arm: adjust PC displayed in exception handlers to point to the failing instruction

2017-06-12T12:38:39+00:00

Adjust the program counter register to point to the failing
instruction depending on the exeption type.
This makes it easier to localize the offending instruction leading to
a fatal exception.

Remove various unused interrupt related code

2017-04-07T00:42:18+00:00

With d53ecad92f06 some unused interrupt related code was removed.
However all of these options are currently unused.  Rather than migrate
some of these options to Kconfig we just remove the code in question.

The only related code changes here are that in some cases we use
CONFIG_STACKSIZE in non-IRQ related context.  In these cases we rename
and move the value local to the code in question.

arm: Allow EFI payload code to take exceptions

2016-03-16T01:30:13+00:00

There are 2 ways an EFI payload could return into u-boot:

  - Callback function
  - Exception

While in EFI payload mode, r9 is owned by the payload and may not contain
a valid pointer to gd, so we need to fix it up. We do that properly for the
payload to callback path already.

This patch also adds gd pointer restoral for the exception path.

arm: Show relocated PC/LR in the register dump

2015-02-03T17:42:01+00:00

If we don't know the relocation address, the raw values are not very useful.
Show the pre-relocation values as well as these can be looked up in
System.map, etc.

arm: interrupt_init: set sp in IRQ/FIQ modes

2014-10-29T13:03:28+00:00

Before this commit, the stack addresses for IRQ and FIQ modes,
IRQ_STACK_START and FIQ_STACK_START, were computed in interrupt_init but
they were not used.

This commit sets the stack pointers for IRQ and FIQ modes.

ARM: add missing HYP mode constant

2014-07-28T15:06:35+00:00

In order to be able to use the various mode constants (far more
readable than random hex values), add the missing HYP and A
values.

Also update arm/lib/interrupts.c to display HYP instead of an
unknown value.

arm: Switch to -mno-unaligned-access when supported by the compiler

2014-02-26T20:19:32+00:00

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level.  We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.

To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.
