- update the 5.4 kernel baseline from 5.4.284 to 5.4.302
- rebase the affected generic patches, including the MikroTik build bits and codel backport, to the 5.4.302 source context
- rebase the affected MediaTek TRNG and PWM patches to the new source context
- adjust 993-usb-serial-option-add-u9300.patch so the LONGSUNG U9300 modem patch still applies after the qmi_wwan changes
The driver for MediaTek gen3 PCIe hosts de-asserts all reset
signals at the same time using a single register write operation.
Delay the de-assertion of the #PERST signal by 100ms as some PCIe
devices fail to come up otherwise.

Gain SSH access:
1. Login into web interface, and download the configuration.
2. Download the configration utilities:
https://firmware.download.immortalwrt.eu.org/cnsztl/mediatek/filogic/openwrt-mediatek-mt7981-nokia-ea0326gmp-config-utils.tar.gz
These binaries are extraced from the factory firmware, which are
dynamically linked with aarch64 musl 1.1.24. To use them, you
must run them under the same runtime environment, otherwise the
binaries will not work!
3. Upload the configuration and utilities to a suitable environment.
4. Uncompress the utilities, move them to '/bin' and give them executable permisison:
tar -zxf openwrt-mediatek-mt7981-nokia-ea0326gmp-config-utils.tar.gz
mv mkconfig seama /bin
chmod +x /bin/mkconfig
chmod +x /bin/seama
5. Decrypt and uncompress the configuration:
Enter fakeroot if you are not login as root.
mkconfig -a de-enca -m EA0326GMP_3FE79221BAAA -i EA0326GMP_3FE79221BAAA-xxxxxxxx-backup.tar.gz -o backup.tar.gz
tar -zxf backup.tar.gz
6. Edit 'etc/config/dropbear', set 'enable' to '1'.
7. Edit `etc/passwd`, remove root password: 'root::1:0:99999:7:::'.
8. Repack the configuration:
tar -zcf backup.tar.gz etc/
mkconfig -a enca -m EA0326GMP_3FE79221BAAA -i backup.tar.gz -o EA0326GMP_3FE79221BAAA-xxxxxxxx-backup.tar.gz
9. Upload new configuration via web interface, now you can SSH to EA0326GMP.
A minimum configuration which enabled SSH access is also provided to simplify the process:
https://firmware.download.immortalwrt.eu.org/cnsztl/mediatek/filogic/openwrt-mediatek-mt7981-nokia-ea0326gmp-enable-ssh.tar.gz
Flash instructions:
1. SSH to EA0326GMP, backup everything, especially 'Factory' part.
2. Write new FIP provided by https://github.com/hanwckf/bl-mt798x.
3. Reboot, enter web failsafe and upload -factory.bin firmware.
