For sparc/sparc64, there are CONFIG_ symbols which are undefined.
On sparc64, CONFIG_AGP and CONFIG_AGP_INTEL are undefined.
On sparc, CONFIG_I2C, CONFIG_I2C_ALGOBIT, CONFIG_AGP, CONFIG_AGP_INTEL,
CONFIG_VIDEO_DEV, and CONFIG_ISP1301_OMAP are undefined.
This causes errors like "config:1234: trying to assign nonexistent
symbol FOO" to be thrown when the kernel config tools are run.
The reason that these CONFIG_ symbols are undefined is because the
hardware isn't supported by sparc/sparc64, but other supported hardware
resides in the same .config files pulled in by the various driver
Kconfig files.
Rather than hacking up the driver Kconfig files, I've created a new
arch-specific Kconfig.undefined file, where these (and future) undefined
symbols can be added for sparc/sparc64. This Kconfig.undefined file is
sourced by arch/{sparc,sparc64}/Kconfig, before the driver Kconfigs are
sourced.
The end result is that the undefined CONFIG_ symbol errors are not
thrown when the config utilities are run. The errors are not fatal, but
they do cause confusion when users are building kernels for
sparc/sparc64.
