Similar to pinky, brain is a development model and probably also
nearing extinction. But to keep pinky from being lonely I'll keep
the two brain boards around as well, especially as they as well
have easily accessible dut-connectors.

The edp-24m clock has two possible sources: the 24MHz oscillator as well
as an external 27MHz input. The power-on-default is the 27MHz clock which
is not supplied on all Rockchip boards. While on all current boards and
also all Veyron Chromebooks the bootloader seems to adapt the muxing to
the internal source, this doesn't seem to be the case on headless veyron
devices like brain and mickey making the edp-24m clock an orphan.
On the hardware side the 27m input also is not connected at all.

With the upcoming deferral of orphan-clocks this results in the power-
domain code deferring, as it cannot request the needed clock and if the
synchronous reset is sucessfullat all in this case is also unknown.

So fix that by making sure, the edp-24m clock is muxed to the internal
24MHz oscillator at all times.

cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per

unconditionally.

ARCompact and ARCv2 only have ASL, while binutils used to support LSL as

Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)

 - So move mem_service exception handler from common code into ARCv2 code.
 - In ARCompact code, define  mem_service as L2 interrupt handler which
   just drops down to pure kernel mode and goes of to enqueue SIGBUS

While mips can't use the generic compat_siginfo_t directly because
its si_code and si_errno are inverted, we can still make it as
close to the generic version as possible. This makes it easier
to update when new members are added to siginfo_t.

The main changes are adding a missing _sigsys union member and
eliminating the unused _irix_sigchld one.

Similar to how arm allows using selecting between bootloader arguments,
dtb arguments and both, allow to select them on mips. But since we have
less control over the place of the dtb do not modify it but instead use
the boot_command_line for merging them.

The default is "use bootloader arguments" to keep the current behaviour
as default.
