This switches the ROCK64 over to the open-source RAM init as it now
works flawlessly. It also removes the HDCP flag from the ATF for the
RK3328 as it cannot use it, it is only used in the RK3399. This makes
the ROCK64 u-boot now fully open.
There is also an issue with the ROCK64 v2 revision where the DRAM
routing is marginal, making some of them unstable. So also package a
variant which uses a lower-speed DDR3 timing configuration which is
stable on these boards.
When we're building a ubootTools, we want to produce a set of tools that runs
on the host, so we want their dependencies to be built for hostPlatform.
When we're building an uboot, the tools will run on the builder as part
of the build, so we want their dependencies to be built for buildPlatform.
`efivar.py` enable a user to manipulate the EFI variable store on disk
that U-Boot uses.
This is useful to prepare a SecureBoot set of variables that can be seeded
inside of U-Boot directly if you do not have a proper OP-TEE on your platform.
Sometimes, U-Boot has interesting Python scripts in tools/, the issue is
that they rely on implicit dependencies described by their code itself.
For this, we offer an attribute set-style option to install Python scripts
with specific dependencies.
For example, you could do `pythonScriptsToInstall."tools/efivar.py" = python3.withPackages (ps: [ ps.pyopenssl ]);`
which will be added in a next PR.
As far as I can tell, there are no makefile targets to install these, or
anything like that, so we have to do it by hand.
This adds man pages for dumpimage, kwboot, mkeficapsule, and mkimage.
There are no man pages in other sections than 1.
This reverts commit 8b3a31f923.
commit 8c80bd08b7
("build-support/cc-wrapper: pass in non-existent --sysroot= to untangle
from libc") was reverted. We can drop the workaround.
`ubootTools` build broke after https://github.com/NixOS/nixpkgs/pull/210004
where we started dropping default libc include path and switched to
`-idirafter` way of specifying libc headers.
Unfortunately the way it's implemented it injects -idirafter after
user's flags, not before. That allows users to inject their paths before
libc include paths, not after (as it would notmally happen).
The change works it around for u-boot by pulling -idirafter libc flags
before user's flags.
Add a new U-boot flavor for LibreComputer's AML-S905X-CC (Le Potato).
Board's SoC is based on Trusted Firmware-A architecture and needs extra
closed-source early bootloaders to be combined with U-boot in order to
boot properly, similar to Odroid-C2 board.
Proprietary blobs and related tooling are fetched from
github.com/LibreELEC/amlogic-boot-fip and used in postBuild along with
build output.
