According to DDRPHY errata, the Rank-to-Rank Spacing and tphy_rdcsgap
specification does not include the Critical Delay Difference (CDD) to
properly define the required rank-to-rank read command spacing after
executing PHY training firmware.
Following the errata workaround, at the end of data training, we get
all CDD values through the MessageBlock, then re-configure the DDRC
timing of WWT/WRT/RRT/RWT with comparing MAX CDD values.

- DDR Training sequence happens very fast. The speedup in boot time is
negligible by skipping the training sequence during 2nd boot or after.
So remove the check and skip.
- This change improves the robustness of DDR training. If u-boot crashed
during DDR training, the training could be left in a limbo state, where
the BootROM has recorded that it is already in a 2nd boot. The training
must be repeated in this scenario to get out of this limbo state, but due
to the check it cannot be performed.

This syncs drivers/ddr/marvell/a38x/ with the master branch of repository
https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git
up to the commit "mv_ddr: a3700: Use the right size for memset to not overflow"
d5acc10c287e40cc2feeb28710b92e45c93c702c
This patch was created by following steps:
1. Replace all a38x files in U-Boot tree by files from upstream github
Marvell mv-ddr-marvell repository.
2. Run following command to omit portions not relevant for a38x, ddr3, and ddr4:
files=drivers/ddr/marvell/a38x/*
unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_APN806 \
-UCONFIG_MC_STATIC -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
-UCONFIG_PHY_STATIC_PRINT -UCONFIG_CUSTOMER_BOARD_SUPPORT \
-UCONFIG_A3700 -UA3900 -UA80X0 -UA70X0 -DCONFIG_ARMADA_38X -UCONFIG_ARMADA_39X \
-UCONFIG_64BIT $files
3. Manually change license to SPDX-License-Identifier
(upstream license in upstream github repository contains long license
texts and U-Boot is using just SPDX-License-Identifier.
After applying this patch, a38x, ddr3, and ddr4 code in upstream Marvell github
repository and in U-Boot would be fully identical. So in future applying
above steps could be used to sync code again.
The only change in this patch are:
1. Some fixes with include files.
2. Some function return and basic type defines changes in
mv_ddr_plat.c (to correct Marvell bug).
3. Remove of dead code in newly copied files (as a result of the
filter script stripping out everything other than a38x, dd3, and ddr4).

Commit 290ffe5788 (imx8m: fix reading of DDR4 MR registers) lifted a
private definition of lpddr4_mr_read() from imx8mm-cl-iot-gate board
code to drivers/ddr/imx/imx8m/ddrphy_utils.c, because that version
actually seems to work in practice.
However, commit 99c7cc58e1 (ddr: imx: Add i.MX9 DDR controller driver)
reintroduced the broken version in drivers/ddr/imx/imx8m/ddr_init.c,
copied most of the rest of ddrphy_utils.c to
drivers/ddr/imx/phy/ddrphy_utils.c, and stopped building
drivers/ddr/imx/imx8m/ddrphy_utils.c [and that file was then finally
completely removed with 7e9bd84883 (imx8m: ddrphy_utils: Remove unused
file)].
I assume this must have broken the imx8mm-cl-iot-gate board, at least
those that have not had their eeprom programmed with the proper
information. It certainly did break our out-of-tree board which always
reads back the ID register and uses that for a sanity check.
So apply the fix from 290ffe5788 once again.

U-Boot core code already handles the case when RAM size is bigger than
CONFIG_MAX_MEM_MAPPED. So there is no need to do duplicate check in fsl ddr
driver for CONFIG_MAX_MEM_MAPPED. Instead simplify code to just check if
RAM size can be representable in phys_size_t type. And avoid printing
warning if phys_size_t is just 1 byte smaller than RAM size, which is the
typical situation with 4 GB DDR module.

Function fsl_ddr_compute() always return size in unsigned long long type,
but function fsl_ddr_sdram_size() returns size in phys_size_t type.
When 36-bit addressing mode is not enabled then phys_size_t type is only
32-bit and thus it cannot store value 4GB (0x100000000). Function
fsl_ddr_sdram_size() in this case returns truncated value 0x0.
Fix this issue by returning the highest representable value, which is
0xffffffff (4GB - 1 byte).
This change fixes crashing of proper U-Boot because it detected 4 GB module
as RAM with zero size.

In both the Freescale DDR controller and the SPD spec, bank address bits
are stored as the number of bank address bits minus 2. For example, if a
chip had 8 banks (3 total bank address bits), the value of
bank_addr_bits would be 1. This is rather surprising for users
configuring their memory manually, since they can't set bank_addr_bits
to the actual number of bank address bits. Rectify this.
There is at least one example of this kind of mistake already, in
board/freescale/t102xrdb/ddr.c. The documented MT40A512M8HX has two bank
address bits, but bank_addr_bits was set to 2, implying 4 bank address
bits. Such a value is reserved in BA_BITS_CS, but I suspect the
controller simply ignores the top bit, making this kind of mistake
harmless, if misleading.

The interactive mode uses large several tables of options which can be
configured. However, much of the contents of these tables are
repetetive. For example, no struct is larger than half a kilobyte, so
the offset only takes up 9 bits. Similarly, the size is only ever 4 or
8, and printhex is a boolean. Reduce the size of these fields. This
reduces the size of the options tables by around 10 KiB. However, the
largest contributor to the size of the options tables is the use of a
pointer for the strings. A better approach would be to use a separate
array of strings, and store an integer index in the options tables.
However, this would require a large re-architecting of this file.

I was trying to employ lpddr4_mr_read() to something similar to what
the imx8mm-cl-iot-gate board is doing for auto-detecting the RAM
type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c
differs from the private one used by that board in how it extracts the
byte value, and I was only getting zeroes. Adding a bit of debug
printf'ing gives me
tmp = 0x00ffff00
tmp = 0x00070700
tmp = 0x00000000
tmp = 0x00101000
and indeed I was expecting a (combined) value of 0xff070010 (0xff
being Manufacturer ID for Micron). I can't find any documentation that
says how the values are supposed to be read, but clearly the iot-gate
definition is the right one, both for its use case as well as my
imx8mp-based board.
So lift the private definition of lpddr4_mr_read() from the
imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration
in the ddr.h header where e.g. get_trained_CDD() is already declared.
This has only been compile-tested for the imx8mm-cl-iot-gate
board (since I don't have the hardware), but since I've merely moved
its definition of lpddr4_mr_read(), I'd be surprised if it changed
anything for that board.
