The cgroup_enable parameter is a Raspberry Pi kernel specific kernel
parameter. Upstream based kernel do not have the parameter, and hence
do not do anything.
This gets rid of the following message during boot:
Unknown kernel command line parameters "cgroup_enable=memory", will be passed to user space.
* Linux: Update kernel 5.15.25
Use highest available kernel version in Buildroot 2021.08 (5.13)
* Update Hardkernel patches to Linux 5.15
* Update generic-x86-64/ova kernel config/patches for 5.15
* Drop Intel e1000e Sourceforge driver
The driver has been discontinued sometime last year. The main reason the
out-of-tree kernel has been enabled was for support for the i219-V
network chips which meanwhile are supported in mainline.
To make HDMI CEC work, we have to compile MESON_DRM as a module
(see #1717). However, this essentially reverts #1347, which fixed the
reboot problem by compiling the driver into the kernel.
Hence we need to reintroduce the earlier fix from #1345, which reverts
the offending commit causing the reboot problem.
* Remove duplicate config.txt copy statement
* Use static cmdline.txt file
Instead of dynamically creating cmdline.txt use a static version of it.
This aligns with other boot loader/firmware configuration files and makes
it easier to customize the file per board.
The bump to U-Boot 2021.10-rc5 also makes quite some patches obsolete
since they are already part of U-Boot.
This also removes a patch which disables framebuffer support on
Raspberry Pi: Framebuffer support seems to work fine in todays
U-Boot/Linux combination. It can help debug boot problems on Raspberry
Pi devices. Without the patch framebuffer support will be enabled by
default.
* Linux: Update kernel 5.10.61 for ODROID-N2 (#1512)
Update the kernel to 5.10.61 for ODROID-N2 and fix the update script
to update kernel for ODROID-N2 next time too.
* Move ODROID kernel patches to non-kernel version specific directory
Don't fail adding reserved memory when a memory region already has been
reserved (e.g. via memreserve). This avoids conflicting no-map setting
and makes sure memory is properly reserved.
The CRDA (Central Regulatory Domain Agent) utility has been used as a
user space helper to load regulatory information for WiFi drivers.
However, since Linux 4.15 the kernel can load the regulatory information
directly from a signed firmware file "regulatory.db".
The regulatory.db file is provided by the WIRELESS_REGDB package, which
has been already installed since its a dependency of CRDA.
Drop CRDA and select WIRELESS_REGDB package explicitly to make sure the
regulatory.db file is present.
* Add squashfs with LZ4 and LZO compression to Barebox
* Add squashfs with LZO compression to U-Boot
* Use squashfs for Linux kernel partition
Generate a squashfs image with LZO compression for the Linux kernel
partition. Adjust the boot scripts to be file system independent commands
to boot from squashfs.
The patches for ODROID-C2/C4 don't apply to Linux 5.12 used in
ODROID-N2. Move ODROID-C2/C4 patches to kernel version specific
directory so they don't get applied for ODROID-N2.
Use the latest Linux stable release 5.12 for ODROID-N2. This allows to
test if we see the random kernel crashes observed with 5.10 in latest
stable 5.12 as well.
It seems that the TPU (thermal monitoring) sometimes reports
unreasonable high temperatures, leading the kernel to trigger a thermal
shutdown. Add a patch which filters out such spurious temperature
readings.
Since the move to 5.10 multiple users experience stability issues
leading to random crashes. All reboots follow a SError Interrupt:
[48112.247242] SError Interrupt on CPU5, code 0xbf000000 -- SError
...
Revert back to Linux 5.9.16 for now.
It seems that the crash of the Meson DRM driver on shutdown can also be
fixed by compiling it in. The driver is also built-in in LibreELEC,
hence this is better tested by the upstream community.
Note the underlying issue seems to be a disabled clock: Since the
introduction of meson_drv_shutdown some registers are touched at a very
late stage. Those clock get disabled in meson_ee_pwrc_shutdown. It seems
that when the driver is built-in, meson_drv_shutdown gets called before
meson_ee_pwrc_shutdown and hence sidesteps the problem.
