* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-670/+671
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Cleanup Boot/FLASH TLB reassignment for PPC440/460Stefan Roese2010-07-01-15/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background Info: Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via init.S) to speed up the boot process. In relocate_code (start.S) the cache inhibit attribute for this TLB is set to disable cache. This is needed for the CFI FLASH driver. This patch now cleans this code up: - CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not defined in the top of this file. This way, we can remove an ugly #ifdef in this code. - Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..." statement with "#if defined(CONFIG_440)". - Remove unnecessary cache invalidate calls resulting in faster bootup.

| * ppc4xx: Enable overwriting of default scan window for IBM DDR2 controllerStefan Roese2010-07-01-12/+10
| | | | | | | | | | | | | | | | | | | | | | This patch makes it possible to overwrite the default auto-calibration scan window (SDRAM_WRDTR.[WDTR], SDRAM_CLKTR.[CKTR] values) with board specific values. The parameters of the weak default function are corrected as well. This way we don't need the casts any more. This feature will be used by an upcoming PPC460GT board port.

| * ppc4xx: Enable PCIe support without PCI support on PPC440/460Stefan Roese2010-07-01-1/+11
| | | | | | | | | | | | | | | | | | | | | | By not defining CONFIG_SYS_PCI_MASTER_INIT and CONFIG_SYS_PCI_TARGET_INIT, PCI support (host and adapter) will not be enabled. But it's still possible to use the U-Boot PCI infrastructure for the PCIe ports. This configuration option is needed for a new 460GT board, which uses PCIe but has PCI disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message.

| * | add redundant environment for env_sf.cWolfgang Wegner2010-06-30-0/+232
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds redundant environment for environment in SPI flash. I took env_flash.c as an example and slightly modified it. Apart from adapting things to SF, I also slightly changed the decision logic to use area 2 as a default in case the flags are wrong because not having a default path worried me. I did not add a section for CONFIG_ENV_IS_IN_SPI_FLASH in environment.h because I did not understand if this is desired and/or needed. So to use the feature, one has to set CONFIG_ENV_OFFSET_REDUND _and_ CONFIG_SYS_REDUNDAND_ENVIRONMENT. I checked it by powering off my board several times during flash erase or write, because I do not know if there are other stress test scenarios.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

The parsing code looks for comma as a stopch, but there may be two kind of stop characters: a comma and a semicolon. Currently the code would return "value2;key2:value3", while just "value2" is the correct answer. This patch fixes the issue by making the code aware of multiple stop characters. For old U-Boots, the issue can be workarounded by placing a comma before a semicolon, i.e.: hwconfig=key1:subkey1=value1,subkey2=value2,;key2:value3 Reported-by: York Sun <yorksun@freescale.com> Signed-off-by: Anton Vorontsov <avorontsov@mvista.com>

State can not change during the copy loop, so it is possible to move these evaluations to before the copy loop. Cost is more code space as loop variants are required for each set of possible configurations. The loops are simpler however, so the extra is only 128bytes on da830 with CONFIG_SPI_HALF_DUPLEX defined. Unrolling the first copy loop iteration allows the TX buffer to be pre-loaded reducing SPI clock starvation. Unrolling the last copy loop iteration removes testing for the final loop iteration every time round the loop. Using the RX buffer empty flag as a transfer throttle allows the assumption that it is always safe to write to the TX buffer, so polling of TX buffer full flag can be removed.
