351a4aa050 mmc: omap_hsmmc: Workaround errata regarding SDR104/HS200 tuning failures (i929)
Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions
(SPRZ426D - November 2014 - Revised February 2018 [1]) mentions
unexpected tuning pattern errors. A small failure band may be present
in the tuning range which may be missed by the current algorithm.
Furthermore, the failure bands vary with temperature leading to
different optimum tuning values for different temperatures.

As suggested in the related Application Report (SPRACA9B - October 2017
- Revised July 2018 [2]), tuning should be done in two stages.
In stage 1, assign the optimum ratio in the maximum pass window for the
current temperature. In stage 2, if the chosen value is close to the
small failure band, move away from it in the appropriate direction.

4233698dd3 mmc: sunxi: Honour non-removable property in DT
If a board DT describes a cd-gpios property, but also marks the storage
as non-removable, we must ignore the GPIO (as Linux does).

Teach the DM_MMC part of the Allwinner MMC driver about the
non-removable DT property, to fix DM_MMC access on the SoPine and
Pine64-LTS board.

Now that we have the gate clocks and the reset gates in our new
Allwinner clock driver, let's make use of them in the MMC driver, when
DM_MMC is defined.
We treat the reset device as optional now, as the older SoCs don't

The code is checking for incomplete read when it see the INT_XFER_COMPL
flag, but it forget to first check whether there is anything left in the
FIFO to copy to the RX buffer. This means that sometimes we will get
errors because of erroneous incomplete read operation.

This commit fixes the driver re-ordering the code so that we first
check for data inside the RX fifo and only after check the status
of the INT_XFER_COMPL flag.

2acc24fc28 Kconfig: Migrate BOUNCE_BUFFER
The bounce buffer is used by a few drivers (most of the MMC drivers)
to overcome limitations in their respective DMA implementation.

This moves the configuration to Kconfig and makes it user-selectable
(even though it will be a required feature to make those drivers
work): the expected usage is for drivers depending on this to 'select'
it unconditionally from their respective Kconfig (see follow-up
patches).

This commit includes a full migration using moveconfig.py to ensure
that each commit compiles.  To ensure bisectability we update
dependencies of various drivers to now select BOUNCE_BUFFER when needed.

82d5464788 mmc: jz_mmc: Compile-out write support if disabled
Do not build write support, unless it's enabled.

In the SPL case, this change will typically remove
precious bytes (as write support is most often
not needed in SPL).

This is important on this platform, where the maximum
SPL size is 14 KiB.

With gcc v7.3, this change saves 144 bytes producing:

size spl/u-boot-spl
   text	   data	    bss	    dec	    hex	filename
   9240	    752	    712	  10704	   29d0	spl/u-boot-spl

To make the code easier to compile-out and more
readable, a pair of read_data/write_data helpers are created.

b9a2a0e2e9 mmc: Add support for downgrading HS200/HS400 to HS mode
The mmc_select_mode_and_width() function can be called while the card
is in HS200/HS400 mode and can be used to downgrade the card to lower
mode, e.g. HS. This is used for example by mmc_boot_part_access_chk()
which cannot access the card in HS200/HS400 mode and which is in turn
called by saveenv if env is in the MMC.

In such case, forcing the card clock to legacy frequency cannot work.
Instead, the card must be switched to HS mode first, from which it can
then be reprogrammed as needed.

However, this procedure needs additional code changes, since the current
implementation checks whether the card correctly switched to HS mode in
mmc_set_card_speed(). The check only expects that the card will be going
to HS mode from lower modes, not from higher modes, hence add a parameter
which indicates that the HS200/HS400 to HS downgrade is happening. This
makes the code send the switch command first, reconfigure the controller
next and finally perform the EXT_CSD readback check. The last two steps
cannot be done in reverse order as the card is already in HS mode when
the clock are being switched on the controller side.

eef05fd3ba mmc: bring back partition init for non-DM MMC drivers
Commit d0851c8937 ("blk: Call part_init() in the post_probe() method")
removed the call to part_init() in mmc.c, as this is done by the DM_MMC
framework.
However Allwinner is (still) relying on a non-DM MMC driver, so we are
now missing the implicit partition init, leading to failing MMC accesses
due to the missing partition information.

Bring the call back just for non-DM MMC driver to fix this regression.

a740ee913e lib: merge CRC16-CCITT into u-boot/crc.h
This merges the CRC16-CCITT headers into u-boot/crc.h to prepare for
rolling CRC16 into the hash infrastructure.  Given that CRC8, CRC32
and CRC32-C already have their prototypes in a single header file, it
seems a good idea to also include CRC16-CCITT in the same.

cf345760bd mmc: Do not issue CMD 6 on SD 1.00 and SD 1.01
According to SD Specifications Part 1 Physical Layer Simplified Specification
Version 6.00 August 29, 2018, section 4.3.10 (Switch Function Command) and
section 5.6 (SCR register), SD cards version 1.00 and 1.01 do not support the
SD CMD 6.

Currently, U-Boot will issue CMD 6 unconditionally in sd_set_card_speed()
while configuring the bus for selected frequency. This will make SD cards
version 1.00 and 1.01 time out and thus fail detection altogether.

Fix this by not sending CMD 6 on such cards. Tested on Matsushita Electric
Industrial Co., Ltd. Japan RP-SD008B / Victor 8MB SD card, CU-SD008, which
is correctly detected with this patch as:

Device: sd@ee160000
Manufacturer ID: 1
OEM: 5041
Name: S008B
Bus Speed: 25000000
Mode : SD Legacy
Rd Block Len: 512
SD version 1.0
High Capacity: No
Capacity: 6.5 MiB

ed427dab2e mmc: tmio: Reorder TMIO clock handling
Reorder the tmio_sd_set_clk_rate() function such that it handles all
of the clock requiests correctly. Specifically, before this patch,
clock request with (mmc->clock == 0 && mmc->clk_disable) could leave
the clock enabled, as the function would exit on if (!mmc->clock)
condition on top and will not handle the mmc->clk_disable at all.

Rather than band-aid fixing just that particular problem, reorder
the entire function to make it easier to understand and verify that
all the cases are covered. The function has three sections now:

First, if mmc->clock != 0, we calculate divider for the SD block.
Second, if mmc->clock != 0 and SD block clock are enabled and
           current divider is not equal to the new divider, then
           stop the clock and update the divider.
Third, if mmc->clk_disable is set, disable the clock, otherwise
       enable the clock. This happens independently of divider
       update now.

59d529afdc mmc: tmio: Keep generating clock when clock are enabled
The TMIO core has a feature where it can automatically disable clock output
when the bus is not in use. While this is useful, it also interferes with
switching the bus to 1.8V and other background tasks of the SD/MMC cards,
which require clock to be enabled.

This patch respects the mmc->clk_disable and only disables the clock when
the MMC core requests it. Otherwise the clock are continuously generated
on the bus.

629d267a97 sunxi-mmc: don't double clock for new mode unconditionally
Comment in Linux driver says that clock needs to be doubled only
if we use DDR modes, moreover divider has to be set accordingly.

U-boot driver doesn't declare support for any DDR modes and doesn't
set internal clock divider in CLKCR, so it doubles clock
unconditionally when new mode is used.

Some cards can't handle that and as result SPL fails to load u-boot.

223b10ca7a mmc: omap: Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree
