* Blackfin: bf518f-ezbrd: convert to portmux frameworkMike Frysinger2010-07-131-12/+6
| | | | | | | Rather than bang MMRs directly, use the new portmux framework to handle the details. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf518f-ezbrd: handle different PHYs dynamicallyMike Frysinger2010-07-132-10/+33
| | | | | | | | | The original BF518F-EZBRD's have a Micrel KSZ8893 DSA on them, but newer ones only have a National PHY (which lack a RX Error interrupt line). So in the board eth init code, dynamically detect what is hooked up to the MAC and handle each accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf533-stamp: scrub unused codeMike Frysinger2010-07-132-54/+9
| | | | | | | | Much of the local bf533-stamp.h header is unused, and the few bits that are are only needed in one file. So move the few used bits out and punt all the rest. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: bf537-stamp: use common spi boot workaround codeMike Frysinger2010-07-051-5/+2
| | | | | | | | The common gpio code provides a function for handling the spi boot workaround logic, so switch over to that rather than bang on the gpio MMRs directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: switch to common GPIO LED driverMike Frysinger2010-07-055-100/+10
| | | | | | | Now that we have a unified gpio layer, the different status led implementations can be switched to the common gpio led driver. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: back out status_led.h stubsMike Frysinger2010-07-053-15/+0
| | | | | | | | When boards define CONFIG_BOARD_SPECIFIC_LED, the common led definitions are OK for Blackfin boards. So switch the few boards using these over to the common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify custom gpio commandsMike Frysinger2010-07-0514-387/+127

* Blackfin: import gpio/portmux layer from LinuxMike Frysinger2010-07-0520-0/+3561
| | | | | | | | | The current pinmux handling has spread throughout Blackfin drivers and board code and is getting hideous to maintain. So import the gpio and portmux layer from the Blackfin Linux code. This should spur a serious of cleanups across the Blackfin tree. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: implement bootcount supportMike Frysinger2010-07-052-0/+35
| | | | | | | | The default storage location for bootcount is EVT0. This version uses one 32bit value and combines the magic/count value in the upper/lower 16bits. If there is demand for more, should be easy to do. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: clean up trace buffer handling when crashingMike Frysinger2010-07-052-28/+49
| | | | | | | | | | Avoid banging on the trace MMRs when debugging is disabled, avoid calling the funcs multiple times in a row, disable the trace buffer earlier in the exception handler to avoid eating more user entries, and dump the buffer before calling the kgdb hook. This way we maximize useful debugging info up front rather than needing external tools (like gdb/serial/etc...). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04295-670/+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) { ...

* Redundant environment: move flag definitions to header fileWolfgang Denk2010-07-043-8/+3

| * ppc4xx: Cleanup Boot/FLASH TLB reassignment for PPC440/460Stefan Roese2010-07-011-15/+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.

| | | | | | | | | | | | | | | | | | As described in item #10 of the SDRAM initialization (chapter 22.2.9 of the PPC460EX/EXr/GT users manual), RDSS may need to be adjusted. The code for this is now factored out and executed for non-SPD based boards as well. Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Enable overwriting of default scan window for IBM DDR2 controllerStefan Roese2010-07-012-12/+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 Roese2010-07-011-1/+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. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * | add redundant environment for env_sf.cWolfgang Wegner2010-06-301-0/+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.
