[PATCH v2 0/3] stm32mp1: board: add support of CONFIG_ENV_IS_IN_MMC

[Patrick Delaunay]

Hi,

Rebased serie [1] with minor modification for avenger96 board
(as SD card is no more used for environment, replaced by SPI-NOR)

This serie depends on ENV patches [2] (RESEND of [3])

[1] http://patchwork.ozlabs.org/project/uboot/list/?series=165333
[2] http://patchwork.ozlabs.org/project/uboot/list/?series=183363
[3] http://patchwork.ozlabs.org/project/uboot/list/?series=165325

Patrick

Changes in v2:
- remove impact on avenger96 board as ENV is saved in NOR for DHCOR SOM
  (CONFIG_ENV_IS_IN_SPI_FLASH in stm32mp15_dhcor_basic_defconfig)

[PATCH v2 1/3] stm32mp1: board: add support of CONFIG_ENV_IS_IN_MMC

[Patrick Delaunay]

Add support of CONFIG_ENV_IS_IN_MMC in env_get_location, used for
all mmc device (SD card and eMMC).
The 2 configs CONFIG_ENV_IS_IN_MMC and CONFIG_ENV_IS_IN_EXT4 are
incompatible.

Add the weak function mmc_get_env_dev to select the mmc boot instance.

[PATCH v2 2/3] stm32mp1: use a specific SD/eMMC partition for U-Boot enviromnent

[Patrick Delaunay]

Save the environment at the end of the U-Boot partition, the GPT
partition named "ssbl" in SD card or eMMC and avoid requirements
on the "bootfs" file system generated via specific raw tools
(like wic and genimage).

With the previous configuration of the U-Boot environment saved in ext4
file, U-Boot need to create/modify the file uenv.txt in the ext4 file
system; so this EXT4 file system need to be generated without some
functionality, like metadata_csum and dir_index, because they are not
supported by U-Boot.
