This patch is required in case if you are using new toolchains. Best regards, Maxim Uvarov. From: Maxim Uvarov <muvarov@xxxxxxxxx> Linker does not provide some vital functions when building freestanding applications with a new toolchain, so we have to provide our own CRT. p.s. Without the CRT we won't see any build errors (since the purgatory is linked with --no-undefined), but the purgatory code won't work, 'kexec -e' will just hang the board. I added option to configure to keep code buildable for old toolchais. But there should be way to do this automatically.
