The BR2_GCC_ENABLE_LTO config used to enable LTO on compiler level. That
config symbol doesn't exist anymore. Instead, LTO is enabled by default
with GCC.
However, there is a new flag named BR2_ENABLE_LTO which enables LTO in
packages. So far it doesn't look like that packages we are using support
the flag, but that might get added in the feature. Opt-in already today.
Home Assistant Green uses a SPI NOR flash storage. One can use dd to
write to the SPI NOR flash, but this is problematic if a unit has bad
blocks. Add MTD tools, specifically flashcp, to enable SPI NOR
flashing support.
Update U-Boot board configuration for Home Assistant Green. This moves
all Green specific board configuration into the U-Boot source code
patches. The "sf probe" command now picks up the correct SPI bus by
default.
* Initial commit of Home Assistant Green board support
* Add Home Assistant Green boot files
* HA Green board configs
* board/nabucasa: Unsupport rtc rk808
* Use odroid-m1 as Supervisor machine for now
* Green: linux: pmic: set set PWRON_LP_OFF_TIME 12s
* green: Update U-Boot to 2023.07.02
* green: supports usb boot
* green: uboot-boot.ush use rk3566-ha-green.dtb
* green: spinor supports uboot
* green: use U-Boot provided devtype as boot device type
* green: Fix polarity of power key
The power key is low active. Add patch to avoid accidential long press
being reported to user space.
* green: uboot: eeprom: add CONFIG_ENV_OVERWRITE
* green: uboot: eerprom: add mac read
* green: fix-cpufreq null issue
* green: board aliases ethernet0
* green: uboot mac set ethernet0
* green: uboot add serial-number read
* green: Update kernel 6.1.39
* green: add green to the build matrix
* green: fix 339d13 & 9b9416 can not boot from usb
* green: changfe sd mode, change led default state
* green: uboot add board.c to read eeprom info
* green: enable uboot to read eeprom info
* green: delete boot.scr read eeprom function
* green: change spl loader uboot order:sd-emmc-spi_nor
* green: serialnum change to 18 bytes
* green: Update kernel 6.1.43
* green: use hwrng support from ODROID-M1
* green: Use latest Rockchip BL31/DDR binaries
* change led_act polarity
* green: Disable watchdog
The watchdog on Green seems to not reliably reset the system. For now
disable the driver to avoid systemd making use of it.
* green: Update kernel 6.1.44
* green: Fix Supervisor Machine
Use odroid-m1 for now as Supervisor machine (used to download the
landing page).
* green: emmc use hs200 to increase speed
* green: use green as Supervisor machine
* green: Update kernel 6.1.45
* green: add Green to the kernel documentation

Use the official rkbin repository for Rockchip binaries. Use the
binaries from an older git hash which provide the very same binaries
(by hash). This makes sure we use the same DDR version as currently used
by the Hardkernel in their SPI flash bootloader (DDR v1.09).
* Including the RTW8821ce driver module to support Wifi on the KAMRUI AK1 PRO micro PC. It is a low-cost Intel Celeron N5105 that I think should work well for Home Assistant. However, it does not use Intel radios, it needs Realtek drivers.
* also need the firmware for the rtl8821ce
* Yellow: Always use mini-UART for Bluetooth
Unfortunately, the mini-UART device tree adjusts the alias for serial1,
which we need to make ttyAMA1 the Zigbee UART (UART4).
However, we can no simply adjust that overlay, as the overlays are not
built as part of the Buildroot build. Instead, they are directly copied
from Raspberry Pi's Firmware repostiory.
Instead of using device tree overlays, just apply the changes to our
Yellow specific device tree. To avoid that the device tree gets loaded
anyhow, we could adjust config.txt but that has complications on its
own. Since the overlay might be conflicting with the Yellow device tree
anyways, just remove all of them.
Note: The miniuart-bt.dtbo overlay won't be present, while config.txt
of upgraded instances still reference it. It seems that this doesn't
cause problems at boot time. Leaving the dtoverlay=miniuart-bt present
also allows user to downgrade in case needed.
* Avoid duplicating 98-rpi.conf
