rtc: Allow use of RTC in SPL and TPL

2018-10-09T10:40:27+00:00

Add Kconfig options so that the RTC can be used in SPL and TPL. This is
helpful for accessing the contents of CMOS RAM, for example.

Kconfig: Convert CONFIG_RTC_MC146818 to Kconfig

2018-10-09T10:40:27+00:00

Move this option to Kconfig and tidy up the two boards which use it.

rtc: Add read8 and write8 support to isl1208 driver

2018-10-08T18:45:02+00:00

This can be used for device register access from board code.

This allows access to capabilities in the RTC chip not abstracted in
U-Boot's RTC class.  E.g., device NVRAM or a tamper detection circuit.

rtc: pl031: convert the driver to driver model

2018-09-23T19:55:31+00:00

With this patch, PL031 driver is converted to driver-model-compliant
driver. In addition, CONFIG_SYS_RTC_PL031_BASE is no longer valid.

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

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.