Note: This increases the kernel by a bit since DRM needs to be built-in
as well. Configure some less common used file systems as modules
(ext3/NFS).
In Linux 5.10.24 a regression has been introduced which broke reboot on
ODROID-N2(+). Interestingly the patch should improve reboot stability
for VIM3, which uses the same SoC. However, it seems that in the
ODROID-N2 case, this causes more problems then it fixes. Revert the
offending patch.
* Re-add patches missed with U-Boot 2021.04-rc4 upgrade
Also add patches for Raspberry Pi again.
* Regenerate patches for U-Boot 2021.04
* Update to U-Boot 2021.04
Bump to the latest U-Boot release 2021.04-rc4. This alows to drop quite
some patches which have been sent to the mailing list or picked from the
mailing list and have been merged upstream now.
* Add Ralink rt27xx/rt28xx/rt30xx firmware (#1242)
Add Ralink firmware for devices which have the driver enabled. The
firmware's are rather small at 20KiB in total.
* Remove Ralink and other WiFi drivers from Tinker Board
The board has on-board WiFi, no need for Ralink drivers to be enabled.
* Add Ralink WiFi drivers and firmware to ODROID boards
* Drop ODROID specific kernel update script
With the jump to Linux 5.10 LTS we can use the same upstream kernel for
Hardkernel ODROID boards as well. Extend the update-kernel-upstream.sh
to support the ODROID boards.
* Linux: Update kernel 5.10.13
* Add Realtek RTL8812AU out-of-tree driver
This adds support for Realtek RTL8812AU devices such as the Hardkernel
WiFi Module 5A (with the RTL8811AU chipset, supported by this driver as
well). This patch uses Realtek driver 5.9.3.2 which has been made to
compile up to Linux 5.10.
Note: This driver does not seem to support 5GHz networks! But it seems
the only driver which supports the RTL8811AU chipset and also works with
recent mainline drivers...
* Enable RTL8812AU driver for Hardkernel modules
The WiFi Module 5A comes with a RTL8811AU chipset. Enable the driver for
all Hardkernel modules.
* Revert "Fix boot from 128GB Micron eMMC on ODROID-N2(+) (#1064)"
This reverts commit 162084082e.
This patches seem to cause issue on a ODROID-N2 with 32GB eMMC.
* Cap eMMC frequency to 24MHz in U-Boot for ODROID-N2(+)
Also remove the ODROID-C4 specific patch.
Fix ethernet PHY reset timing to make sure the link comes up when
reconfiguring the link.
Also drop 0006-clk-meson-g12a-mark-fclk_div2-as-critical.patch which has
been applied in v5.9.2 stable release.
The version banner was showing "Amlogic Meson G12A (Unknown) Revision
28:0 (0:0)" in all cases instead of the correct SoC name and revision.
Make sure the SoC revision is properly read also for the banner.
The change "Avoid trying to boot non-existing kernel image in failover
case" introduced a broken boot script on Raspberry Pi (when booting from
partition B) and ODROID-XU4.
* Avoid trying to boot non-existing kernel image in fail-over case
The A/B update system automatically switches to the other boot slot when
booting fails. However, in a fresh installation, only boot slot A
exists. If booting fails three times (e.g. if somebody plugs out power
before the slot can be marked as good), then the system switches to boot
slot B which does not contain a kernel image yet. Avoid trying to boot
the non-existing kernel image.
With this change, if slot B is empty U-Boot will restore both slots to 3
attempts and retry booting from slot A on next reboot:
```
Trying to boot slot B, 2 attempts remaining. Loading kernel ...
** Unrecognized filesystem type **
No valid slot found, resetting tries to 3
storing env...
```

* Fix N2+ boot by disabling USB enumeration
On some devices USB enumeration in U-Boot seems to freeze:
starting USB...
Bus usb@ff500000: Register 3000140 NbrPorts 3
Starting the controller
USB XHCI 1.10
scanning bus usb@ff500000 for devices... <freeze>
We don't use USB currenty in the U-Boot script, disable it for now.
* Disable USB enumeration on all ODROID devices
