And move the pre-hardwaremain post code to 0x79
so it comes before hardwaremain at 0x80.

Emit these codes from ACPI OS resume vector as well
as the finalize step in bd82x6x southbridge.

Vadim Bendebury 6d18fd09c3 Utility to dump boot timing table
Coreboot and u-boot create a table of timestamps which allows to see
the boot process performance. The util/cbmem/cbmem.py script allows to
access the table after ChromeOS boots up and display its contents on
the console. The problem is that shipping images do not include Python
interpreter, so there is no way to access the table on a production
machine.

This change introduces a utility which is a Linux app displaying the
timestamp table. Conceivably the output of this utility might be
included in one of the ChromeOS :/system sections, so it was attempted
to write this procedure 'fail safe', namely reporting errors and not
continuing processing if something goes wrong.

Including of coreboot/src .h files will allow to keep the firmware
timestamp implementation and this utility in sync in the future.

Test:
    . build the utility (run 'make' while in chroot in  util/cbmem)
    . copy `cbmem' and 'cbmem.py' to the target
    . run both utilities (limiting cbmem.py output to 25 lines or so)
    . observe that the generated tables are identical (modulo rounding
      up of int division, resulting in 1 ns discrepancies in some
      cases)

If these values are non-zero then the kernel will issue
an SMI for each core (cstate) and package (pstate).

Since we don't do anything with these SMI callbacks we
can avoid taking the extra SMIs at boot time by zeroing
these fields.

Vadim Bendebury d0b860aada Add utility for parsing/modifying DTD array
Detailed timing descriptor (DTD) is an 18 byte array describing video
mode (screen resolution, display properties, etc.) in Intel Option
ROM. Option ROM can support multiple video modes, specific mode is
picked by the BIOS through the appropriate Option ROM callback
function.

The new utility allows to interpret the 18 byte hex DTD dump, and/or
modify certain values, and generate a new DTD.

To parse the DTD contents just pass the 18 bytes to the utility in the
command line. To modify the existing contents and generate a new dump
precede the 18 bytes with '-m' and follow prompts.

The endianness of an architecture is now set up automatically using Kconfig
and some common code. The available conversion functions were also expanded
to go to or from a particular endianness. Those use the abbreviation le or be
for little or big endian.

Built for Stumpy and saw coreinfo cbfs support work which uses network
byte order. Used the functions which convert to little endian to implement an
AHCI driver. The source arch is also little endian, so they were effectively
(and successfully) inert.

Duncan Laurie 4b1610d766 RTC: Don't clear pending interrupt in resume path
The linux kernel relies on the RTC reporting pending interrupts if
the RTC alarm was used to wake the system.  If we clear these flags
here then the rtc-cmos driver in the kernel will think that no
interrupts are pending and will not re-start the timerqueue to
handle the alarm timerqueue node.

This flag doesn't exist in SMM but the rtc code is compiled there.
Since rtc_init() is not called by SMM it is guarded with an ifdef.

I performed several thousand suspend/resume cycles without seeing
an issue where hwclock was unable to read from /dev/rtc.  There
still is a potential kernel issue where the timerqueue can stall
but this makes that much less likely to happen on resume.

Tested by adding events to the event log at runtime on a

Vadim Bendebury f27d36c361 Fix cbmem to work on 64 bit platforms
For some reason which I fail to understand, specifying endiannes using
'@' (which means 'native' and should be the same as '<' on x86
platforms) causes cbmem.py to crash the machine on 64 bit systems.

What happens is that the addresses read from various table headers'
struct representations do not make sense, when bogus address gets
passed to get_phys_mem, the crash happens while that function is
executed.

dlaurie@ found out that replacing "@" with "<" in fact fixes the
issue. After some investigation I am just submitting this fix without
much understanding of the root cause.

Stefan Reinauer a90bd527d9 cbfstool: add offset parameter to create command
CBFS allows coreboot rom images that are only partially covered
by the filesystem itself. The intention of this feature was to
allow EC / ME / IMC firmware to be inserted easily at the beginning
of the image. However, this was never implemented in cbfstool.

This patch implements an additional parameter for cbfstool.

If you call cbfstool like this:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
it will now create an 8M image with CBFS covering the last 1M of
that image.

Test:
     cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
     creates an 8M image that is 7M of 0xff and 1M of CBFS.
