[Buildroot] [PATCH v3 0/2] Generate ADI ADSP boot streams

[Buildroot] [PATCH v3 0/2] Generate ADI ADSP boot streams

[Philip Molloy]

From: Philip Molloy <philip.molloy@analog.com>

adsp-ldr is a command-line tool that generates boot streams for ADI ADSP
processors. It is required to boot U-Boot on ADSP processors. This series is
the first step in adding support for the SC598 EZ-KIT evaluation board, and
eventually other boards.

Successful pipeline for this series:

https://gitlab.com/pamolloy/buildroot/-/pipelines/2027407298

Branch containing this series:

  git clone -b staging/philip/adsp-ldr https://github.com/analogdevicesinc/buildroot.git

The entire series adding support for the SC598 EZ-KIT evaluation board:

  git clone -b staging/philip/support-sc5xx-eval-boards https://github.com/analogdevicesinc/buildroot.git

---
Changes v2 -> v3:
- Consolidate BR2_TARGET_UBOOT_FORMAT_ADSP_LDR conditionals
- Add help for BR2_TARGET_UBOOT_FORMAT_ADSP_LDR
- Update comment in HOST_ADSP_LDR_INSTALL_CMDS

Changes v1 -> v2:
- Bump to adsp-ldr from v1.0.0 to v1.0.1
    - Replace autotools with meson
    - The version is generated using git describe and added to a custom source
      archive using meson dist. Since Github doesn't support modifying source
      archives use the custom archive added to the Github release
    - Remove GPL source code and add dependency on libusb
    - Remove _SUBDIR
- Squash PATCH 4/4 modifying DEVELOPERS
- Move Config.in to Config.in.host
- Add host-adsp-ldr as a dependency to U-Boot when
  BR2_TARGET_UBOOT_FORMAT_ADSP_LDR is enabled
- Add comment explaining $(TARGET_CROSS)ldr installation

This license file hash was incorrect, so I fixed it up, and finally
applied your patch!

Sorry for the long delay.
