2018-07-30Merge tag 'signed-efi-next' of git://github.com/agraf/u-bootTom Rini
Patch queue for efi - 2018-07-25 Highlights this time: - Many small fixes to improve spec compatibility (found by SCT) - Almost enough to run with sandbox target - GetTime() improvements - Enable EFI_LOADER and HYP entry on ARMv7 with NONSEC=y
2018-07-28drivers: rtc: correctly set week day for mc146818Heinrich Schuchardt
The driver sets the weekday incorrectly when called by the 'date set' command. Sunday is 1, Saturday is 7 unlike in U-Boot (see data sheet https://www.nxp.com/docs/en/data-sheet/MC146818.pdf, table 3). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2018-07-25rtc: remove CONFIG_CMD_DATE dependencyHeinrich Schuchardt
The EFI subsystem accesses the real time clock and is enabled by default. So we should drop any CONFIG_CMD_DATE dependency from the real time clock drivers. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-07-20drivers: rtc: correct week day for mc146818Heinrich Schuchardt
For qemu-x86 the date command produces wrong days of the week: Date: 2018-07-06 (Saturday) Time: 18:02:03 Date: 2018-07-07 (unknown day) Time: 21:02:06 According to a comment in the Linux driver the mc146818 only updates the day of the week if the register value is non-zero. Sunday is 1, saturday is 7 unlike in U-Boot (see data sheet https://www.nxp.com/docs/en/data-sheet/MC146818.pdf). So let's use our library function to determine the day of the week.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

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>
2016-10-11rtc: Use CONFIG_X86 instead of __I386__Simon Glass
For 64-bit x86, __I386__ should perhaps not be defined. It is not clear from the definition, but let's use CONFIG_X86 to be sure. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

The AmigaOneG3SE board has been orphaned or a very long time, and broken for more than 12 releases resp. more than 3 years. As nobody seems to be interested any more in this stuff we may as well ged rid of it, especially as it clutters many areas of the code so it is a continuous pain for all kinds of ongoing work.

2008-03-20LWMON5: POST RTC fixYuri Tikhonov
Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature. Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
