OK, this is tl;dr. But I need to write this in hopes we make
sure we don't put code like this into coreboot. Ever.
Our excuse in this case is that it was imported, not obviously wrong,
and easily changed. It made sense to get it in, make it work, then
do a cleanup pass, because changing everything up front is almost
impossible to debug.
The exynos code has bunch of base register values, e.g.
These are base addresses of things that look like a memory-mapped
struct. To get these to a pointer, they created the following macro,
which creates an inline function.
static inline unsigned int samsung_get_base_##device(void) \
{ \
return cpu_is_exynos5() ? EXYNOS5_##base : 0; \
}
And then invoke it 31 times in a .h file, e.g.:
SAMSUNG_BASE(clock, CLOCK_BASE)
to create 31 functions.
And then use it:
struct exynos5_clock *clk =
(struct exynos5_clock *)samsung_get_base_clock();
OK, what's wrong with this? It's easier to ask what's right with it. Answer: nothing.
I have a long list of what's wrong, and I may leave some things out,
but here goes:
1. the "function" can return a NULL if we're not on exynos5. Most uses of the code
don't check the return value.
2. And why would this function be running, if we're not on an exynos5? Why compile it in?
3. Note the cast everywhere a samsung_get_base_xxx is used.
The function returns an untyped variable, requiring the *user* to get two
things right: the cast, and the function invocation. One can replace that _clock(); with
_power(); in the code above, and they will be referencing the wrong registers, and
they'll never get an error!
We have a C compiler; use it to type data.
4. You're generating 31 functions using cpp each and every time the file is included.
The C compiler has to parse these each time. It's not at all like a simple cpp
macro which is only generated on use.
5. You can't tags or etags this code
6. In fact, any kind of analysis tool will be unable to do anything with this cpp magic.
That's only a partial list.
So what's the right way to do it? Just make typed constants, viz:
Or, since I expect people will want the lower case function syntax, I've left
it that way:
Now we've got something that is efficient, and we don't even need to protect with
any more.
Hence this change. We've got something that is type checked, does not require users to
cast on each use, will catch simple programming errors, can be analyzed with standard tools,
and builds faster.
So if we make a mistake:
struct exynos5_clock *clk =
samsung_get_base_adc();
We'll see it:
src/cpu/samsung/exynos5250/clock.c: In function 'get_pll_clk':
src/cpu/samsung/exynos5250/clock.c:183:3: error: initialization from incompatible pointer type [-Werror]
which we would not have seen before.
As a minor benefit, it shaves most of a second off the compilation.

If you try to reset the system with outb(3,0x92), outb(4,0xcf9) or a
triple-fault it will instead crash with a messy screen. As the more common
outb(0xFE, 0x64) doesn't work with our setup, Linux will crash whenever you
ask it to reboot. Closer inspection shows that on a warm boot of Coreboot
agesawrapper_amdinitpost() always fails with error code 7. Looks like DDR3
re-init goes wrong somehow. I tried find the reason for this but was
unable to. I am convinced this is not board specific but a bug in AGESA.
In the end I had to settle for a workaround: if amdinitpost returns 7 this
patch resets the system harder with outb(0x06, 0x0cf9), after that RAM init
will succeed. As amdinitpost is early in POST this automatic reset is
quick enough not to be noticable.
I'd perfer a real fix, but that's all I have.

Step 2: change the Persimmon code to adapt it to the new board's hardware.
The Toucan-AF is a COM Express Compact Type 6 form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
- 1-4 GB DDR3 memory down
- 1x VGA, 2x DisplayPort (1 switchable to LVDS)
- AMD A55E (Hudson-E1) southbridge
- 8x USB 2.0
- 4x SATA
- HD Audio (with codec on baseboard)
- NEC uPD78F0532 microcontroller on I2C ("SEMA")
- 7x PCIe2.0 x1 (1 on PEG)
- Intel I210 GbE (on APU PCIe x1, can be disabled for additional PCIe)
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)
The Toucan-AF has no SIO on board. This patch includes basic support for a
Winbond W83627DHG (PS/2, 2x RS232), because the ADLINK ExpressBase-6 used
for evaluation happens to have one. The code may have to be adapted to the
actual baseboard of the application.

