hw/arm/aspeed: Add machine properties to define the flash models
Some machines don't have much differences a part from the flash model being used. Introduce new machine properties to change them from the command line. For instance, to start the ast2500-evb machine with a different FMC chip and a 64M SPI chip, use : -M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f Cc: 郁雷 <yulei.sh@bytedance.com> Reviewed-by: Joel Stanley <joel@jms.id.au> Tested-by: Lei YU <yulei.sh@bytedance.com> Message-Id: <20200915054859.2338477-1-clg@kaod.org> Signed-off-by: Cédric Le Goater <clg@kaod.org>

+Options specific to Aspeed machines are :

+ * ``execute-in-place`` which emulates the boot from the CE0 flash
+ device by using the FMC controller to load the instructions, and
+ not simply from RAM. This takes a little longer.

+ * ``fmc-model`` to change the FMC Flash model. FW needs support for
+ the chip model to boot.
+
+ * ``spi-model`` to change the SPI Flash model.

+For instance, to start the ``ast2500-evb`` machine with a different
+FMC chip and a bigger (64M) SPI chip, use :
