Which microcode patch for MPC870?

[Shawn Jin <shawnxjin@gmail.com>]

Hi,

Which microcode patch should be selected for MPC870? In the old 2.4
kernel, the CONFIG_UCODE_PATCH was selected. What's the corresponding
config: CONFIG_USB_SOF_UCODE_PATCH or CONFIG_I2C_SPI_UCODE_PATCH or
CONFIG_I2C_SPI_SMC1_UCODE_PATCH? Since my board doesn't have USB, I
believe USB microcode is irrelevant here. So it comes down the other
two choices. Of course do I really need the patch? My board has I2C
and SMC1, but no SPI.

I chose CONFIG_I2C_SPI_UCODE_PATCH as an experiment but got the
following compilation error:
  CC      arch/powerpc/sysdev/micropatch.o
arch/powerpc/sysdev/micropatch.c: In function 'cpm_load_patch':

arch/powerpc/sysdev/micropatch.c:629: error: 'spp' undeclared (first

arch/powerpc/sysdev/micropatch.c:629: error: (Each undeclared

arch/powerpc/sysdev/micropatch.c:630: warning: unused variable 'smp'
make[1]: *** [arch/powerpc/sysdev/micropatch.o] Error 1

Obviously there is no spi_t declaration in 2.6.33.5. So where is this
spi_t declared?

Thanks a lot,
