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.
