Aaron Durbin 3948e5392b program loading: introduce struct prog
The struct prog serves as way to consolidate program
loading. This abstraction can be used to perform more
complicated execution paths such as running a program
on a separate CPU after it has been loaded. Currently
t124 and t132 need to do that in the boot path. Follow
on patches will allow the platform to decide how to
execute a particular program.

Note: the vboot path is largely untouched because it's
already broken in the coreboot.org tree. After getting
all the necessary patches pushed then vboot will be
fixed.

Julius Werner c3e7c4e7b4 Clean up architecture-specific Kconfigs
It's an unfortunate side effect of our different-archs-per-stage
mechanism that all src/arch/*/Kconfig files are always parsed with no
if blocks to exclude them if they're not relevant. This makes it very
easy to accidentally rely on a Kconfig default set by a totally
different and not applying architecture.

This patch moves a few Kconfigs from ARM and X86 that leaked out like
this into a common Kconfig file for clarity. It also gives ARM64 its
own BOOTBLOCK_CUSTOM mechanism so that it doesn't leech off the ARM one
(currently not used by any board).

In the future, we should maybe prefix all options in the arch/*/Kconfig
files with the architecture name (such as X86_BOOTBLOCK_NORMAL and
ARM_LPAE are already doing), to make it more apparent when they are used
in the wrong place.

BUG=None
TEST=None (tested together with dependent changes)

It also creates file names in the build directory and with

Also some handling for non-.c/.S files was adapted to match.

This is inspired by the commit listed below, but rewritten to match

Vadim Bendebury b92e54333f mips: do not place branch instructions in branch delay slot
A branch instruction in a branch delay slot confuses the execution
pipeline and causes an exception.

bootblock.S was written 'by hand', has a branch instruction in branch
delay slot and includes '.set noreorder' directive, which causes it to
crash when trying to branch to main().

Adding a nop instruction fixes the problem. Also adding a nop after
the last branch in the file just in case main() returns and the object
linked next starts with a branch.

BUG=chrome-os-partner:31438
TEST=Running on the simulator can reach main() now

Julius Werner 635ee51b0d arm: Prevent compilation of old, experimental SMP support
The ARM SMP feature was added a long time ago and has never really been
used by anyone since. We are still always compiling cpu_info() even
though we don't use it, and it makes some dangerous assumptions about
stack alignment that are not guaranteed anywhere.

I'm planning to change the way the stack boundaries are defined. Rather
than trying to work that into this unsafe, unused and hard to test
feature, I think we should just seal it off with police tape and make
sure that if anyone ever tries to use it again (which currently seems
unlikely), they get forced to do their due diligence on making sure it
works as intended.

BUG=None
TEST=Compiled Veyron_Pinky.

of stuff that is necessary on x86 but nowhere else.
That cruft is now gone.

It also adopts the non-x86 approach of handling linker scripts,

concatenation (of just one file plus options).

2) Provides routines for exception entry and exception exit that can be used by
any program to implement exception handling. The only routine required by the
program would be exc_dispatch which handles the exception in its own required
way and returns by making a call to exc_exit. On exc_exit, the transition
library unwinds the whole stack by popping out the saved state of xregs

Aaron Durbin a5c7f66810 arm64: include stack storage within ramstage
Instead of defining the stacks by Kconfig options include
the stack sizes for all the CPUs including each of their
exception stacks. This allows for providing each CPU
on startup a stack to work with.

Note: this currently inherits CONFIG_STACK_SIZE from x86 because
of the Kconfig mess of options not being guarded.

With CONFIG_RETURN_FROM_VERSTAGE false, the verstage loads the romstage over
the bootblock, then exits to the romstage. this is necessary for some SOC
(e.g. tegra124) which runs the bootblock on a different architecture.

With CONFIG_RETURN_FROM_VERSTAGE true, the verstage returns to the bootblock.
Then, the bootblock loads the romstage over the verstage and exits to the
romstage. this is probably necessary for some SOC (e.g. rockchip) which does not
have SRAM big enough to fit the verstage and the romstage at the same time.

Aaron Durbin 9ef9d85976 bootstate: use structure pointers for scheduling callbacks
The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.

In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

Currently, the rmodules inclusion for vboot is dependent on ramstage_arch.
This change adds dependency on romstage_arch, since vboot is associated with
romstage. Inclusion based on ramstage_arch is left as is in case someone needs
it in ramstage.

Furquan Shaikh fbff908a74 coreboot classes: Add dynamic classes to coreboot
Provide functionality to create dynamic classes based on program name and the
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 and 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.

Ramstage needs an assembly entry point for setting up
the initial state of the CPU. Therefore, a function is
provided, arm64_el3_startup(), that bootstraps the state
of the processor, initializes the stack pointer, and
branches to a defined entry symbol. To make this work
without adding too much preprocessor macro conditions
provide _stack and _estack for all the stages.

Currently the entry point after initialization is 'main',
however it can be changed/extended to do more work such
as seeding the stack contents with tombstones, etc.

It should be noted that romstage and bootblock weren't
tested. Only ramstage is known to work.

Stefan Reinauer 77b1655d9b vboot2: add verstage
This reverts the revert commit 5780d6f387
and fixes the build issue that cuased it to be reverted.

Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.

Daisuke Nojiri 320647abda vboot2: add verstage
Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains, compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with verstage_.

TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

Stefan Reinauer d6865222c8 misc: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.

Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)

This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.

Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.

Julius Werner 989e12bb63 arm: Fix stored PC value when handling exceptions
ARM processors save the PC value in the Link Register when they handle
and exception, but they store it with an added offset (depending on the
exception type). In order to make crashes easier to read and correctly
support more complicated handlers in libpayload, this patch adjusts the
saved PC value on exception entry to correct for that offset.

(Note: The value that we now store is what ARM calls the "preferred
return address". For most exceptions this is the faulting instruction,
but for software interrupts (SWI) it is the instruction after that. This
is the way most programs like GDB expect the stored PC address to work,
so let's leave it at that.)

section B1.8.3.

Vadim Bendebury 0b341b341d ipq/arm: Redesign hooks for bootblock
The following patches had to be squashed
to properly build all the different ARM boards.

ipq8064: storm: re-arrange bootblock initialization

The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.

As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.

Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

  . nyan_big, peach_pit, and storm targets build fine now.

arm: Redesign mainboard and SoC hooks for bootblock

This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.

Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.

Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

BRANCH=None
BUG=chrome-os-partner:32123
TEST=Booted on Pinky. Compiled for Storm and confirmed in the
disassembly that bootblock_soc_init() is still compiled in and called
right before the (now no-op) bootblock_mainboard_init().
