* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* examples/standalone: Remove relocation compile flags for PowerPCPeter Tyser2010-06-29-0/+10
| | | | | | | | | | | | | | | | | | | | Previously, standalone applications were compiled with gcc flags that produced relocatable executables on the PowerPC architecture (eg with the -mrelocatable and -fPIC flags). There's no reason for these applications to be fully relocatable at this time since no relocation fixups are performed on standalone applications. Additionally, removing the gcc relocation flags results in the entry point of applications residing at the base of the image. When a standalone application was relocatable, the entry point was generally located at an offset into the image which was confusing and prone to errors. This change moves the entry point of PowerPC standalone applications from 0x40004 (usually) to 0x40000. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>

* nios2: fix r15 issue for gcc4Thomas Chou2010-05-28-3/+3
| | | | | | | | | | The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Scott McNutt <smcnutt@psyent.com>
* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-2/+2
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | Commit 6a45e384955262882375a2785426dc65aeb636c4 (Make getenv_IPaddr() global) inadvertently added ' #include "net.h" ' to the standalone programs, creating duplicate definitions of 'struct eth_device'. This patch removes the local definitions and removes other code that breaks due to the change in definition.

* Fix build failure in examples/standaloneSanjeev Premi2009-12-02-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some versions of 'make' do not handle trailing white-spaces properly. Trailing spaces in ELF causes a 'fake' source to be added to the variable COBJS; leading to build failure (listed below). The problem was found with GNU Make 3.80.

* atmel_df_pow2: standalone to convert dataflashes to pow2Mike Frysinger2009-09-04-0/+214
| | | | | | | | | | | | Atmel DataFlashes by default operate with pages that are slightly bigger than normal binary sizes (i.e. many are 1056 byte pages rather than 1024 bytes). However, they also have a "power of 2" mode where the pages show up with the normal binary size. The latter mode is required in order to boot with a Blackfin processor, so many people wish to convert their DataFlashes on their development systems to this mode. This standalone application does just that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* 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...

* Fix examples for OMAP3 boards...Michael Evans2009-08-08-1/+1
| | | | | | | | | | | | | | | | | | The attached patch corrects an error in the examples/Makefile which causes the applications in the examples directory to hang on OMAP3 based boards. The current Makefile sets -Ttext during linking to 0x0c100000 which is outside of addressable SDRAM memory. The script corrects the existing ifeq...else...endif logic to look at the VENDOR tag rather than the CPU tag. The patch affects the following configs: omap3_beagle_config, omap3_overo_config, omap3_evm_config, omap3_pandora_config, omap3_zoom1_config and omap3_zoom2_config.
