There's an upstream change in cfg80211 that enables direct-loading of
wireless rules, which requires public key crypto in the kernel.  There
doesn't appear to be any option to disable that mode, even though we
don't need it because crda still works.  Maybe you could disable
wireless networking completely?

Some options that could possibly be changed from y to m:

- I2C, I2C_CHARDEV, I2C_MV64XXX.  initramfs-tools should include I2C
drivers to the initramfs if needed, but I'm not certain.

- MTD, MTD_CMDLINE_PARTS, etc.  But I'm pretty sure this will break
some systems unless initramfs-tools is updated to include and load the
cmdlinepart module.

- RTC_DRV_MV (and disable RTC_HCTOSYS).  There's a udev rule that
should load the system clock from the first RTC if its driver is a
module.

- SPI_ORION.  initramfs-tools should include this in the initramfs if
needed, but I'm not certain.

Some options that could possibly be disabled:

- AUDIT.  This is quite a niche feature.

Also try comparing the complete configs over time and looking for
symbols newly set to y.

Ben.
