- move patches into version folder (`atf-rockchip` -> `atf-rockchip/v2.13`)
- also prepares patches for v2.14 since I had them anyway
- keeps using v2.13 for now, someone can test v2.14 later and bump; I've no rk3399
- new patches:
- add `-no-pie` to rk3399's m0 build LDFLAGS (since upstream doesn't honor M0_LDFLAGS)
- bump PMSURAM_RSIZE from 8k to 16k to avoid overflows - confirmed working by Amazingfate
- build tested OK on jammy/bookworm/trixie/noble/resolute
- resolute's gcc 15 and it still builds
- desktop images have half the world in their initrd (plymouth?)
- `bdinfo` shows reserved regions, which are hit depending on the size of initrd
- when reserved region is hit, u-boot says `** Reading file would overwrite reserved memory **`
- done by AI after looking at `bdinfo` reserved regions
- hard lesson: all `0x` hex have to be double quoted, otherwise `Wrong image format for "source" command`
- add note about Meco having conjured up `load_addr` (it's `loadaddr`); doesn't hurt
- while at it, remove copypasta/duplicate bootlogo/consoleargs stanza
- u-boot stores env in UFS LUN 1
- use a 2mb offset (different from vendor/Collabora's) to avoid any env conflict
- point fw_printenv/setenv at it at the correct offset and size
- set SRC_CMDLINE, used in extlinux/EXT=u-boot-menu scenarios
- note about d4/d8/d16 irrelevance now as we have RAM autodetection
- note about where the blobs (libdram/libbase/lk.bin) live in GH: https://github.com/armbian/mtkbin
- genio: implemented complete bootloader build according to Collabora's scripts
- main difference from other similar stack is that TF-A builds final FIP, not u-boot
- thus I first disable ATF build initially, then build it in hook
- alternatively: we could build our own FIP, but that would diverge too much
- declare functions inside hook so hashing does all the versioning automatically
- write_uboot_platform() is a no-op; don't write bootloader to image
- ensure bootloader _builds_ across bookworm/trixie/jammy/noble/resolute
- keep in mind original code is for bookworm (tested to build and work on trixie)
- need to juggle the `-Wl,` prefix on LDFLAGS
- this is not mainline ATF and it does "stupid with flags"
- genio: u-boot: always clean optee & first atf build before building
- so one can switch build host with `DOCKER_ARMBIAN_BASE_IMAGE` (UFS...)
- genio: u-boot: using `armbian/mtkbin` repo
- outputs fip.img & lk.bin directly to output(/images)
- disk images do _not_ contain any bootloader
- Switched to the binman-atf-mainline scenario with the same rkbin DDR blob
rk3399_ddr_933MHz_v1.25.bin (TPL blob, as in the old working loader). DRAM init is correct, full
4 GB visible, Linux boots.
- U-Boot and DTS updated to v2026.01-rc5. Added MDIO/PHY node and phy-handle in rk3399-kobol-
helios64.dts, fixing “mdio node is missing”. Disabled i2s2 in the U-Boot DT to avoid rockchip-
i2s ... Could not register PCM.
- boot_targets in U-Boot config shortened (mmc1, scsi0, usb0, pxe, dhcp) to avoid env_buf ... too
small; however, the last built binary still shows the warning (needs rebuild with the shortened
list or enlarging the buffer).
- Boot flow: bootstd scans SD (mmc0) and eMMC (mmc1); SD boot works even without mmc0 in
boot_targets.
- Other changes: defconfig has CONFIG_ROCKCHIP_EXTERNAL_TPL=y to use the external DDR blob.
Boots.
- while it is nice having them, and also a good test of being able to
build the headers "board-side", enabling it by default should be a
global change, and not specific to genio
- fix bootorder (SD -> NVMe -> eMMC); USB disabled as nonworking with mainline still
- use the DT from rockchip64-6.18 so a single source for both u-boot and kernel
- note: the first (and only) RTL8169 used by u-boot is the port closest to board edge
* DFI driver fix to let DDR3 rk322x handle DMC driver
* edge kernel: removal for Gigabit Ethernet DMA
workaround for rk3288
* reinstate CONFIG_DEBUG_FS=y with both current/edge kernels
