drivers: rtc: correctly set week day for mc146818

2018-07-28T15:58:09+00:00

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).

rtc: remove CONFIG_CMD_DATE dependency

2018-07-25T13:00:24+00:00

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.

rtc: compile date.c if DM_RTC

2018-07-24T13:25:23+00:00

rtc_to_tm() and rtc_mktime() are required for some RTC drivers, at least
PL031. Without this patch, we also need to enable CONFIG_CMD_DATE even if
we don't want or need this command.

drivers: rtc: correct week day for mc146818

2018-07-20T19:55:04+00:00

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.

drivers: rtc: resolve year 2038 problem in rtc_to_tm

2018-07-19T21:03:36+00:00

Our implementation of rtc_to_tm() cannot handle dates of more than
0x7fffffff seconds after 1970-01-01.

Adopt the Linux kernel implementation.

ARM: qemu-arm: enable RTC

2018-07-19T20:31:37+00:00

QEMU provides an emulated ARM AMBA PrimeCell PL031 RTC.

The patch sets the base address in the board include file according to the
definition in hw/arm/virt.c of the QEMU source. It defines the Kconfig
option for the existing driver, and enables the RTC driver in
qemu_arm64_defconfig and qemu_arm_defconfig as well as the date command.

We need an RTC to provide the GetTime() runtime service in the UEFI
subsystem.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.
