The project at https://github.com/linux4sam/at91bootstrap was until now releasing 3.x versions, which were packaged using boot/at91bootstrap3/ in Buildroot. Microchip has now started a new branch of at91bootstrap, called 4.x, which will only support the following devices: sam9x60, sama5d2, sama5d3, sama5d4, sama7g5. A number of older devices from Microchip will only be supported by the existing 3.x series. Therefore, we cannot simply remove support for the 3.x series, and allow using only the 4.x series. So what this commit does is extend the boot/at91bootstrap3 package to support building both 3.x and 4.x versions. In detail, this implies: * Having the BR2_TARGET_AT91BOOTSTRAP3_LATEST_VERSION symbol point to the latest 4.x version. Indeed, we want BR2_TARGET_AT91BOOTSTRAP3_LATEST_VERSION to really point to the latest upstream version, even if that means potential breakage for users. Users who want to use a fixed version of at91bootstrap should anyway not be using BR2_TARGET_AT91BOOTSTRAP3_LATEST_VERSION. * Introduce BR2_TARGET_AT91BOOTSTRAP3_LATEST_VERSION_3X for users who would like to use the latest 3.x series. * Adjust the installation logic, as images to install are now in build/binaries/*.bin instead of binaries/*.bin. In order to not have to differentiate 3.x and 4.x, we simply use $(wildcard ...) to expand the list of files to install. * To make it clear that boot/at91bootstrap3 supports both 3.x and 4.x, we also update the prompt of the package. at911bootstrap does not carry a license file; so far we were using main.c as the license file, as it carries the license blurb. Now that we have a known alternate version, we would need a per-version hash for that file. However, this is a bit too cumbersome to handle, so just drop using main.c as the license file. When upstream introduces a proper license file, we can revisit the situation. Update the two defconfigs that were using the upstream 3.9.3 version; all other defconfigs are using custom tarballs or custom git trees.
