Add MXS bootlets package
MXS platforms (imx23 and imx28) are relying on bootlets as their first stage bootloaders, that can then either start a regular second stage bootloader or directly a Linux kernel. However, the Makefile allows only to build u-boot and linux images at the same time, which is not very convenient as we will more likely use only one of them, so we need to duplicate a bit what is already done so that we are able to choose what we want to generate. thomas.petazzoni@free-electrons.com: * Remove incorrect dependency on BR2_PACKAGE_ELFTOSB * Each board configuration option is for one board, not multiple boards, so use singular. * The i.MX28 support is for i.MX28 EVK only, reflect that in the option prompt and the option name. * Use 'generic-package' instead of GENTARGETS Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
