- this patches u-boot default addresses with the same values used in the boot-genio bootscript
- this enables booting extlinux with large kernels and initrd (eg: `EXT=u-boot-menu`)
- backport fixes from upstream u-boot for
- BTRFS (plus enable BTRFS and BZIP2 support for radxa-nio-12l)
- tested with `CARD_DEVICE=/dev/mmcblk1 ROOTFS_TYPE=btrfs BTRFS_COMPRESSION=zstd` (no UFS!)
- also with `EXT=ufs CARD_DEVICE=/dev/sdc ROOTFS_TYPE=btrfs BTRFS_COMPRESSION=zstd` (UFS!)
- 4k block size UFS for UMS: fixes block size issue (USB issues unhandled)
- Enable "bind" command for the Mediatek-standard USB Gadget Ethernet
- this way, one doesn't need to cripple UFS to be able to boot from SD
- USB didn't get the same treatment as it's slow and **not working**...
- ...and beyond me to fix; both OTG and Host mode are funky in u-boot...
- ...but seem to work fine in kernel
- IMPORTANT: keep in mind: "SDcard is NOT UFS (4k block)" and don't fall for traps!
- Network note:
- `setenv ethaddr xx:xx:xx:xx:xx:xx` & `saveenv` & `reset`
- required for network booting; mtk doesn't use random/cpu# MAC
- required for stable MAC in kernel (keep IP from changing, etc)
- Use TFA + libdram to obtain and set the actual memory size.
- Overwrite the memory size in the devicetree that is passed to the kernel with the actual size detected.
- All credit to Bartosz Bilas' work for the mt8188/mt8370.
- This doesn't really "use" TF-A/libdram though, those call bl33 with magic arguments which we read here.
- That is implemented by a patch in TF-A for the mt8195 platform.
- With this, bl2 will pass down the DRAM size it gets from libdram
down to bl33 (u-boot proper) via a magic location
- This is a rework of the implementation for another MTK plat (GRINN)
- small hack to get around stupid "From xx" parsing in Armbian patcher
- also: fix attribution in `0023-watchdog-mtk_wdt-Correct-maximum-timeout-from-15-to`
- 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.
- this prepares everything for the more boards in the family
- which will need `dt/` folder to avoid null-patches
- label & make LEDs useful
- alias mmc0/mmc1 so they match u-boot
- expose i2c3 which is exposed in the 40-pin 27:SCL3 28:SDA3 (blue pins)
- shows up at i2c1 to userspace; why would Collabora alias an undescribed bus?
- 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
- For 6.18 + 6.19
- mixtile-blade3: add 4-pin header fan at 40c
- mixtile-blade3: add gpu nodes
- mixtile-blade3: add vcc5v0-host-en "usb" pinctrl
- somehow results in 2 working RTL8169's behind the ASM1182e on pcie2x1l0
- which just means the _schematics lie_
- mixtile-blade3: drop rst pinctrl from pcie2x1l0 and pcie2x1l1
- this is me probably being stupid, but also required for working ASM1182e/RTL8169
- Status of this mainline port:
- Initially started by Joshua Riek (2023?)
- I then added some PCIe3x4 stuff, but never got around to finishing it
- Specifically, the 2 FUSB302's are beyond me for now
- One of them _powers_ the board. To use with mainline, power the board some other way with 12V, otherwise kaboom.
- See sre's talk on this issue; Blade3 should be similar to Rock-5b in this aspect.
- A challenge has been the PCI2x1 lanes to the miniPCIe and ASM1182e switch
- Which by themselves seem to work, but the devices behind them (Switch + RTL8169 NICs) do not get powered
- Until one day I tried to describe a (in theory) USB-related power pin, and suddenly both PCIe NICs started working!
- All that said, the board is really not stable with this; end-users are much better off with vendor kernel for now.
- Any and all help is appreciated. Those boards are nice, they've 2 FUSB302, and fancy PCIe Endpoint mode stuff.
- Schematics we have access to are in https://damwold5pt25n.cloudfront.net/blade3/file/Schematic_Blade_3_v1.1.0.pdf
- Those clearly lie.
* rtw88 mainline driver has good enough support for rtl8723cs
so stop patching the kernel with this ancient driver
* fixes rtl8703b (same chip as 8723cs) bluetooth firmware name file
- The deleted patch is not necessary because rkvdec patch v7 has removed
h264 sps check at start. And future version of chromium can also get rid
of the issue that patch has fixed.
- rpardini: squash with removal of v5
