2023-01-18gnu: Add u-boot-ts7970-q-2g-1000mhz-c-bootloader....* gnu/bootloader/u-boot.scm (u-boot-ts7970-q-2g-1000mhz-c-bootloader): New variable. Maxim Cournoyer
2022-12-28gnu: u-boot-am335x-boneblack: Revert to old name....This reverts to the name this package had previous to commit c2c1dfdf5760873f1db86d14873f725a105f7feb ("gnu: bootloader: Add U-Boot packages for Raspberry Pi models."), which caused the package name to be derived from the board name. * gnu/packages/bootloaders.scm (u-boot-am335x-evm-boneblack): Remove the NAME-SUFFIX keyword argument. Specify the full name via the name field. * gnu/bootloader/u-boot.scm (u-boot-beaglebone-black-bootloader): Adjust to the renamed package. Reported-by: Vagrant Cascadian <vagrant@debian.org> Maxim Cournoyer
2022-12-20gnu: u-boot-am335x-evm-boneblack: Fix variable name....* gnu/packages/bootloaders.scm (u-boot-am335x-boneblack): Rename to... (u-boot-am335x-evm-boneblack), to match the package name. * gnu/bootloader/u-boot.scm (u-boot-beaglebone-black-bootloader): Adjust accordingly. Maxim Cournoyer
2022-12-07bootloaders: grub: Fix comment....* gnu/bootloader/grub.scm (make-grub-configuration): Refer to the correct argument in comment. Maxim Cournoyer
2022-12-01gnu: bootloader: Rework chaining, add grub-efi-netboot-removable-bootloader....This rework allows to use an (efi-bootloader-chain) like this, which is able to boot over network or local storage, depending on whether the bootloader target has support for symbolic links: (operating-system (bootloader (bootloader-configuration (bootloader (efi-bootloader-chain grub-efi-netboot-removable-bootloader #:packages (list my-firmware-package my-u-boot-package) #:files (list (plain-file "config.txt" "kernel=u-boot.bin")) #:hooks my-special-bootloader-profile-manipulator)) (targets '("/booti/efi")) …)) …) * doc/guix.texi (Bootloader Configuration): Describe the new ‘grub-efi-netboot-removable-bootloader’. Mention the file names used and that the UEFI Boot Manager is not modified. Advise to disable write-access over TFTP. * gnu/bootloader.scm (efi-bootloader-profile): Allow a list of packages and collect everything directly in the profile, avoiding a separate collection directory. Renamed the profile from "bootloader-profile" to "efi-bootloader-profile". [bootloader-collection]: Rename to... [efi-bootloader-profile-hook]: ... this and remove unused modules. Do not create the now extraneous collection directory. (efi-bootloader-chain): Add PACKAGES and DISK-IMAGE-INSTALLER arguments. Remove handling of the collection directory, now only calling the given installer procedure. * gnu/bootloader/grub.scm (make-grub-efi-netboot-installer): New helper. (make-grub-configuration): New helper based on (grub-configuration-file). Add a GRUB argument, fix indentation, remove previous code retrieving GRUB from CONFIG. (grub-configuration-file): Make use of make-grub-configuration. (grub-efi-configuration-file): New procedure. (grub-cfg): New variable to replace "/boot/grub/grub.cfg". (install-grub-efi-netboot): Remove, splitting logic to... (make-grub-efi-netboot-installer): ... this new helper procedure, as well as to make-grub-efi-netboot, added below. (grub-bootloader): Adjust to use the GRUB-CFG. (grub-efi-bootloader): Likewise. Removed inheritance and declare all fields explicitly. (make-grub-efi-netboot-bootloader): New procedure. (grub-efi-netboot-bootloader): Use it. (grub-efi-netboot-removable-bootloader): New variable. * gnu/packages/bootloaders.scm (make-grub-efi-netboot): New procedure.
