- bool "PCI device name database"
- depends on PCI
- ---help---
- By default, the kernel contains a database of all known PCI device
- names to make the information in /proc/pci, /proc/ioports and
- similar files comprehensible to the user.
-
- This database increases size of the kernel image by about 80KB. This
- memory is freed after the system boots up if CONFIG_HOTPLUG is not set.

- 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.
