In b1fdf75/rtems:

bsp/tms570: Fix console receive interrupts

tms570_sci_interrupt_handler() is called when an RX interrupt fires. It checks
in the register FLR, the RXRDY bit (Receiver ready flag - indicate that the
SCIRD contains new data). If it is set, it calls
tms570_sci_read_received_chars().

tms570_sci_read_received_chars() checks the register RD against 0. If it is
non zero, it returns 1 to indicate that one byte was read.

In the old behavior, if it is zero, the function returns 0 to indicate that no
data was read.

The new behavior is to not silently drop 0x00 bytes. Ignoring 0x00 bytes is fine
when working with printable text (which, I assume, is how this driver was
tested), but as soon as the UART is used in non canonical (raw) mode, with
potentially 0x00 bytes, these bytes will be silently dropped, causing issues in
the data/protocol layer above.

Update #4982.
