0a6f0297c6 ARM: mvebu: x530: clearfog: Add ODT configuration
Commit 369e532691 ("ddr: marvell: a38x: allow board specific ODT
configuration") added the odt_config member to struct
mv_ddr_topology_map ahead of the clk_enable and ck_delay members. This
means that any boards that configured either of clk_enable or ck_delay
needed to have their board topology updated. This affects the x530 and
clearfog boards. Other A38x boards don't touch any of the trailing
members of mv_ddr_topology_map so don't need updating.

2226ca1734 arm: mvebu: Load U-Boot proper binary in SPL code based on kwbimage header
Now that proper load and execution addresses are set in v1 kwbimage we
can use it for loading and booting U-Boot proper.

Use the new spl_parse_board_header() function to implement parsing the
kwbimage v1 header. Use information from this header to locate offset and
size of the U-Boot proper binary, instead of using the legacy U-Boot
header which is prepended to the U-Boot proper binary stored at fixed
offset. This has the advantage that we do not need to relay on legacy
U-Boot header anymore and therefore U-Boot proper binary can be stored at
any offset, as is the case when loading & booting U-Boot proper by
BootROM. The CONFIG_SYS_U_BOOT_OFFS option is therefore not used by SPL
code anymore.

Also allow to compile U-Boot SPL without CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_MMC_SUPPORT or CONFIG_SPL_SATA_SUPPORT set. In this case
BootROM is used for loading and executing U-Boot proper. This reduces the
size of U-Boot's SPL image. By default these config options are enabled
and so BootROM loading is not used. In some cases BootROM reads from SPI
NOR at lower speed than U-Boot SPL. So people can decide whether they
want to have smaller SPL binary at the cost of slower boot.

Therefore dependency on CONFIG_SPL_DM_SPI, CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_SPI_LOAD, CONFIG_SPL_SPI_SUPPORT, CONFIG_SPL_DM_GPIO,
CONFIG_SPL_DM_MMC, CONFIG_SPL_GPIO_SUPPORT, CONFIG_SPL_LIBDISK_SUPPORT,
CONFIG_SPL_MMC_SUPPORT, CONFIG_SPL_SATA_SUPPORT and
CONFIG_SPL_LIBDISK_SUPPORT is changed from strict to related "imply"
(which can be selectivelly turned off and causes booting via BootROM).

Options CONFIG_SYS_SPI_U_BOOT_OFFS,
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR and
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET have to to be set to
zero as they define the location where kwbimage header starts. It is the
location where BootROM expects start of the kwbimage from which it reads,
parses and executes SPL part. The same applies to option
CONFIG_SPL_SATA_RAW_U_BOOT_SECTOR, which has to be set to one.

Update all config files to set correct values of these options and set
CONFIG_SYS_U_BOOT_OFFS to the correct value - the offset where U-Boot
proper starts.

a4c577f981 mmc: mmc_get_op_cond: Allow quiet detection of eMMC
Add a new 'quiet' argument to mmc_get_op_cond() function which avoids
printing error message when SD/eMMC card is not detected.

Espressobin and mx6cuboxi boards use this function for detecting presence
of eMMC and therefore it is expected and normal that eMMC does not have to
be connected. So error message "Card did not respond to voltage select!"
should be skipped in this case as it is not an error.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

6c3fbf3e45 mx6cuboxi: customize board_boot_order to access eMMC
In SPL legacy code only one MMC device is created, based on BOOT_CFG
register, which can be either SD or eMMC. In this context
board_boot_order return always MMC1 when configure to boot from
SD/eMMC. After switching to DM both SD and eMMC devices are created
based on the information available on DT, but as board_boot_order
only returns MMC1 is not possible to boot from eMMC.

This patch customizes board_boot_order taking into account BOOT_CFG
register to point to correct MMC1 / MMC2 device. Additionally, handle
IO mux for the desired boot device.

We should not use typedefs in U-Boot. They cannot be used as forward

Drop the typedef and rename the struct to remove the _s suffix which is

c3dc39a2f8 arm: Don't include common.h in header files
It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.

Update some header files in arch/arm to drop this.

eb9124f574 mx6cuboxi: enable OF_CONTROL with DM_MMC and DM_USB
Make first step in DT/DM migration. Enable OF_CONTROL only for the main
U-Boot image for now.

Remove mmc_init_main() because board_mmc_init() is not called when
DM_MMC is enabled.

DM_MMC requires DM_GPIO for card-detect to work. That in turn makes gpio
request mandatory. Add code to request/free gpios in platform code.

MMC devices are now numbered according to DT. The SD card is 1, and eMMC
is 2. Account for that in board_mmc_get_env_dev(), BOOT_TARGET_DEVICES,
and has_emmc().

DM_MMC requires BLK. However, the (BLK && !DM_USB) combination disables
USB_STORAGE. Enable DM_USB to preserve USB functionality. Add also
DM_REGULATORS for the USB power controller. This allows us to drop
board_ehci_hcd_init() and setup_usb().

Runtime selection of DT is necessary because of the i.MX6QD vs i.MX6SDL
incompatibility. DT selection does not rely on GPIOs, since DM_GPIO
depends on DT. Instead, we take one "fully featured" DT of each variant.
That should be enough to boot from both SD card and eMMC.

Since we don't select the exact DT, override the generic
show_board_info() that shows the selected DT 'model' field.

ebb1a59325 ARM: mvebu: a38x: sync ddr training code with mv_ddr-armada-18.09.02
This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").

The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:

  ddr3: add missing txsdll parameter
  ddr3: fix tfaw timimg parameter
  ddr3: fix trrd timimg parameter
  merge ddr3 topology header file with mv_ddr_topology one
  mv_ddr: a38x: fix zero memory size scrubbing issue

The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef

    find drivers/ddr/marvell/a38x/ -name '*.[ch]' | \
        xargs unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 \

19ed6063a5 mx6cuboxi: Use mmc_get_op_cond() to check for an eMMC
Previously we had just made broad assumptions with which of our
boards had an eMMC or not even though this is a manufacturing time
assembly option.  This takes the guessing away and actually checks for
the existence of an eMMC and sets up the has_emmc environment variable.

51f957adf7 mx6cuboxi: fix 4GB ddr memory detection
The soms with 4GB ddr have a rowaddr of 16 not 15, this allows
the detection mechanism to properly identify them as 4GB.
However these soms can be populated with whatever amount of
memory the customer requests therefor we need a ram stride test.
We can not use the get_ram_size() function because not all 4GB's
of DDR is addressable on a 32-bit architecture.  Therefore instead
we use a memory stride of 128MB's and look for the address that
the memory wraps.  This function is used for all som types to
catch most memory configurations.

This is a revised version of Rabeeh Khoury's original code.

73708200f0 mx6cuboxi: consolidate board detection and add som revision checking
In order to properly detect the board the checks need to be done
in a specific order.  Move these tests back into a single enum
function that will always return the proper the board it is checking.

This also adds the best test we have for detecting the rev 1.5 som,
and it simplifies the device-tree filename building.
