260e85cd07 system: Copy the loader lastly before jumping.
The point at which we reloaded the loader was too early.  When items are
placed into .bss.slow via CONFIG_REPLACE_LOADER_WITH_BSS_SLOW, other
tasks could still access their variables that may have been in that
region after we had replaced those contents with the loader.  This
commit moves the reloading of the loader to as late as possible once all
tasks have done their HOOK_SYSJUMP work.

Also, fixed a bug with the .bss.slow section.  If a board is not using
the config option but items are placed in that section, that part of RAM
would not be cleared out.

9ed620f04b system: Add support to reclaim space from loader.
Certain ECs which cannot load both the RO and RW images into memory
simultaneously have a little firmware (LFW) loader that is loaded into
the beginning of the program memory.  This loader is responsible for
loading the RO/RW images, however once we begin executing code from
main(), the loader has already completed it's purpose.  We can reuse
this space by allocating portions of the .bss section here.  This
currently saves us 3k for mec1322.  This section is .bss.slow.

To use this feature simply define the following config option in
board.h.

  #define CONFIG_REPLACE_LOADER_WITH_BSS_SLOW

In some cases, such as the mec1322, this region of RAM is optimized for
code and not data.  Therefore, ideally infrequently used data should go
into this region.

094a81f5de cleanup: Handle signed RW images a bit cleaner
For signed EC RW images (CONFIG_RWSIG), there's no point in
embedding the public key or signature into the image itself since
it will just be replaced by the signer (either as the next step
in the build process, or after the fact for MP releases). This
takes that out and just points to where the pubkey and signature
will be placed.

I also checked the signatures with

  futility show -t build/*/ec.bin

They still look good, and the one signed image I booted (Cr50)

4ae115e145 Fix typo when building with CONFIG_SHAREDLIB
The board-specific board.h defines things like this:

  #define CONFIG_RO_SIZE 1000
  #define CONFIG_RW_SIZE 1000
  #define CONFIG_SHAREDLIB_SIZE 200

And in the linker scripts we define some preprocessor macros like
so:

  #define FW_SIZE_(section) CONFIG_##section##_SIZE
  #define FW_SIZE(section) FW_SIZE_(section)

So that we can say things like this:

    FLASH (rx) : ORIGIN = FW_OFF(SECTION), LENGTH = FW_SIZE(SECTION)

Note that we have to use FW_SIZE, not FW_SIZE_

The difference is only noticeable when SECTION is #defined. If
${CFLAGS} has

  -DSECTION=RW

Then the expansion is this:

  FW_SIZE_(SECTION)    =>   CONFIG_SECTION_SIZE
  FW_SIZE_(RW)         =>   1000

There's no difference in the output for this particular CL, but
we should use the correct macro anyway to avoid confusion.

6f8637a6df cortex-m: provide ability to insert free space into RO image base
Some platforms might expect the header of the image to be a certain
platform specific blob. This patch adds an ability to insert an
arbitrary size header in the binary blob, if so desired, the intention
is to have the platform specific tools to postprocess the image and

way too smart for this.

4626177c3b Atomic: Mark the modified uint32_t volatile
The atomic_* functions are often used in contexts where the data they
will operate on are volatile (due to being shared between tasks or a
task and an interrupt handler).  Adding volatile here makes using the
atomic_* functions a little easier in those cases and removes a cast
from the call sites (which could be obscuring a bug, if for instance
the variable was modified to be a uint16_t).

0e53f9d425 mec1322: heavysleep in idle task and console deepsleep
Implemented mec1322's heavysleep in idle task to
reduce further EC power down on S3.
MEC1322 needs sleep-enabled for all blocks to
acheive max power down including UART.
Real heavysleep will be effective only when
console/uart is not active.

To enable this commit, board-specific commit is required.
For example, check commit, "Enabling heavysleep idle task at S3".

Test:
1. Put device into S3 mode by typing 'powerd_dbus_suspend" in Linux
   shell.
2. wait at least 1 min till EC console sleeps
3. measure EC power.
   Since idle task is continuously scheduled, EC will enters/exits
   to/from heavy sleep mode frequently in S3 and power consumption
   will be changed dynamically.
   For acurate power measurement, high-sampling-rate measurement
   system might be required and using DMM might not give accurate
   number.

ce063e0829 build-infr: Add support for shared RO library.
This commit introduces the build infrastructure changes needed for
creating a shared RO library. (libsharedobjs).  The end goal is for the
library to contain various objects that can be shared with both the RO
and RW EC images.

Now, there are 3 make goals: ro, rw, and libsharedobjs.

In order for changes that are only specific to a single image (ie: RW
only) to be applied correctly, the object files are now built separately
for the RO, RW, shared objects library targets.

NOTE: Certain EC targets are incompatible with this model due to the
fact that only one image is present within flash at a time.

932eb3ddca flash: Add option to move pstate inside RO image
Currently, ECs with internal flash store the write protect state for
RO in a separate write/erase block of flash.  This is wasteful on
chips where there are not many blocks of flash.

