2013-11-11time: fix gcc warnings on MIPS64Daniel Schwierzeck
Commit 8dfafdde88eb3e71d5569846396ae67a91017232 introduced new gcc warnings on MIPS64: time.c: In function 'tick_to_time': time.c:59:2: warning: comparison of distinct pointer types lacks a cast [enabled by default] time.c:59:2: warning: passing argument 1 of '__div64_32' from incompatible pointer type [enabled by default] In file included from time.c:10:0: ./u-boot-mips/include/div64.h:22:17: note: expected 'uint64_t *' but argument is of type 'long long unsigned int *' time.c: In function 'usec_to_tick': time.c:76:2: warning: comparison of distinct pointer types lacks a cast [enabled by default] time.c:76:2: warning: passing argument 1 of '__div64_32' from incompatible pointer type [enabled by default] In file included from time.c:10:0: ./u-boot-mips/include/div64.h:22:17: note: expected 'uint64_t *' but argument is of type 'long long unsigned int *' Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2013-11-08time: add weak annotation to timer_read_counter declarationRob Herring
A weak annotation is needed in order to prevent link errors when get_ticks is overridden. This fixes sandbox build. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2013-11-04Introduce common timer functionsRob Herring
Many platforms duplicate pretty much the same timer code yet they all have a 32-bit freerunning counter register. Create a common implementation that minimally requires 2 or 3 defines to add timer support: CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down All functions are weak or ifdef'ed so they can still be overriden by any platform.

2013-11-04config: consolidate CONFIG_SYS_HZ definitionRob Herring
According to the README, CONFIG_SYS_HZ must be 1000 and most platforms follow that. In preparation to remove CONFIG_SYS_HZ from all these platforms, provide a common definition. The platforms which use a value other than 1000 will get build warning now. These configs are: include/configs/M5271EVB.h:#define CONFIG_SYS_HZ 1000000 include/configs/balloon3.h:#define CONFIG_SYS_HZ 3250000 /* Timer @ 3250000 Hz */ include/configs/idmr.h:#define CONFIG_SYS_HZ (50000000 / 64) include/configs/mini2440.h:#define CONFIG_SYS_HZ 1562500 include/configs/mx1ads.h:#define CONFIG_SYS_HZ 3686400 include/configs/omap3_zoom2.h:#define CONFIG_SYS_HZ ((V_SCLK) / (2 << CONFIG_SYS_PTV)) include/configs/omap730p2.h:#define CONFIG_SYS_HZ ((CONFIG_SYS_CLK_FREQ)/(2 << CONFIG_SYS_PTV)) include/configs/palmld.h:#define CONFIG_SYS_HZ 3250000 /* Timer @ 3250000 Hz */ include/configs/palmtc.h:#define CONFIG_SYS_HZ 3686400 /* Timer @ 3686400 Hz */ include/configs/rsk7203.h:#define CONFIG_SYS_HZ (CONFIG_SYS_CLK_FREQ / CMT_CLK_DIVIDER) include/configs/rsk7264.h:#define CONFIG_SYS_HZ (CONFIG_SYS_CLK_FREQ / CMT_CLK_DIVIDER) include/configs/rsk7269.h:#define CONFIG_SYS_HZ (CONFIG_SYS_CLK_FREQ / CMT_CLK_DIVIDER) include/configs/scb9328.h:#define CONFIG_SYS_HZ 3686400 /* incrementer freq: 3.6864 MHz */ include/configs/versatile.h:#define CONFIG_SYS_HZ (1000000 / 256) include/configs/zipitz2.h:#define CONFIG_SYS_HZ 3250000 /* Timer @ 3250000 Hz */ Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2012-04-10Move bootstage timer out of lib/time.cSimon Glass
The standalone example does not have get_timer() defined, so we cannot rely on it being available. Move the timer function into boootstage.c to avoid this problem. This corrects a build breakage for the standalone example on some boards. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Matthias Fuchs <matthias.fuchs@esd.eu>
2012-03-18bootstage: Define an optional microsecond timerSimon Glass
Define timer_get_boot_us() which returns the number of microseconds since boot. If undefined then we use get_timer() * 1000. We can fit this in a 32-bit register which keeps everyone happy on the efficiency side. It will wrap around after about an hour. If we are still looking at it after an hour then we had better not be timing the boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2011-10-21consolidate mdelay by providing a common function for all usersAnatolij Gustschin
There are several mdelay() definitions in the driver and board code. Remove them all and provide a common mdelay() in lib/time.c. Signed-off-by: Anatolij Gustschin <agust@denx.de> Acked-by: Mike Frysinger <vapier@gentoo.org>
2010-04-13Rename lib_generic/ to lib/Peter Tyser
Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
