* rtc: adding RX8010SJ rtc driverNandor Han2018-02-043-0/+385
| | | | | | | | | Add a new driver for RX8010SJ rtc chip. The driver implements both formats of U-Boot driver model. Signed-off-by: Nandor Han <nandor.han@ge.com> Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>

* rtc: mc146818: Correct alarm message for day alarmBin Meng2017-10-231-1/+1
| | | | | | | RTC_CONFIG_D register contains the day within the month to generate an alarm, not the month. This corrects the printf to indicate it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
* env: Rename getenv/_f() to env_get()Simon Glass2017-08-161-1/+1
| | | | | | | | | | | We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

* powerpc, 5xxx, 512x: remove support for mpc5xxx and mpc512xHeiko Schocher2017-06-162-129/+0
| | | | | | | | | There was for long time no activity in the mpx5xxx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in mpc5xxx, so remove it. Signed-off-by: Heiko Schocher <hs@denx.de>
* powerpc, 8xx: remove support for 8xxHeiko Schocher2017-06-122-61/+0
| | | | | | | | | | There was for long time no activity in the 8xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 8xx, so remove it (with a heavy heart, knowing that I remove here the root of U-Boot). Signed-off-by: Heiko Schocher <hs@denx.de>

The clock works off an offset from the current system time, and supports setting and getting the clock, as well as access to byte-width regisers in the RTC.

This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

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
