Simon Glass <sjg@chromium.org> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.
Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.
Update the comment in bootstage to refer to this symbol, instead of
SPL_

This adds support for reading the battery-backed memory present on these
RTCs. This modifies the read/write methods to access the RAM instead of
raw register offsets. No one was using these in-tree, so we should be
fine changing them.
We use the "standard" address space window to access the RAM. The
extension RAM address register has some reserved bits, but we write the
whole thing for simplicity (as these bits default to 0).

Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>
The DS1307 driver was originally based on the DS1337 driver. However,
the functionality of the clock set/get functions has diverged. In the
original DS1337 driver, the set/get functions did the following:
1) Setting the clock ensured the oscillator was enabled.
2) Getting the clock checked and reset the oscillator-stop flag.
The DS1307 does not have an oscillator-stop flag, but the driver tried
(incorrectly) to emulate this by ensuring the oscillator was running. It
really makes no sense to start a stopped clock without setting it.
This patch makes the DS1307 driver behave like the original DS1337
driver again. For the DS1307 itself, this is just a removal of code,
since there is no oscillator-fail bit to check or reset, and the clock
is started when it is set. Since the DS1307 driver can now also be used
for the DS1337 and DS1340 which do have this bit, add code to handle the
oscillator-stop bit in the same was the original DS1337 driver did --
i.e. report that the oscillator had stopped and clear the flag.
This means that setting the date using the date command (which does both
a get and a set) will now clear the oscillator-stop flag in addition to
setting and starting the clock.
The old-style (non-DM) code has not been updated and will be removed in
a future patch. Note that this older code does not support the DS1337,
as there is a separate driver for this. Also note that the original (DM)
code used the wrong control-register address for the DS1337.

From the note at the top of the file, it appears
target-dependent workarounds have been used in the

Resolve this by setting the time registers in a single

As part of this, also ensure the '24/12' flag in the RTC
is reset before writing the date (instead of after), otherwise
the RX8035 will clear the seconds and minutes registers.

The ds1307 driver also supports the DS1339 and DS1340.
However, in ds1307_rtc_reset the register writes assume that the chip
is a DS1307. This is evident in the writing of bits SQWE, RS1, RS0 to
the control register. While this applies correctly to the DS1307, on a
DS1340 the control register doesn't contain those bits (instead, the
register is used for clock calibration). By writing these bits the
clock calibration will be changed and the chip can become
non-functional after a reset call.
