Jimmy Huang c159a0ec4a arm64: mmu: Prevent CPU prefetch instructions from device memory
Set XN bit of block upper attribute to device memory in mmu. CPU may
speculatively prefetch instructions from device memory, but the IO
subsystem of some implementation may not support this operation. Set
this attribute to device memory mmu entries can prevent CPU from
prefetching device memory.

Julius Werner 4bfa29e947 arm64: xcompile: Add support for A53 erratum 843419
This patch adds support to enable a linker workaround to a hardware
erratum on some early Cortex-A53 revisions. Since the linker option was
added very recently, we use xcompile to test whether the toolchain
supports it first. It is also guarded by a Kconfig since only a few
ARM64 SoCs will need this and it incurs a performance penalty.

Julius Werner 623368113c arm64: Decouple MMU functions from memranges
The current arm64 MMU interface is difficult to use in pre-RAM
environments. It is based on the memranges API which makes use of
malloc(), and early stages usually don't have a heap. It is also built
as a one-shot interface that requires all memory ranges to be laid out
beforehand, which is a problem when existing areas need to change (e.g.
after initializing DRAM).

The long-term goal of this patch is to completely switch to a
configure-as-you-go interface based on the mmu_config_range() function,
similar to what ARM32 does. As a first step this feature is added
side-by-side to the existing interface so that existing SoC
implementations continue to work and can be slowly ported over one by
one. Like the ARM32 version it does not garbage collect page tables that
become unused, so repeated mapping at different granularities will
exhaust the available table space (this is presumed to be a reasonable
limitation for a firmware environment and keeps the code much simpler).

Also do some cleanup, align comments between coreboot and libpayload for
easier diffing, and change all error cases to assert()s. Right now the
code just propagates error codes up the stack until it eventually
reaches a function that doesn't check them anymore. MMU configuration
errors (essentially just misaligned requests and running out of table
space) should always be compile-time programming errors, so failing hard
and fast seems like the best way to deal with them.

BRANCH=None
BUG=None
TEST=Compile-tested rush_ryu. Booted on Oak and hacked MMU init to use
mmu_config_range() insted of memranges. Confirmed that CRCs over all page
tables before and after the change are equal.

Patrick Georgi b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Aaron Durbin 9425a545d7 libpayload arm64: fix mmu bugs
1. keep functions and objects used entirely within mmu.c as static.
2. DMA region finding needs to terminate. Therefore, the next address
   to be attempted needs to be less then the current end address.
3. Ensure mmu_ranges passed to mmu_init_ranges_from_sysinfo() has
   0 entries marked as used.

Furquan Shaikh 39292638af libpayload arm64: Initialize and enable MMU
What this change does:
1) Initialize limited page tables as soon as we jump into libpayload. Basically
two ranges are initialized. One is for the BASE_ADDRESS and other is for the
coreboot_tables. With page tables initialized and MMU enabled, we jump into
code to parse coreboot tables.
2) Once coreboot tables are parsed and we have complete picture of the memory,
we perform a complete page table initialzation and enable MMU and then jump to
payload.

Additionally, we also:
1) Initialize DMA memory on our own depending upon the memory map. It ensures
that the DMA buffer is placed in 32-bit memory.

Vadim Bendebury 864ec8c488 libpayload: Consolidate coreboot table parsing
There are three instances of coreboot.c in libpayload. for x86, arm
and arm64 architectures. The arm and arm64 instances are exactly the
same. The differences with the x86 instance are as follows:

 - a very slightly different set of coreboot table tags is parsed (one
   tag added and two removed)

 - instead of checking a fixed address if it contains the coreboot
   table, the x86 version iterates over two address ranges.

This patch refactors the module, leaving architecture specific
processing in arch subdirectories and moving the common code into
libc.

Julius Werner 092cac58de libpayload: Rework exception hook interface
This patch makes some slight changes to the exception hook interface.
The old code provides a different handler hook for every exception
type... however, in practice all those hook functions often need to look
very similar, so this creates more boilerplate than it removes. The new
interface just allows for a single hook with the exception type passed
as an argument, and the consumer can signal whether the exception was
handled through the return value. (Right now this still only supports
one consumer, but it could easily be extended to walk through a list of
hooks if the need arises.)

Also move the excepton state from an argument to a global. This avoids a
lot of boilerplate since some consumers need to change the state from
many places, so they would have to pass the same pointer around many
times. It also removes the false suggestion that the exception state was
not global and you could have multiple copies of it (which the exception
core doesn't support for any architecture).

On the ARM side, the exception state is separated from the exception
stack for easier access. (This requires some assembly changes, and I
threw in a few comments and corrected the immediate sigils from '$' to
the official '#' while I'm there.) Since the exception state is now both
stored and loaded through an indirection pointer, this allows for some
very limited reentrance (you could point it to a different struct while
handling an exception, and while you still won't be able to return to
the outer-level exception from there, you could at least swap out the
pointer and return back to System Mode in one go).

BUG=chrome-os-partner:18390
TEST=Made sure normal exceptions still get dumped correctly on both
archs.

libpayload: align arm64 with new exception handling model

The exception handling was previously updated, however the
arm64 changes raced with hat one. Make the arm64 align with
the new model. Without these changes compilation will fail.

BUG=None
BRANCH=None
TEST=Can build libpayload for rush.
