Yes it's essentially a Zedboard. We used the standard Xilinx bsp as a starting
point and
then added drivers and functions of custom devices.

I just noticed there has been an update to a new Termios device driver a few
months ago.
Internally we don't update the tree very often that's why we still have the old
version.

Most of the core developers read the user list as well.
Looking at your first example it looks to me as if you forgot to reassign the
interrupt handlers.
Does it work if you change thinks like this:
zynq_uart_context zynq_uart_instances[2] = {
{
.base = RTEMS_TERMIOS_DEVICE_CONTEXT_INITIALIZER( "Zynq UART 0" ),
.regs = (volatile struct zynq_uart *) 0xe0001000,
//it was 0xe0000000,
.irq = ZYNQ_IRQ_UART_1 // Change from .irq = ZYNQ_IRQ_UART_0
}, {
.base = RTEMS_TERMIOS_DEVICE_CONTEXT_INITIALIZER( "Zynq UART 1" ),
.regs = (volatile struct zynq_uart *) 0xe0000000, //it was 0xe0001000,
.irq = ZYNQ_IRQ_UART_0 // Change from .irq = ZYNQ_IRQ_UART_1
}
};
