* 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.
Support optional board specific default RPi firmware configuration file
(config.txt). Also rename from boot-env.txt to config.txt since this
file is not read by the U-Boot boot loader but the Raspberry Pi specific
boot firmware.
* add eq3_char_loop package (eQ-3 char loopback kernel module)
* add generic_raw_uart package (low-latency raw UART kernel driver)
* add rpi-rf-mod package
* add device tree overlay support for RPI-RF-MOD/HM-MOD-RPI-PCB on Raspberry Pi
* enable GPIOLIB and GPIO_SYSFS required for RPI-RF-MOD/HM-MOD-RPI-PCB support.
* add basic RPI-RF-MOD/HM-MOD-RPI-PCB support for ASUS Tinker Board
* add device tree overlay support for ASUS Tinker Board and add
haos-config.txt loading support to U-Boot boot script
* Add 2020-10-28 beta EEPROM
This improves boot from USB and speeds up boot times.
also includes sd card v1 boot reliability.

Also add HDMI_DELAY=0 so HDMI display is always visible
for easier debugging.
