* Allow Raspberry Pi platform and drivers to be configured with upstream DTBs.Ian Lepore2017-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | - Added more compatibility strings to drivers not yet converted - Added new RPI platform code compatibility string to match the ones used upstream - Adapted RPI and RPI2 DTS to match the new platform code compatibility string The goal is to use the upstream DTBs as a replacement for our custom one. This is now possible with these changes. Additionally, as the RPI firmware automatically chooses the right DTB for us, this would allow to have one common armv6 kernel for RPI0 and RPI1 (BCM2835-based), and one common armv7 kernel for RPI2 v1.1 (BCM2836-based), and RPI2 v1.2 / RPI3 (BCM2837-based).

* Increase EFI boot file size frok 128k to 384kAllan Jude2017-09-1311-116/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | generate_fat.sh does the following: - create an 800kb zero-filled file - create an md device backed by this file - format the device fat12 - mount the filesystem - create the EFI ESP directory structure - create the EFI boot file (BOOTx64 for amd64, BOOTaa64 for aarch64, etc) - Adds a marker to the beginning of the file, and pad it to 384kb - 384kb was chosen as it is less than half of 800kb, thus allowing users to keep a backup of their older boot file in the small partition - Unmount the filesystem - Scan the image and find the offset where the marker was inserted - The process requires root, to make image generation easier, images for each architecture are pregenerated, compressed with xz, and checked into svn. The Makefile that generates boot1.efifat does the following: - Ensure the compiled boot1.efi file is no larger than the generated image - Decompress the template created by generate-fat.sh - dd the contents of boot1.efi into boot1.efifat starting at the offset where the marker is found. This allows any file less than the maximum size to be written into the fat filesystem without having to mount it, so no root privileges are required. Later work by imp and myself makes bsdinstall create a 200mb fat16 instead of using this process, but it is retained to make image generation easier.

| | | | | | | | | | | | | | | | | | | | | | | | | In advance of other changes to the fat template generation process, have generate-fat.sh create all template files at the same time so that they cannot get out of sync. Also correct a longstanding but where BOOT1_OFFSET was overwritten on each invocation. A previous version of this patch stored a per-arch offset (e.g. BOOT1_arm64_OFFSET) but that was deemed unnecessary. Instead just hardcode the known offset that applies to all archs (0x2d) and fail if the offset happens to be different. Ongiong work (using newfs_msdos in bsdinstall and adding msdosfs support to makefs) will eventually allow us to do away with this fat template hack altogether, but in the near term we have a few improvements that will build on this.

* Fix loader bug causing too many pages allocation when bootloader is U-BootMarcin Wojtas2017-09-051-0/+7
| | | | | | | | | | | | | | | | | | | | | FreeBSD loader expects to have mmsz variable set by bootloader. U-Boot behaviour is that if buffer size is not big enough to keep whole memory map, assign the smallest correct buffer size to sz and return error. In other words U-Boot assumes that nobody will need mmsz value when buffer is not filled with memory map, which is not true, so calculated pages value was too big to allocate. Solution: Simply assign default value to mmsz.

* Save where we're booted fromWarner Losh2017-08-312-1/+34
| | | | | | | | | | | | | | | | Record the file path for boot1.efi as the UEFI environemnt variable FreeBSDBootVarGUID:Boot1Path. Record the device this came from as FreeBSDBootVarGUID:Boot1Dev. While later stages of the boot may be able to guess these values by retrieving UEFIGlobal:BootCurrent and groveling through the correct UEFIGlobal:BootXXXX, this provides certanty in the face of behavior from any part of the boot loader chain that might "guess" what to do next.

* Exit rather than panic for most errors.Warner Losh2017-08-311-24/+26
| | | | | | | | | | | | | | | | In the FreeBSD UEFI boot protocol, boot1.efi exits back to UEFI if it can't boot the image for most reasons (so that further items in the EFI boot manger list can be tried). Rename panic to efi_panic, make it static and give it an extra status argument. Exit back to UEFI with that status argument so the next loader can be tried.

* Use efi_devpath_str for debug path info.Warner Losh2017-08-264-184/+29
| | | | | | | | | | | | | | | | | | | | | | | Kill our own hand-rolled (and somewhat flawed) devpath_str in favor of the recently added efi_devpath_str in libefi. This gives us much better names at the expense of not being able to debug on EFI 1.2 machines (since the UEFI protocol efi_devpath_str depends on was added in UEFI 2.0). However, this isn't the first thing that requires newer than EFI 1.2, so it's quite possible that this doesn't change the universe of machines we can EFI boot from. This will now give us the full UEFI path, even for devices we don't yet know about. More importantly, it gives us the full HD(...) part of the path, which is sufficient by itself to locate disks that follow the rules (dd one disk (but not partition) to another still needs the rest of the path to disambiguate, but that isn't following the rules that require every GPT table to have globally unique GUIDs for every partion).
