Linux v4.20-rc3 - drivers/zorro/Kconfig
# Zorro configuration
bool "Zorro device name database"
depends on ZORRO
By default, the kernel contains a database of all known Zorro device
names to make the information in /proc/iomem comprehensible to the
user. This database increases the size of the kernel image by about
15KB, but it gets freed after the system boots up, so it doesn't
take up kernel memory. Anyway, if you are building an installation
floppy or kernel for an embedded system where kernel image size
really matters, you can disable this feature and you'll get device
ID numbers instead of names.
When in doubt, say Y.
