This makes a strong assumption on the ordering and is not very flexible since only a limited set of flash devices can be defined : 1 FMC + 1 or 2 SPI, which is less than what the SoC really supports. A better alternative would be to define the flash devices on the command line using a blockdev attached to a CS line of a SSI bus : -blockdev node-name=3Dfmc0,driver=3Dfile,filename=3D./flash.img -device mx66u51235f,addr=3D0x0,bus=3Dssi.0,drive=3Dfmc0 However, user created flash devices are not correctly wired to their SPI controller and consequently can not be used by the machine. Fix that and wire the CS lines of all available devices when the SSI bus is reset.

See routine connect_serial_hds_to_uarts(). Nevertheless, some machines use another boot console, such as the fuji, and commit 5d63d0c76c ("hw/arm/aspeed: Allow machine to set UART default") introduced a SoC class attribute 'uart_default' and property to be able to change the boot console device. It was later changed by commit d2b3eaefb4 ("aspeed: Refactor UART init for multi-SoC machines"). The "uart" machine option goes a step further and lets the user define the UART device from the QEMU command line without introducing a new machine definition. For instance, to use device UART3 (mapped on /dev/ttyS2 under Linux) instead of the default UART5, one would use : -M ast2500-evb,uart=3Duart3 Cc: Abhishek Singh Dagur Signed-off-by: C=C3=A9dric Le Goater --- docs/system/arm/aspeed.rst | 10 ++++++++++ hw/arm/aspeed.c | 39 ++++++++++++++++++++++++++++++++++++-- 2 files changed, 47 insertions(+), 2 deletions(-) diff --git a/docs/system/arm/aspeed.rst b/docs/system/arm/aspeed.rst index d4e293e7f9..e70f0aeea3 100644 --- a/docs/system/arm/aspeed.rst +++ b/docs/system/arm/aspeed.rst @@ -122,6 +122,10 @@ Options specific to Aspeed machines are : =20 * ``spi-model`` to change the SPI Flash model. =20 + * ``uart`` to change the default console device.
