* nios2: Reload timer count in reset_timer()Scott McNutt2010-04-021-0/+33
| | | | | | | | | | | | | | | | | | | When the timestamp is incremented via interrupt and the interrupt period is greater than 1 msec, successive calls to get_timer() can produce inaccurate timing since the interrupts are asynchronous to the timing loop. For example, with an interrupt period of 10 msec two successive calls to get_timer() could indicate an elapsed time of 10 msec after only several hundred usecs -- depending on when the next interrupt actually occurs. This behavior can cause reliability issues with components such as CFI and NAND. This can be remedied by calling reset_timer() prior to establishing the base timestamp with get_timer(0), provided reset_timer() resets the hardware timer (rather than simply resetting only the timestamp). This has the effect of synchronizing the interrupts (and the advance of the timestamp) with the timing loop. Signed-off-by: Scott McNutt <smcnutt@psyent.com>
* nios2: Fix outx/writex parameter order in io.hScott McNutt2010-04-022-11/+11
| | | | | | | | | The outx/writex macros were using writex(addr, val) rather than the standard writex(val, addr), resulting in incompatibilty with architecture independent components. This change set uses standard parameter order. Signed-off-by: Scott McNutt <smcnutt@psyent.com>

* nios2: Move serial drivers to individual files in drivers/serialScott McNutt2010-04-022-310/+1
| | | | | | | | The standard Altera UART & JTAG UART as well as the OpenCores YANU driver are now in individual files in drivers/serial rather than a single file uner cpu/nios2. Signed-off-by: Scott McNutt <smcnutt@psyent.com>

* General help message cleanupWolfgang Denk2009-06-122-2/+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>
* Command usage cleanupPeter Tyser2009-01-281-1/+1
| | | | | | | | Remove command name from all command "usage" fields and update common/command.c to display "name - usage" instead of just "usage". Also remove newlines from command usage fields. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Update U-Boot's build timestamp on every compilePeter Tyser2008-12-061-1/+2
| | | | | | | Use the GNU 'date' command to auto-generate a new U-Boot timestamp on every compile. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* Big white-space cleanup.Wolfgang Denk2008-05-211-5/+5
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* cpu/[7a-ln-z]*: Remove obsolete references to CONFIG_COMMANDSJon Loeliger2007-07-091-2/+2

* cpu/ non-mpc*: Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).Jon Loeliger2007-07-041-1/+1
| | | | | | | | | | | | | | This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger <jdl@freescale.com>
* Move "ar" flags to config.mk to allow for silent "make -s"Wolfgang Denk2006-10-091-1/+1

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-011-10/+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.
* Nios II - Add EPCS Controller bootrom work-aroundScott McNutt2006-06-081-0/+15
| | | | | | | -When booting from an epcs controller, the epcs bootrom may leave the slave select in an asserted state causing soft reset hang. This patch ensures slave select is negated at reset. Patch by Scott McNutt, 08 Jun 2006
