On non-x86 systems, the location of the preram CBMEM console may not be in a
predictable place relative to other things in the linker script. That makes it
difficult to work with as its own section because the linker will complain if
you try to move backwards as it lays out memory. If the console header is
treated as an actual blob of memory which has to be put in the image, we'd
have to predict where to put it so that it isn't before something with a lower
address or after something with a higher address. Symbols, on the other hand,
can be defined arbitrarily.

This patch fixes the remaining few bugs in our shiny new cache iteration
by set/way/level algorithm to actually make it work: It makes it start
from cache level 0 (previously it would always start at LoC and be
"done" instantly), fixes up the two shifts that isolate the set bits at
the end (which didn't seem to account for the fact that the first shift
affects the second), and throws an S bit on that last shift so that it
actually affects the conditionals after it.
In addition, also moves the next_level block to the top so that we can
share (and thus eliminate) some code at initialization, and turns the
whole thing into a thrice-instantiated macro to create functions that
fit our existing interface.

This patch pulls in NetBSD's full cache flushing algorithm for ARM, to
replace our old, slow and slightly overzealous C-only implementation.
It's a beautiful piece of code that manages to run on only caller-saved
registers (meaning it doesn't need to write to memory) in a very tight
loop, and it's BSD-licensed to boot (which we need for libpayload).
Unfortunately it's also not quite correct, but I can fix that. Pulling
the original in a separate commit to make it more obvious what changes
are mine.

The memcpy/memset/memmove assembly implementations have been taken from
U-Boot, which originally got them from Linux. I turns out that they are
actually not that bad, but they could use an update. This patch pulls in
the current Linux upstream versions of those files, removing some old
U-Boot cruft such as checking whether the two pointers in a memcpy() are
equal (really now?) or side-stepping the R8 register because it was used
for special purposes. It also returns to the good old Linux
ENTRY/ENDPROC macros since we have them now anyway, and straightens out
the W() macro in preparation for unified thumb support.

This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
mechanism is only useful to migrate variables from a special region
(e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
the romstage (it does not persist into ramstage). Since ARM devices use
SRAM for which there is no reason to become inaccessible in later parts
of the romstage, this mechanism isn't useful for them. Removing it makes
the romstage.ld script much simpler, which has the nice side-effect of
putting the BSS at the end of the memory image (so that cbfstool can
actually figure out that it doesn't need to be part of the ROM image).

This patch adds stub implementations of exception_init() to all archs
so that it can be called from src/lib/hardwaremain.c. It also moves/adds
all other invocations of exception_init() (which needs to be rerun in

likely overlooked when creating future boards. Also added (an
ineffective) one to the armv4 bootblock implementations for consistency
and in case we want to implement it later.

"Hey guys, I have this awesome idea! How about we put a huge array
filled with 0xa5 into the data segment of our uncompressed romstage

Guess it pays off to just hexdump our image and sanity-check it top to
bottom every once in a while...
Also reduces the size because 8K is crazy just to print a bunch of

arm: Remove exception_test()
The exception_test() mechanism might have been useful when exceptions
were first implemented, but now that they are pretty stable it's really
not necessary anymore (especially not on every single boot in production
Chromebooks). It forces a simple unaligned access, and as we start
having exceptions in stages that might not have paging turned on yet,
it's better to remove that completely.
Also removed the duplicated implementations of SCTLR-stuff and switched
to the existing ones in cache.h.

Add the option to coreboot to set the SeaBIOS buffers below 0xC0000.
This is a requirement on the Intel Rangeley processor
because it is designed so that only the processor can write
the higher memory areas. This prevents USB and SATA from bus-mastering
into the buffers when they're set in the typical 0xE0000 area.
This will be set to Y unless defaulted to N by the mainboard or
chipset.

Install the BL1 and set up the checksum in the Makefile instead of relying on
post processing. Import the exynos checksum script, split it in two and
simplify it significantly. Stop putting the CBFS header in the midst of the
bootblock so that it can be checksummed before CBFS is put together. Stop
saving space for it and leaving an anchor in the bootblock which nobody looks
for.

This is needed for the tegra124's bootblock and includes enough implementation

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

coreboot to live at the end of RAM, or in SRAM

Provide functionality to create dynamic classes based on program name and
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class. Also, compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.
One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

This patch enhances the armv7 exception handlers in Coreboot and
libpayload to show the correct SP and LR registers from the aborted
context, and also dump a part of the current stack. Since we cannot
access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).

These functions add support for cooperative multitasking.
Currently, since we only have one ARM SOC that uses or supports multitasking,
arch_get_thread_stackbase returns CONFIG_STACK_BOTTOM for the thread stack.
We may end up having to make a cpu-specific function that arch_get_thread_stackbase calls,
but let's avoid adding complexity until we're sure we need to. We also wish to avoid
creating Yet Another Config Variable but will do so if pressed.
The switch code only saves r4-r11 and lr, which is consistent with the standard.

On x86, cpu_info lives at the top of stack. Make the arm do that as
well, as the threading model needs that and so will multicore support.
As part of this change, make the stack size a power of 2.
Also make it much smaller -- 2048 bytes is PLENTY for ram stage.
Note that the small stack size is counterintuitive for rom stage. How
can this work in rom stage, which needs a HUGE stack for lzma? The
main use of STACK_SIZE has always been in ram stage; since 2002 or so
it was to size per-core stacks (see, e.g.,
src/arch/x86/lib/c_start.S:.space CONFIG_MAX_CPUS*CONFIG_STACK_SIZE
and, more recently, thread stacks. So, we define the STACK_TOP for rom
and ram stage, but the STACK_SIZE has no real effect on the ROM stage
(no hardware red zones on the stack) and hence we're ok with actually
defining the "wrong" stack size. In fact, the coreboot_ram ldscript
for armv7 sizes the stack by subtracting CONFIG_STACK_BOTTOM from
CONFIG_STACK_TOP, so we replicate that arithmetic in bootblock.inc
Observed stack usage in ramstage:
BS: BS_PAYLOAD_LOAD times (us): entry 1 run 153887 exit 1
Jumping to boot code at 23104044
CPU0: stack: 02072800 - 02073000, lowest used address 020728d4, stack used: 1836 bytes
entry = 23104044
Which means we do need 2K, not 1K.

ARM: Fix cache cleaning operation.
There was no behavior defined for OP_DCCSW in dcache_op_set_way, so it
silently did nothing. Since we started using that to clean the cache between
stages and I have a change that enables caches earlier on, this was preventing
booting on pit.

Virtual Wire mode is set by writing 0 to the the MPTable
Feature2 bit field 'IMCR'. The virtualwire variable was
initially defined as writing a 1 to this bit field which
would actually set PIC mode instead of Virtual Wire mode.
However, nearly every mainboard called the MPTables with
virtualwire = 0, which actually had the effect of setting
Virtual Wire mode. I am correcting the definition but
leaving the call to write the MPTables with virtualwire = 0,
which is how most mainboards are already setting the tables
up.
See the MP Spec table 4-1 for more details:
Bit 7: IMCRP. When the IMCR presence bit is
set, the IMCR is present and PIC Mode is
implemented; otherwise, Virtual Wire Mode is
implemented.

Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.
