Hello !

Thanks for those patches. A few comments below.

If I understood correctly ccid is a set of programs that depends on
pcsc-lite which is a library ? If this is the case, then you should
turn this into :

	select BR2_PACKAGE_PCSC_LITE

This is because we prefer to have automatic selection of required
dependencies.

> +	bool "ccid"
> +	help
> +		Card reader driver

The help message should be intended with one tab + 2 spaces. The
description could also be a little bit more elaborate (which type of
hardware is supported, etc.). And we typically include the URL of the
project. See other packages for examples.

> +##########################################################

> +# CCID
> +#
> +# ########################################################
> +CCID_VERSION = 5706
> +CCID_SITE = svn://anonscm.debian.org/pcsclite/trunk/Drivers/ccid

The latest ccid release is 1.4.4, dated May 2011, which doesn't seem to
be that old. In general, we prefer using stable releases rather than
SVN versions when possible. Do you have a good reason for choosing a
specific SVN version instead of the latest project release ?

If you depend on libusb here, then the CCID package should also:

	select BR2_PACKAGE_LIBUSB

> +$(eval $(call AUTOTARGETS, package, ccid))

Is it pcsc that depends on ccid, or ccid that depends on pcsc ?
According to your *_DEPENDENCIES variable, it's ccid that depends on
pcsc-lite, so the "select BR2_PACKAGE_CCID" here should go away.

Same comment as above: indentation is tab + 2 spaces, more elaborate
description, and project URL.

Same question, SVN version really needed ?

> +PCSC_LITE_INSTALL_STAGING = YES
> +PCSC_LITE_INSTALL_TARGET = YES
> +PCSC_LITE_AUTORECONF = YES
> +PCSC_LITE_CONF_OPT = --disable-libudev --enable-libusb
> --enable-embedded +PCSC_LITE_DEPENDENCIES=libusb

> +$(eval $(call AUTOTARGETS, package, pcsc-lite))

Again, thanks for proposing those two packages!
