Upstream linux serial driver use a different logic to setup serial regs.
They have 2 interval:
- < 115200 we use lowspeed regs and 16 * baud
- >= 115200 we use highspeed
We currently use force_highspeed property to force usage of highspeed
regs even with low baud rate.

Add optional support for using old DDR3 training code from 2017.
The code lives in drivers/ddr/marvell/a38x/old/. To prevent symbol
clashing with new DDR3 training code, a special header which renames all
clashing symbols via macros is included and the symbols are prefixed
with 'old_'.
If old DDR3 training support is selected for a board, then the SPL
initialization code calls a new function
board_use_old_ddr3_training()
to check whether it should use old DDR3 training code. The default
weak implementation returns false, defaulting to new DDR3 training code.
Boards that wish to support this need to select the
ARMADA_38X_SUPPORT_OLD_DDR3_TRAINING
config option and implement the old version of DDR topology provider,
ddr3_get_topology_map().

Import DDR training code from commit 1b69ce2fc0 ("arm: mvebu:
ddr3_debug: remove self assignments") into
drivers/ddr/marvell/a38x/old/. The code is not used yet.
Explanation:
Since 2019, on some Turris Omnia boards we have been having problems
with newer versions of Marvell's DDR3 training code for Armada 38x,
which is ported from mv-ddr-marvell [1] to U-Boot into the
drivers/ddr/marvell/a38x/ directory:
- sometimes the DDR3 training fails on some older boards, sometime it
fails on some newer boards
- other times it succeeds, but some boards experience crashes of the
operating system after running for some time.
Using the stock version of Turris Omnia's U-Boot from solved these
issues, but this solution was not satisfactory, since we wanted
features from new U-Boot.
Back in 2020-2022 we have spent several months trying to debug the
issues, working with Marvell, on our own, and also with U-Boot
community, but these issues persist still.
One solution we used back in 2019 was a "hybrid U-Boot": the SPL part
(containing the DDR3 training code) was taken from the stock version,
while the proper part was current U-Boot at the time. This solution also
has its drawbacks, of which the main one is the need to glue binaries
from two separate builds.
Since then there have been some more changes to the DDR3 training code
in upstream mv-ddr-marvell that have been ported to U-Boot. We have
provided our users experimental builds of U-Boot in the TurrisOS so that
they could try upgrading the firmware and let us know if those problems
still exist. And they do.
We do not have the time nor manpower to debug this problem and fix it
properly. Marvell was also no able to provide a solution to this,
probably because they do not have the manpower as well.
I have therefore come up with this "not that pretty" solution: take the
DDR3 training code from an older version of U-Boot that is known to
work, put it into current U-Boot under old/ subdirectory within
drivers/ddr/marvell/a38x/, build into the SPL binary both the old and
new versions and make it possible to select the old version via an env
variable.

Return from ddr3_tip_print_log() early if we won't print anything

This way the compiler can optimize away the VALIDATE_IF_ACTIVE() calls
in the for-loop, so if the SILENT_LIB macro is defined, no code is
generated for the rest of the function, which saves some space.

Upstream Linux commit f90b68d6c8b0.
The CORE/BUS root slice has following design, simplied graph:
The difference is core not have pre_div block.
A composite core/bus clk has 8 inputs for mux to select, saying clk[0-7].
It support target(smart) interface and normal interface. Target interface
is exported for programmer easy to configure ccm root. Normal interface
is also exported, but we not use it in our driver, because it will
introduce more complexity compared with target interface.
The normal interface simplified as below:
SEL_A GA
+--+ +-+
| +->+ +------+
CLK[0-7]--->+ | +-+ |
| | | +----v---+ +----+
| +--+ |pre_diva+----> | +---------+
| +--------+ |mux +--+post_div |
| +--+ |pre_divb+--->+ | +---------+
| | | +----^---+ +----+
+--->+ | +-+ |
| +->+ +------+
+--+ +-+
SEL_B GB
The mux in the upper pic is not the target interface MUX, target
interface MUX is hiding SEL_A and SEL_B. When you choose clk[0-7],
you are actually writing SEL_A or SEL_B depends on the internal
counter which will also control the internal "mux".
The target interface simplified as below which is used by Linux Kernel:
CLK[0-7]--->MUX-->Gate-->pre_div-->post_div
A requirement of the Target Interface's software is that the
target clock source is active, it means when setting SEL_A, the
current input clk to SEL_A must be active, same to SEL_B.
We touch target interface, but hardware logic actually also need
configure normal interface.
There will be system hang, when doing the following steps:
The initial state:
SEL_A/SEL_B are both sourcing from clk0, the internal counter
choose SEL_A.
1. switch mux from clk0 to clk1
The hardware logic will choose SEL_B and configure SEL_B to clk1.
SEL_A no changed.
2. gate off clk0
Disable clk0, then the input to SEL_A is off.
3. switch from clk1 to clk2
The hardware logic will choose SEL_A and configure SEL_A to clk2,
however the current SEL_A input clk0 is off, the system hang.
The solution to fix the issue is in step 1, write twice to
target interface MUX, it will make SEL_A/SEL_B both sources
from clk1, then no need to care about the state of clk0. And
finally system performs well.

Timer value is a 16 bits calculated from the wanted timeout and the
system clock. On powerpc/8xx, a timeout of 2s gives a value which
is over U16_MAX so U16_MAX shall be used. But the calculation is
casted to u16 so at the end the result is 63770 instead of 128906.
So the timer gets loaded with 63770 instead of 65535. It is not
a big difference in that case, but lets make the code correct and
cast to u32 instead of u16.
