Opensbi is now based on 1.1, U-Boot on 2022.07-rc3 and Linux on 5.19-rc1.
We don't yet support 5.19 kernel headers, so use 5.17 instead.
The incompatibility between opensbi and u-boot is now fixed, so drop
0001-arch-riscv-dts-sun20i-d1.dtsi-adjust-plic-compatible.patch.
The updated device tree in the kernel tree no longer specifies a memory
node (and the board exists in 512M/1G/2G variants, so instead use the
(otherwise identical) device tree provided by u-boot, where the memory
node is fixed up based on the detected memory size.
On riscv, the linux kernel unconditionally wants to build its bundled
dtc, so it needs flex and bison, even if it is not going to build any
DTB. We can get flex and bison either via the system ones, or we get
them as they are in LINUX_KCONFIG_DEPENDENCIES. However, relying on this
is a bit fragile, so we keep asking the kernel to build a DTB, so that
we do ensure that our host-{flex,bison} are built and in the dependency
chain of the kernel (for PPD).

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
