ef6c26d338 rtc: pcf2127: Fixed bug with rtc settings and getting error time
The previous pcf2127 RTC chip could not read and set the correct time.
When reading the data of internal registers, the read address was the
value of register plus 1. This is because this chip requires the host
to send a stop signal after setting the register address and before
reading the register data.

This patch sets the register address using dm_i2c_write and reads
the register data using the original dm_i2c_xfer in order to generate
a stop signal after the register address is set, and fixes the bug of
the original read and write time.

4e829e9841 rtc: m41t62: add compatible for m41t82
This adds a compatible string for m41t82. This ensures that this driver
can be used for m41t82 in DM mode, too (asit was usable for this model in
non-DM mode before).

In addition, the HT bit has to be reset during probe, since the m41t82
chip sets it when entering battery standby mode.

This patch ensures this driver works on socfpga_socrates.

a73610d2c6 rtc: rv3029: update to support DM and sync with Linux 4.17
The "Flamingo" carrier-board for the RK3399-Q7 has a RV3029 populated
and the application will use the off-module RV3029 RTC including the
battery backed SRAM.

To support this use case, this commit includes the following changes:
 * updates the rv3029 driver to use DM
 * implements the read8/write8 operations

This syncs the implementation with the Linux code (based on 4.17),
porting the trickle-charger support from there (with improvements to
avoid unnecessary EEPROM updates) and adheres to the Linux DTS
binding.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

6087be2ba6 rtc: mc146818: Correct alarm message for day alarm
RTC_CONFIG_D register contains the day within the month to generate
an alarm, not the month. This corrects the printf to indicate it.

00caae6d47 env: Rename getenv/_f() to env_get()
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.

064b55cfcb powerpc, 5xxx, 512x: remove support for mpc5xxx and mpc512x
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.

5b8e76c35e powerpc, 8xx: remove support for 8xx
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).

2bd3cab335 rtc: ds1337: drop "SYS" from config variables
There is some inconsistency between uses of CONFIG_RTC_DS13xx and
CONFIG_SYS_RTC_DS13xx. Address this by dropping the "SYS" from
these variables.
