To make panel driver upstreamable to mainline linux, we need to use
proper panel selection in secondary bootloader (still TODO), and
therefore lk2nd will be strictly required to boot mainline port.
Switch flashing method to fastboot, enable sparse rootfs generation,
and depend on lk2nd package.
Depends on: postmarketOS/pmbootstrap!2174, to provide full
integration of lk2nd in pmbootstrap.
So, full flashing procedure for samsung-klte will look like:
$ pmbootstrap init
$ pmbootstrap install
$ pmbootstrap flasher --method=heimdall-bootimg flash_lk2nd
$ pmbootstrap flasher flash_kernel --no-install
$ pmbootstrap flasher flash_rootfs
$ fastboot reboot
This is needed with the 5.11 kernel. Also adjust the vram & cma sizes
for all msm8974 devices.
The CMA size is 256MB as set in the kernel config.
VRAM is default 16MB although it is set to 192MB with a kernel patch;
but set it manually for all devices to make it possible to remove this
patch in the future - until we have IOMMU working.
* make modules_initfs same as lg-hammerhead
(fixes postmarketOS splash logos at boot)
* split out downstream-firmware and mainline-firmware
* add firmware-adreno to firmware-mainline subpkg
* prepare deviceinfo file to mainline kernel
Prepare for better device categorization by moving everything to testing
subdir first.
[skip-ci]: chicken-egg problem: passing pmaports CI depends on pmbootstrap MR
depends on this MR
