[PATCH u-boot-mvebu v2 00/18] Turris Omnia - New board revision support

["Marek Behún" <kabel@kernel.org>]

Hi Stefan,

this is v2 of series adding support for new board revision of Turris
Omnia.

See v1 at
  https://patchwork.ozlabs.org/project/uboot/cover/20240304152148.3847-1-kabel@kernel.org/

Changes since v1:
- MCU firmware features can be 32-bit wide, updated the code to support
  reading 32 bits of features (both in board driver and in gpio driver)
- gpio driver now moved to misc, since it handles more functionality
  (rng, sysreset)
- mvebu system-controller driver expanded to also support UCLASS_SYSRESET,
  configurable by config option
- LTO enabled by default for Turris Omnia, otherwise it won't fit into
  the space reserved for U-Boot with these changes
- enabled the poweroff command (via sysreset) in defconfig (new MCU
  firmware can power off the board voltage regulators)
- enabled the rng command in defconfig

Marek Behún (18):
  arm: mvebu: turris_omnia: Enable LTO by default on Turris Omnia
  arm: mvebu: turris_omnia: Add header containing MCU command interface
    and use it

  arm: mvebu: system-controller: Select mvebu-reset if DM_RESET &&
    PCI_MVEBU
  arm: mvebu: system-controller: Add support for SYSRESET
  gpio: turris_omnia_mcu: Use byteorder conversion functions
