx_uart.o. Note: In most cased all these explicit referencing of these object files in the linker scripts is not neccessary. Only for manually embedded environment into the U-Boot image, which is not done is most cases. Signed-off-by: Stefan Roese <sr@denx.de>

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-5/+14
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

* Changed PPC44x startup message (cpu info, speed...) to common style:Stefan Roese2005-11-27-6/+0
| | | | | | | | | | | On PPC44x platforms, the startup message generated in "cpu.c" only comprised the ppc type and revision but not additional informations like speed etc. Those speed infos where printed in the board specific code. This new implementation now prints all CPU infos in the common cpu specific code. No board specific code is needed anymore and therefore removed from all current 44x implementations.
