58e5585625 sparc: leon3: Clear GD_FLAG_SERIAL_READY flag on AMBA failure
Clear the GD_FLG_SERIAL_READY flag on AMBA P&P lookup failure so that the
panic function can use DEBUG_UART driver. drivers/serial/serial.c set this
flag before calling this function, preventing DEBUG_UART code from running.

a50adb7b4d sparc: Update LEON serial drivers to use readl/writel macros
Update the LEON2/3 serial driver to make use of the readl and writel
macros as well as the WATCHDOG_RESET() macro.

Add readl/writel and friends to the asm/io.h file.

Introduce the gd->arch.uart variable to store register address.

Lastly, remove baudrate scaler macro variables from board config. It
is now calculated in the serial driver using the global data variable.

These macros are already defined in io.h so should not be declared in
serial.c.

ec3fd68952 serial: Use default_serial_puts() in drivers
Replace the in-place ad-hoc implementation of serial_puts() within
the drivers with default_serial_puts() call. This cuts down on the
code duplication quite a bit.

a382725060 serial: Remove CONFIG_SERIAL_MULTI from serial drivers
Remove the support for not-CONFIG_SERIAL_MULTI part from serial
port drivers and some board files. Since CONFIG_SERIAL_MULTI is
now enabled by default, that part is a dead code. Remove it.

29b5ff7f8e serial: sparc: Implement CONFIG_SERIAL_MULTI into leon3 serial driver
Implement support for CONFIG_SERIAL_MULTI into leon3 serial driver.
This driver was so far only usable directly, but this patch also adds
support for the multi method. This allows using more than one serial
driver alongside the leon3 driver. Also, add a weak implementation
of default_serial_console() returning this driver.
