Flashing Bootloader and firmware to Creality Ender 2
Built AVRDude with initial support from the repository, https://github.com/maxxproff/avrdude-ch341.git
Only built with ch341a support and not bitbang using SPI on my atmega1842p clocked at 16Mhz, the bitbang support
requires linking to a library not compatible with Linux Aarch64, and I don't need it.
Grabbed optiboot firmware from the Sanguino project, https://github.com/Lauszus/Sanguino/blob/master/bootloaders/optiboot/optiboot_atmega1284p.hex
./avrdude -p atmega1284p -c ch341a -C avrdude.conf -e -u -U lock:w:0x3f:m -U efuse:w:0xFD:m -U hfuse:w:0xDE:m -U lfuse:w:0xFF:m
./avrdude -p atmega1284p -c ch341a -C avrdude.conf -e -u -U flash:w:optiboot_atmega1284p.hex -U lock:w:0x0f:m
Then built TH3D_Unified2_Creality_Melzi with Microsoft Visual Code for Linux Aarch64 and optiplex
and flashed the firmware over usbserial with the following command.

Subject: [PATCH] drm/amd/display: Re-enable Arm64 support for Navi and newer
GPUs
This is a WIP patch working on enabling Navi and newer support
for Arm64. It requires breaking out all code that use floating point
and compiling those targets with -mgeneral-regs-only. Then all the
calling targets or called functions are wrapped in DC_FP_START()

Subject: [PATCH] Aarch64: Make memcpy more compatible with device memory
For normal non-cacheable memory ACE supports 4x128 bit r/w WRAP
transfers or 1x128 bit r/w INCR transfers. By re-ordering the
stp's in memcpy / memmove we can accomodate this better without
impacting the existing code.
