Hi,
The aarch64 bootm image handler for barebox can choose a load address
that is not 4KB aligned. This can result in unexpected behavior with
the ADRP instruction that is available in 64 bit ARM architectures.
ADRP forms a PC-relative address to a 4KB page where the bottom 12
bits of the current

Some RS485 serial interfaces does not use correctly RTS as Receiver
Enable and Data Enable, the internal receiver of the ns16550 must be
disabled during transmit to avoid loopback.
By default the option is enabled (when the property
'linux,rs485-enabled-at-boot-time' is present), and can be
Add possibility to use RTS signal as a Data Enable signal on RS485
transceivers.

The default ns16550 driver does not support rs485. This patchset adds
support for half duplex rs485 to the ns16550 driver. Basic handling of the RTS
signal is done to enable the rs485 transceivers.
Some properties are now parsed from the device tree:
- 'linux,rs485-enabled-at-boot-time', enabling
