This moves the double fault data used at boot time into a single struct which can then easily be addressed with indexed loads rather than having to explicitly load multiple addresses. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

During very early init, the stack pointer is given a slightly incorrect value (&init_thread_union). The value is later adjusted to the right one during early init (&init_thread_union + THREAD_SIZE), but it is used a few times in between. While the few functions used don't actually put things onto the stack (due to optimization), it's best if we simply use the right value from the start.

Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).

Since the hardware only provides reporting for the last exception handled, and the values are valid only when executing the exception handler, we need to save the context for reporting at a later point. While we do this for one exception, it doesn't work properly when handling a second one as the original exception is clobbered by the double fault. So when double fault debugging is enabled, create a dedicated shadow of these values and save/restore out of there. Now the crash report properly displays the first exception as well as the second one. Signed-off-by: NGraf Yang <graf.yang@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Allow hardware errors to be caught during early portions of booting, and leave something in the shadow console that people can use to debug their system with (to be printed out by the bootloader on next reset). This enables the hardare error interrupts in head.S, allowing us to find hardware errors when they happen (well, as much as you can with a hardware error) and prints out the trace if it is enabled. This will catch errors (like booting the wrong image on a 533) which previously resulted in a infinite loop/hang, as well as random hardware errors before before setup_arch(). To disable this debug only feature - turn off EARLY_PRINTK. Signed-off-by: NRobin Getz <robin.getz@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Commit 6b3087c6 (which introduced Blackfin SMP) broke command line passing when the DEBUG_DOUBLEFAULT config option was enabled. Switch the code to using a scratch register and not R7 which holds the command line. Signed-off-by: NMike Frysinger <vapier@gentoo.org>
