KASLR, or Kernel Address Space Layout Randomization, is a
security mechanism used in operating system kernels to randomize
the memory locations of kernel code and data. This makes it
significantly harder for attackers to exploit memory corruption
vulnerabilities by preventing them from knowing the exact
addresses of kernel components.

BPI-CM4:
In accordance with the BSP DTS, set LED gpio to GPIO_ACTIVE_LOW.
Added default-on trigger to led-green
Board now powers off, added reboot node 'meson64-reboot'.
CONFIG_POWER_RESET_MESON64
Isolated RESET ODROID driver and renamed to MESON64 as it can be used in more than ODROIDS.
MESON UART
Series improves support for UART attached Bluetooth modules on Amlogic Meson G12A and newer SoCs. These SoCs also support the "divide XTAL by 2" bit which (greatly) reduces jitter when generating baud rates such as 1500000 (which is used by the Bluetooth part of the RTL8822CS SDIO WiFi and UART Bluetooth combo chip).

- `meson64`-`edge` (6.2.y): drop old/unused/pre-armbian-next builddeb patch that was leftover
- `meson64`-`edge` (6.2.y): pick & squash from chewitt's tree; new t95z board and its tm1628 driver, fixes for odroidc2, vim3, gxl/gxm SDIO
- `meson64`-`edge` (6.2.y): reword the `-spi` extra DTBs for the N2(+) into more generic for g12; add VIM3/VIM3L which also have same SPI NOR scheme
- `meson64`-`edge` (6.2.y): update .config to 6.2.16; enable `CONFIG_TM1628`
- `meson64`-`edge` (6.2.y): rebase to 6.2.16 after picking chewitt
This is already enabled in the rockchip family on edge and per the discussion
here: https://forum.armbian.com/topic/20018-mglru-patches-to-bring-down-kswapd-cpu-usage
I would like to enable it on meson64-edge. And if that goes smoothly,
I will followup with a PR to enable it on meson64-current also since that is
now on 6.1.
Changes to be committed:
modified: config/kernel/linux-meson64-edge.config
config doesn't include rtl8822cs (which apparently some TV boxes use).
This is enabled in most kernel configs:

This commit enables this for just the meson64-edge kernel as that resolves the
issue I was researching, but I suspect it probably should also be enabled for
rockchip-edge as well, but I don't have any such devices.
On branch rtl8822cs_meson64_edge
Changes to be committed:
modified: ../kernel/linux-meson64-edge.config
* Remove deprecated Odroid XU4 legacy 4.14.y branch
* Clean deprecated kernels from meson64 family
- legacy kernel 4.9 was removed
- current 5.10 was replaced with 5.19
- edge remains on 5.19 until someone bumps it to 6
- patches between 5.11 and 5.18 were removed, 5.10 will be kept for awhile
* Update configs
* meson64-edge/5.19: use `tag:v5.19-rc2`, meson64 kernel config and kernel patches, by @adeepv
* meson64-edge/5.19: we don't need `CONFIG_ARCH_ROCKCHIP=y` for meson64, right?
* meson64-edge/5.19: remove `meson_drv_shutdown` revert patch, instead `CONFIG_DRM_MESON=y` and its dependencies in .config
- this allows other meson64's to shutdown properly, while allowing the N2(+) to reboot without kernel-side hangs
* meson64-edge/5.19: odroidn2(+): remove SD UHS modes patch for ODROID N2(+)
- it works when cold-booted
- but changes voltage to enable
- when rebooted, voltage persists and uboot can't read the SD anymore
- adding the "odroid,reboot" driver+dt that is supposed to fix this, doesn't
- so for now remove it
* meson64-edge/5.19: odroidn2(+): add dumb gpio fan at 30 celsius
- backport from rework in 5.10
* meson64-edge/5.19: odroidhc4: bring back `fan1_input` by adding fan details to DT
- yeah, I know; the cooling map is right there too, so empty, poor thing. for later.
* meson64-edge/5.19: bump to 5.19-rc3
* meson64-edge/5.19: radxa-zero: add patch to remove UHS mode so `wifi` works
- sent by @pyavitz: https://raw.githubusercontent.com/pyavitz/debian-image-builder/feature/patches/amlogic/radxazero/wifi/001-arm64-dts-amlogic-radxa-zero-sdio-card-speed.patch
- tested by @lanefu
* meson64-edge/5.19: bump to 5.19-rc4
* meson64-edge/5.19: bump to 5.19-rc5
* meson64-edge/5.19: bump to 5.19-rc7
* meson64-edge/5.19: bump to 5.19.y branch, which is 5.19.0 right now
* Add kernel config - tested on Odroid N2+

* rk35xx: enable the CONFIG_F2FS_FS_COMPRESSION option
This allows to use compression on a F2FS partition to save space and
reduce I/O operations to media.
* all: enable the CONFIG_F2FS_FS_COMPRESSION option
