| | | | | | | | | | | | | | | | | | | Fix powerpc 64 little endian booting by adding some padding. Due to https://gitlab.com/slof/slof/-/blob/master/lib/libelf/elf32.c?ref_type=heads#L114 https://gitlab.com/slof/slof/-/blob/master/lib/libelf/elf32.c?ref_type=heads#L150 using <= instead of <, slof used to loop over the phdrs. It overruns by 1 and so on little endian it swizzles the first 32 bytes of .text. Work around this by adding 32 bytes of padding after the headers. We should fix this in slof, but it's in the just released QEMU 10.2, so we have to pad things here for now. Now powerpc64le + qemu works.

* loader: always install help filesMitchell Horne2023-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Address two issues with current help file logic: The existing condition prevents the common help file from being installed when there are no additional help files defined. This results in no loader.help on EFI platforms, for example. Second, due to the fact that we build and install multiple loader types, each successive install will clobber the previous loader.help. The result is that we could lose type-specific commands, or possibly list them in loaders that do not have such commands. Instead, give each loader type a uniquely named help file. The EFI loader will look for /boot/loader.help.efi, userboot will look for /boot/loader.help.userboot, etc. The interpreter variant has no effect on which help file is loaded. This leaves the old /boot/loader.help unused. Some credit for the final approach goes to Mathieu <sigsys@gmail.com> for their version of the fix in https://reviews.freebsd.org/D22951.

* powerpc64le: stand fixesLeandro Lupori2021-10-208-22/+371
| | | | | | | | | | | | | | | | | | | | | | Fix boot1 and loader on PowerPC64 little-endian (LE). Due to endian issues, boot1 couldn't find the UFS boot partition and loader wasn't able to load the kernel. Most of the issues happened because boot1 and loader were BE binaries trying to access LE UFS partitions and because loader expects the kernel ELF image to use the same endian as itself. To fix these issues, boot1 and loader are now built as LE binaries on PPC64LE. To support this, the functions that call OpenFirmware were enhanced to correctly perform endian conversion on its input and output arguments and to change the CPU into BE mode before making the calls, as OpenFirmware always runs in BE. Besides that, some other small fixes were needed.
