From 76c03152e110dcb770253b54277811228e8f78df Mon Sep 17 00:00:00 2001 From: Amaan Cheval Date: Mon, 9 Jul 2018 16:42:56 +0530 Subject: bsp/x86_64: Minimal bootable BSP Current state: - Basic context initialization and switching code. - Stubbed console (empty functions). - Mostly functional linker script (may need tweaks if we ever want to move away from the large code model (see: CPU_CFLAGS). - Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for UEFI-awareness. In short, the current state with this commit lets us boot, go through the system initialization functions, and then call user application's Init task too.
