-Subject: [PATCH] ddr: marvell: a38x: fix SPLIT_OUT_MIX state decision
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This is a cleaned up and fixed version of a patch
- mv_ddr: a380: fix SPLIT_OUT_MIX state decision
-
- in each pattern cycle the bus state can be changed
- in order to avoide it, need to back to the same bus state on each
- pattern cycle
-by
- Moti Boskula <motib@marvell.com>
-
-The original patch is not in Marvell's mv-ddr-marvell repository. It was
-gives to us by Marvell to fix an issues with DDR training on some
-boards, but it cannot be applied as is to mv-ddr-marvell, because it is
-a very dirty draft patch that would certainly break other things, mainly
-DDR4 training code in mv-ddr-marvell, since it changes common functions.
-
-I have cleaned up the patch and removed stuff that seemed unnecessary
-(when removed, it still fixed things). Note that I don't understand
-completely what the code does exactly, since I haven't studied the DDR
-training code extensively (and I suspect that no one besides some few
-people in Marvell understand the code completely).
-
-Anyway after the cleanup the patch still fixes isssues with DDR training
-on the failing boards.
-
-There was also a problem with the original patch on some of the Allied
-Telesis' x530 boards, reported by Chris Packham. I have asked Chris to
-send me some logs, and managed to fix it:
-- if you look at the change, you'll notice that it introduces
- subtraction of cur_start_win[] and cur_end_win[] members, depending on
- a bit set in the current_byte_status variable
-- the original patch subtracted cur_start_win[] if either
- BYTE_SPLIT_OUT_MIX or BYTE_HOMOGENEOUS_SPLIT_OUT bits were set, but
- subtracted cur_end_win[] only if the first one (BYTE_SPLIT_OUT_MIX)
- was set
-- from Chris Packham logs I discovered that the x530 board where the
- original patch introduced DDR training failure, only the
- BYTE_HOMOGENEOUS_SPLIT_OUT bit was set, and on our boards where the
- patch is needed only the BYTE_SPLIT_OUT_MIX is set in the
- current_byte_status variable
-- this led me to the hypothesis that both cur_start_win[] and
- cur_end_win[] should be subtracted only if BYTE_SPLIT_OUT_MIX bit is
- set, the BYTE_HOMOGENEOUS_SPLIT_OUT bit shouldn't be considered at all
-- this hypothesis also gains credibility when considering the commit
- title ("fix SPLIT_OUT_MIX state decision")
-
-Hopefully this will fix things without breaking anything else.

-Subject: [PATCH] ddr: marvell: a38x: Fix Synchronous vs Asynchronous mode
- determination
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Before commit 4c289425752f ("mv_ddr: a38x: add support for ddr async
-mode"), Asynchornous Mode was only used when the CPU Subsystem Clock
-Options[4:0] field in the SAR1 register was set to value 0x13: CPU at
-2 GHz and DDR at 933 MHz.
-
-Then commit 4c289425752f ("mv_ddr: a38x: add support for ddr async
-mode") added support for Asynchornous Modes with frequencies other than
-933 MHz (but at least 467 MHz), but the code it added to check for
-whether Asynchornous Mode should be used is wrong: it checks whether the
-frequency setting in board DDR topology map is set to value other than
-MV_DDR_FREQ_SAR.
-
-Thus boards which define a specific value, greater than 400 MHz, for DDR
-frequency in their board topology (e.g. Turris Omnia defines
-MV_DDR_FREQ_800), are incorrectly put into Asynchornous Mode after that
-commit.
-
-The A38x Functional Specification, section 10.12 DRAM Clocking, says:
- In Synchornous mode, the DRAM and CPU clocks are edge aligned and run
- in 1:2 or 1:3 CPU to DRAM frequency ratios.
-
-Change the check for whether Asynchornous Mode should be used according
-to this explanation in Functional Specification.

-
-Use malloc_cache_aligned() to allocate this memory dynamically instead.

-Subject: [PATCH] mmc: xenon_sdhci: remove wait_dat0 SDHCI OP
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Generic SDHCI driver received support for checking the busy status by
-polling the DAT[0] level instead of waiting for the worst MMC switch time.
-
-Unfortunately, it appears that this does not work for Xenon controllers
-despite being a part of the standard SDHCI registers and the Armada 3720
-datasheet itself telling that BIT(20) is useful for detecting the DAT[0]
-busy signal.
-
-I have tried increasing the timeout value, but I have newer managed to
-catch DAT_LEVEL bits change from 0 at all.
-
-This issue appears to hit most if not all SoC-s supported by Xenon driver,
-at least A3720, A8040 and CN9130 have non working eMMC currently.
-
-So, until a better solution is found drop the wait_dat0 OP for Xenon.
-I was able to only test it on A3720, but it should work for others as well.

-Subject: [PATCH 1/3] ddr: marvell: a38x: fix BYTE_HOMOGENEOUS_SPLIT_OUT
- decision
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-In commit 3fc92a215b69 ("ddr: marvell: a38x: fix SPLIT_OUT_MIX state
-decision") I ported a cleaned up and changed version of patch
- mv_ddr: a380: fix SPLIT_OUT_MIX state decision
-
-In the port we removed checking for BYTE_HOMOGENEOUS_SPLIT_OUT bit,
-because:
-- the fix seemed to work without it
-- the bit was checked for only at one place out of two, while the second
- bit, BYTE_SPLIT_OUT_MIX, was checked for in both cases
-- without the removal it didn't work on Allied Telesis' x530 board
-
-We recently had a chance to test on more boards, and it seems that the
-change needs to be opposite: instead of removing the check for
-BYTE_HOMOGENEOUS_SPLIT_OUT from the first if() statement, the check
-needs to be added also to the second one - it needs to be at both
-places.
-
-With this change all the Turris Omnia boards I have had available to
-test seem to work, I didn't encounter not even one failed DDR training.
-
-As last time, I am noting that I do not understand what this code is
-actually doing, I haven't studied the DDR training algorithm and
-I suspect that no one will be able to explain it to U-Boot contributors,
-so we are left with this blind poking in the code with testing whether
-it works on several boards and hoping it doesn't break anything for
-anyone :-(.

-(If the DDR training fails while booting the image via UART, we will

-The state of the current DDR training code for Armada 38x is such that
-we cannot be sure it will always train successfully - although after the
-last change we were yet unable to find a board that failed DDR training,
-from experience in the last 2 years we know that it is possible.
-
-The experience also tells us that in many cases the board fails training
-only sometimes, and after a reset the training is successful.
-
-Enable the new option that makes the board reset itself on DDR training
-failure immediately. Until now we called hang() in such a case, which
-meant that the board was reset by the MCU after 120 seconds.
