[PATCH v2 07/18] aspeed: Fix hardcode attach flash model of spi controllers
Posted by Jamin Lin via 1 year, 3 months ago
It only attached flash model of fmc and spi[0] in aspeed_machine_init function.
However, AST2500 and AST2600 have one fmc and two spi(spi1 and spi2)
controllers; AST2700 have one fmc and 3 spi(spi0, spi1 and spi2) controllers.

Besides, it used hardcode to attach flash model of fmc, spi[0] and spi[1] in
aspeed_minibmc_machine_init for AST1030.

To make both functions more flexible and support all ASPEED SOCs spi
controllers, adds a for loop with sc->spis_num to attach flash model of
all supported spi controllers. The sc->spis_num is from AspeedSoCClass.

oops. R-b sent on the wrong patch.

To be honest, I am not a big fan of the aspeed_board_init_flashes()
routine. See commit 27a2c66c92ec for the reason.

I prefer the more flexible approach :

$ qemu-system-arm -M ast2600-evb \
       -blockdev node-name=fmc0,driver=file,filename=/path/to/fmc0.img \
       -device mx66u51235f,bus=ssi.0,cs=0x0,drive=fmc0 \
       -blockdev node-name=fmc1,driver=file,filename=/path/to/fmc1.img \
       -device mx66u51235f,bus=ssi.0,cs=0x1,drive=fmc1 \
       -blockdev node-name=spi1,driver=file,filename=/path/to/spi1.img \
       -device mx66u51235f,cs=0x0,bus=ssi.1,drive=spi1 \
       -nographic -nodefaults

which doesn't use the drive_get() interface and so, doesn't make
assumption on the order of the drives defined on the QEMU command
line.

Also, the number of availabe flash devices is a machine definition,
not a SoC definition. Not all CS are wired.

I will drop that patch for now.


Thanks,

C.

Thanks for notify me this solution.
I can successfully attach the default image to supported SPI controllers with different flash model.
It seems we need to add "defaults_enabled()" if-statement in aspeed_minibmc_machine_init
to support this solution for AST1030. Otherwise, I will get this error.

qemu-system-arm: -device w25q80bl,bus=ssi.0,cs=0x0,drive=fmc0: CS index '0x0' in use by a w25q80bl device

https://github.com/qemu/qemu/blob/master/hw/arm/aspeed.c 
 if (defaults_enabled()) {
  aspeed_board_init_flashes(&bmc->soc->fmc,
                              bmc->fmc_model ? bmc->fmc_model : amc->fmc_model,
                              amc->num_cs,
                              0);

  aspeed_board_init_flashes(&bmc->soc->spi[0],
                              bmc->spi_model ? bmc->spi_model : amc->spi_model,
                              amc->num_cs, amc->num_cs);

    aspeed_board_init_flashes(&bmc->soc->spi[1],
                              bmc->spi_model ? bmc->spi_model : amc->spi_model,
                              amc->num_cs, (amc->num_cs * 2));
  }

Do I need to send this patch in v3 patch series?
Or individually send this patch in the new patch series?