Add a new CONFIG_FLASH_PSTATE_IN_BANK option which is defined by
default.  This is the old behavior, for compatibility.  (And we're
calling it 'bank' because that's what the existing code does, even if
the terminology is somewhat etymologically... bankrupt.)

If that config is #undef'd, then store the write protect flag directly
inside the RO image.  This uses only 4 bytes of the RO image, instead
of an entire erase block.  The magic numbers for the pstate values are
chosen such that when protecting RO, bits are only transitioned away
from their erased state.  Unprotecting RO once it's protected requires
reflashing RO; it's no longer possible to 'flashwp disable'.  But
that's ok, because realistically, the only reason to unprotect RO is
if you're about to flash the RO firmware anyway.

BUG=chromium:476659
BRANCH=none
TEST=Without undefining CONFIG_FLASH_PSTATE_IN_BANK, make sure everything
     still works on samus and samus_pd.  This ensures we didn't break the
     existing functionality:
         flashinfo -> no flags
         flashwp enable
         flashinfo -> ro_at_boot
         reboot
         flashinfo -> ro_at_boot
         flashwp disable
         flashinfo -> no flags
     Then recompile with #undef CONFIG_FLASH_PSTATE_IN_BANK and test:
         flashinfo -> no flags
         flashwp enable
         flashinfo -> ro_at_boot
         reboot
         flashinfo -> ro_at_boot
         flashwp disable -> fails with access denied
         flashinfo -> ro_at_boot
     Then reflash to verify that clears the ro_at_boot flag:
         flashinfo -> no flags

6ab1f5b703 usb: Remove unnecessary alignment for descriptors
This was causing the amount of data sent to be larger than the
total size of the descriptors.

Before this CL, connecting the Cr50 through USB gave this kernel
message:

  usb 2-1.4.7: config 1 descriptor has 1 excess byte, ignoring

When the host requests the descriptor, the code in chip/*/usb.c
that handles it looks like this:

	case USB_DT_CONFIGURATION: /* Setup : Get configuration desc */
		desc = __usb_desc;
		len = USB_DESC_SIZE;
                break;

But include/usb.h has this:

    #define USB_DESC_SIZE (__usb_desc_end - __usb_desc)

And both __usb_desc and __usb_desc_end come from the linker
script.

BUG=none
BRANCH=none
TEST=manual

Before this change, I built the Cr50 firmware from m/master,
tried it, and got the dmesg complaint on the host.

After this change, the dmesg complaint doesn't show up anymore.

3a1b5ec3dd cortex-m: disallow rescheduling if task_start() has not yet run
Most GPIO/peripheral interrupts are enabled in HOOK_INIT or some other
*_init() functions that are called before task_start(). Quite a lot of
these IRQ handler wake some task to process the interrupt, and this
causes a race condition. If the interrupt is triggered before
task_start() is called, the system may crash/hang/whatever.

Fix this by only allowing rescheduling tasks if task_start() is called.

74a98425ef USB: Fix issue with USB RAM sizes
Previously the USB RAM size was off by a factor of two
for chips that required 32-bit alignment of accesses,
even though the underlying memory was 16-bits in size.
This change adds an additional configuration for the
access size (it still assumes that the underlying memory
is 16-bits in size) and uses that to adjust the USB_RAM
memory section in the linker scripts.

This change also removes the default values for the USB
RAM from stm32/config_chip.h because they mask issues
when new chips are added.  It is better for a new chip
to fail to compile until these values are provided.

959dcf9854 stm32f: Add DMA interrupt handlers for channel 1 to 3
We already have interrupt handlers for channel 4 to 7. We need channel 3
for the new Ryu boards. Add the handlers for channel 1 to 3. Also,
instead of copy-pasting interrupt handlers, define a macro and declare
interrupt handlers with it.

BRANCH=None
BUG=chrome-os-partner:32660
TEST=make buildall
TEST=Check PD communication on the new Ryu board (with other CLs to
enable the new boards.)

beaddbf1a3 zinger: check RW firmware signature
The Zinger RW is now signed with 2048-bit RSA key (using SHA-256 as
digest).
This CL implements the verification mechanism.

note: the RSA key used for signing must be provided as a .pem file.
The path to .pem file must be provided in the PEM environment variable.
By default, it's using the dev key stored in zinger_dev_key.pem.

TEST=on Zinger, run with properly signed RW firmware and corrupted
firmware and check the serial traces.

cf62055270 Add options to disable rarely used console commands
'powerindebug' is only used when there is a problem with power
sequencing. 'taskready' is rarely used and the same info can be
retrieved by 'taskinfo'.

Put both behind config flags and disable 'taskready' by default. Also
disable 'powerindebug' for Ryu.

6473343075 better unhandled exception panic without runtime
On panic, reboot properly the CPU rather than just jumping to the reset
vector as that might lead to some incorrect initializations.

Properly plug the div by 0 to the panic handling.

Add a small trace if the debug output is activated.

TEST=add adhoc code triggering a data abort and see the firmware
printing a trace, then rebooting immediatly in a working state.
