c733fe91e4 arm: mvebu: clearfog: Detect MMC vs SDHC and fixup fdt
[upstream of vendor commit 19a96f7c40a8fc1d0a6546ac2418d966e5840a99]

The Clearfog devices have only one SDHC device. This is either eMMC if
it is populated on the SOM or SDHC if not. The Linux device tree assumes
the SDHC case. Detect if the device is an eMMC and fixup the device-tree
so it will be detected by Linux.

847fca6d47 imx: Use SATA instead of CMD_SATA
This causes a build failure on mx6cuboxi with split config, since CMD_SATA

The condition is wrong anyway, so change it to use SATA instead.

SoM revision 1.9 has replaced the ar8035 phy address 0 with an adin1300
at address 1. Because early SoMs had a hardware flaw, the ar8035 can
also appear at address 4 - making it a total of 3 phy nodes in the DTB.

the phy node that is detected at runtime.

Commit 369e532691 ("ddr: marvell: a38x: allow board specific ODT

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.

Espressobin and mx6cuboxi boards use this function for detecting presence

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.

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.
