* imx_watchdog: always set minimal timeout in reset_cpuAndrey Skvortsov2016-01-07-1/+1
| | | | | | | | | The problem is that timeout bits in WCR register were leaved unchanged. So previously set timeout value was applied and therefore 'reset' command takes any value up to two minutes, depending on previous watchdog settings, instead of minimal 0.5 seconds.

* ls102xa: Fix reset hangFabio Estevam2015-10-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Since commit 623d96e89aca6("imx: wdog: correct wcr register settings") issuing a 'reset' command causes the system to hang. Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian. This means that the watchdog on LS1021 has been working by accident as it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c. Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only revelead the endianness problem on LS102x. In order to fix the reset hang, introduce a reset_cpu() implementation that is specific for ls102x, which accesses the watchdog WCR register in big-endian format. All that is required to reset LS102x is to clear the SRS bit. This approach is a temporary workaround to avoid a regression for LS102x in the 2015.10 release. The proper fix is to make the watchdog driver endian-aware, so that it can work for i.MX, Vybrid and LS102x.

* imx: wdog: correct wcr register settingsPeng Fan2015-09-20-1/+2
| | | | | | | | | | | | | We should not simple use "writew(WCR_WDE, &wdog->wcr)" to set wcr, since this will override bits set before reset_cpu. Use clrsetbits_le16 instead of writew to fix this issue.

* watchdog/imx_watchdog: do not set WCR_WDWSebastian Siewior2015-03-25-2/+1
| | | | | | | | | | | | | | with WCR_WDW set, the watchdog won't trigger if we bootet linux and idle around while the watchdog is not triggered. It seems the timer makes progress very slowly if at all. I managed to remain 20minutes alive while the timeout was set to 60secs. It reboots within 60secs if I start a busyloop in userland (something like "while (1) { }"). While I don't see a reason why the WDT should not be running while the CPU is in idle, I'm dropping this bit.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
