Christian Gmeiner 8b5b764af6 console: Make use of CONFIG_USE_OPTION_TABLE
It makes much more sense to use CONFIG_USE_OPTION_TABLE instead
of CONFIG_HAVE_CMOS_DEFAULT. As we want to read the used
debug_level from our CMOS. This change makes it possible to
change log_debug via nvramtool and make use of the new
value after a reboot/poweroff.

CONFIG_HAVE_CMOS_DEFAULT does have an other meaning

Aaron Durbin c15551ab08 dynamic cbmem: fix memconsole and timestamps
There are assumptions that COLLECT_TIMESTAMPS and CONSOLE_CBMEM
rely on EARLY_CBMEM_INIT. This isn't true in the face of
DYNAMIC_CBMEM as it provides the same properties as EARLY_CBMEM_INIT.
Therefore, allow one to select COLLECT_TIMESTAMPS and CONSOLE_CBMEM
when DYNAMIC_CBMEM is selected.  Lastly, don't hard code the cbmem
implementation when COLLECT_TIMESTAMPS is selected.

Stefan Reinauer 43e4a80a92 Fix race condition building console code
On ARMv7 the console code can also be built into
the bootblock. Currently building the ARM targets
on a reasonably fast machine can fail, because
console.bootblock.o is attempted to build before
build.h is created. This patch adds a specific
rule for the bootblock variant of console.c, to
match the other variants so that the race condition
goes away.

Ronald G. Minnich 79e36d9060 Improve how our printk calls do_div by using constants.
The do_div code has a nice optimization in it when it is called with
constants. The current highly generalized use of it defeats those
optimizations and causes trouble on ARM, resulting in a complex and
buggy code path.

Since we only need to print in bases 8, 10, and 16, do a minor
restructuring of the code so that we call do_div with constants.
If you need base 2, print in base 16 and do it in your head. :-)

This fixes an ongoing problem with ARM, will not harm X86, and will
help PPC should we ever want to support it again.
Plus, I don't have to ever try to understand the div64 assembly and where
it's going wrong :-)

David Hendricks 6a503b6a0f make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.

This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.

The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.

uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

This enables POST codes by default using "default y" to avoid

Some mainboards have really nice capabilities for posting, beyond
simple POST cards. Further, some can not use a POST card. This
change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.

If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:

void mainboard_post(u8 value)
{
	switch(value){
		case POST_TIME_TO_PARTY: some_fancy_lights();
		break;
	}
}

Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

BUG=None

TEST=Build and boot a google chromebook. Observe that it still works. Use it to drive
some pretty lights.

Vadim Bendebury 32da8bed19 CBMEM CONSOLE: Add CBMEM console driver implementation.
The CBMEM console driver saves console output in a CBMEM area, which
then is made available to Linux applications for perusing.

There are some system limitations which need to be worked around
to achieve this goal:

- some console traffic is generated before DRAM is initialized,
  leave alone CBMEM initialized.

- after the RAM based stage starts, a lot of traffic is generated
  before CBMEM is initialized.

As a result, the console log lives in three different places -
the bottom of the cache as RAM space, the CBMEM buffer (where it
is expected to be) and a static buffer used early in the RAM
stage.

When execution starts (in the cache as RAM mode), the console
buffer is allocated at the bottom of the cache as RAM memory
address range. Once DRAM is initialized, the CBMEM structure is
initialized, and then the console buffer contents are copied from
the bottom of the cache as RAM space into the CBMEM area right
before the cache as RAM mode is disabled. The
src/lib/cbmem_console.c:cbmemc_reinit() takes care of the
copying.

At this point the cache as RAM memory is about to be disabled,
but the ROM stage is still going generating console output. To
make sure this output is not lost, cbmemc_reinit() saves the new
buffer address at a fixed location (0x600 was chosen for this),
and the actual "printing" function checks to see if the RAM is
already initialized (the stack is in RAM), and if so, gets the
console buffer pointer from this location instead of using the
cache as RAM address.

When the RAM stage starts, a static buffer is used to store the
console output, as the CBMEM buffer location is not known. Then,
when CBMEM is reinitialized, cbmemc_reinit() again takes care of
the copying.

In case the allocated buffers are not large enough, the excessive
data is dropped, and the copying routine adds some text to the
output buffer to indicate that there has been data lost and how
many characters were dropped.

Vadim Bendebury c34b463128 CBMEM CONSOLE: Add config option for CBMEM stored console log.
Some experiments have demonstrated that total amount of text
generated by coreboot console when BIOS_SPEW level is enabled
exceeds 40KB.

Console output generated before DRAM is initialized can exceed
2KB. This patch introduces the new configuration option and
assigns adequate default values to cache based and DRAM based
console buffers.

BUG=chrome-os-partner:4200
TEST=manual

 . run the following commands in the root directory

   cp config.stumpy .config
   make menuconfig

 . enable the new option (Console->Send console output to a CBMEM buffer)
 . save the configuration

+CONFIG_CONSOLE_CBMEM=y
+CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0xae00
+CONFIG_CONSOLE_CAR_BUFFER_SIZE=0xc00

Sven Schnelle 20fc631ad2 Fix usb debug dongle support
- move enable_usbdebug() declaration to usbdebug.h
- reinitialize debug driver in ramstage, as copying the data
  structure from romstage doesn't work right now. This way of copying
  data from romstage to ramstage is really board/cpu specific, and is
  likely to break often. So don't do it.

Kevin O'Connor a68555f48d Do full flush on uart8250 only at end of printk.
The previous code does a full flush of the uart after every character.
Unfortunately, this can cause transmission delays on some serial
ports.

This patch changes the code so that it does a flush at the end of
every printk instead of at the end of every character.  This reduces
the time it takes to transmit serial messages (up to 9% on my Asrock
e350m1 board).  It also makes the transmission time more consistent
which is important when performing timing tests via serial
transmissions.