Currently on for example on AMD Persimmon and ASRock E350M1 Linux
complains, that the PBLK length is invalid [1].
ACPI: Invalid PBLK length [0]
Consequently, frequency scaling might not work correctly, though for
these two boards it seems to work according to PowerTOP.
Indeed, according to the ACPI specification [2], setting PBlockLength
to 0 is only allowed if there is no PBlockAddress. Otherwise it has to
be set to 6.
18.5.93 Processor (Declare Processor)
[…]
PBlockAddress provides the system I/O address for the processors
register block. Each processor can supply a different such
address. PBlockLength is the length of the processor register
block, in bytes and is either 0 (for no P_BLK) or 6. With one
exception, all processors are required to have the same
PBlockLength. The exception is that the boot processor can have
a non-zero PBlockLength when all other processors have a zero
PBlockLength. It is valid for every processor to have a
PBlockLength of 0.
And that is exactly what Linux is checking in
`drivers/acpi/processor_driver.c` [3].
static int acpi_processor_get_info(struct acpi_device *device)
{
[…]
/*
* On some boxes several processors use the same processor bus id.

* CPU+CPU ID.
*/
sprintf(acpi_device_bid(device), "CPU%X", pr->id);

pr->acpi_id));

request_region(pr->throttling.address, 6, "ACPI CPU throttle");
}
[…]
}
This issue has proliferated to all AMD based boards so fix it for
all of them by setting P_BLK length to 6.
The DSDT of for example AMD Parmer and AMD Thatcher also set it
to 6 everywhere so this solution is taken instead of setting the
P_BLK system I/O base to 0 for all but the first processor which
is how it is done for earlier AMD based boards.
As note having to set this manually should not be needed and
this should be autogenerated as done for most of the Intel boards
and the AMD K8 based boards (`src/cpu/amd/model_fxx/powernow_acpi.c`).

The DSDT header contains the fields OEMID and OEM Table ID. See
for example ACPI specification 4.0a [1]
5.2.11.1 Differentiated System Description Table (DSDT)
on page 135. There Table 5-16 contains the descriptions.
Field Byte Length Byte Offset Description
===================================================
OEMID 6 10 OEM ID
OEM Table ID 8 16 The manufacture model ID.
Currently in coreboot there is no common method what to put in
these fields.
Mostly Intel based boards populate it with "CORE " ore "COREv4"
and AMD based boards populate it with the board vendor and
model number, abbreviated appropriately to fit into these fields.
On most boards the proprietary vendor BIOS seems to leave these
fields – displayed with `sudo dmidecode` under System Information –
blank
To Be Filled By O.E.M.
and fill out the Base Board Information with the board vendor and
model name.
In [2] Jens Rottmann argues that the this is really just the table
ID used for naming it and that »99% of the DSDT code is not board
specific«.
Both approaches seem to have their advantages, but using the
second one, developers often seem to forget to update them (for
example AMD Thather).
The current situation is at least not optimal. and therefore at
least unify the string in the OEM Table ID. If unifying the
OEM ID is also a good idea this should be done too.
If later on it should be decided that the board vendor and model
should be used again, this should be somehow derived from
Kconfig.
The following command was used for the change [3].
$ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/'
This patch is split out from [2].

These were not separable or it would have been two CLs.
Enable CHROMEOS configure option on snow. Write gpio support code for
the mainboard. Right now the GPIO just returns hard-wired values for
"virtual" GPIOs.
Add a chromeos.c file for snow, needed to build.
This is tested and creates gpio table entries that our hardware can use.
Lots still missing but we can now start to fill in the blanks, since
we have enabled CHROMEOS for this board. We are getting further into
the process of actually booting a real kernel.

To reduce the differences between these file name the enabling

`mainboard_enable` [1].
Thanks to the awesome help of gnomon and BlastHardcheese in the
IRC channel #sed on <irc.freenode.net>. gnomon came up with the
following command to do the actual work.
$ cd src/mainboard
$ for f in */*/mainboard.c ; \

`src/mainboard/digitallogic/msm586seg/mainboard.c` and
`src/mainboard/technologic/ts5300/mainboard.c` had to be adapted
manually as no comma was used separating the struct members.
And with the following statement, gnomon is even more likable!
My pleasure entirely. Good luck with coreboot; I'm a big fan of the project.
