Subject: uboot: Deprecate legacy UBOOT_CONFIG flow
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=60c62c4de3f176b92912143a80dc1b160a5a0682;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

uboot: Deprecate legacy UBOOT_CONFIG flow

Mark the legacy flow for settings the UBOOT_CONFIG options in a comma
separated list.  This code will still work through wrynose, but will be
removed once wrynose is released.

Add warnings to point people in the right direction for fixing their
configs:

WARNING: Legacy use of UBOOT_CONFIG[foo] = "foo_config,foo_image,foo_binary" is deprecated.  Please move to using UBOOT_CONFIG_* variables:
WARNING:     UBOOT_CONFIG[foo] = "foo_config"
WARNING:     UBOOT_CONFIG_IMAGE_FSTYPES[foo] = "foo_image"
WARNING:     UBOOT_CONFIG_BINARY[foo] = "foo_binary"
WARNING: Legacy use of UBOOT_CONFIG[bar] = "bar_config,bar_image" is deprecated.  Please move to using UBOOT_CONFIG_* variables:
WARNING:     UBOOT_CONFIG[bar] = "bar_config"
WARNING:     UBOOT_CONFIG_IMAGE_FSTYPES[bar] = "bar_image"
WARNING: Legacy use of UBOOT_CONFIG[bing] = "bing_config,,bing_binary" is deprecated.  Please move to using UBOOT_CONFIG_* variables:
WARNING:     UBOOT_CONFIG[bing] = "bing_config"
WARNING:     UBOOT_CONFIG_BINARY[bing] = "bing_binary"
