Dave Frodin ea90963666 AMD Hudson: Add support for the SD controller
This patch provides the correct SD controller timings for
the Family16 device. It also will remove the SD controller
from PCI space when device 0:14.7 is set to off in devicetree.
This was tested on a AMD Parmer board and a AMD G-series SOC
reference board. The settings were found in the AMD
Hudson2 RRG and family16 BKGD.

Nico Huber 9029265cf5 libpayload: Fill gaps in the xHCI driver
Well, it turned out to be more as some gaps ;)
but we finally have xHCI running. It's well tested against a QM77 Ivy
Bridge board.

We have no SuperSpeed support (yet). On Ivy Bridge, SuperSpeed is not
advertised and USB 3 devices will just work at HighSpeed.

There are still some bit fields in xhci_private.h, so this might need
little more work to run on ARM.

Nico Huber 0b78de2ee9 libpayload: Add a generic driver for usb hubs
The current drivers for external usb hubs and root hubs all follow
the same pattern. Before adding another one with 90% of the same code,
extract the common parts and rewrite them with a simple interface.

This also adds debouncing of new attachments. Current drivers just
waited 100ms before they reset the device. However, we should check
if the device becomes disconnected and reconnected during this period.

Porting of the current hub drivers will take place in separate
commits (when I have time to test the older HCIs).

Nico Huber aee44fa37d libpayload: usb: Add interval attribute to endpoints
Read bInterval from endpoint descriptors and store it in our endpoint_t
struct. The interval is encoded dependently on the device' speed and the
endpoint's type. Therefore, it will be normalized to the binary logarithm
of the number of microframes, i.e.
  t = 125us * 2^interval

The interval attribute will be used in the xHCI driver.

Patrick Georgi 482af6d15c libpayload: Redirect USB slave init through controller driver
xHCI requires special treatment of set_address since it determines
the device number itself (instead of the driver, as with the other
controllers). The controller also wants to validate a chosen device
configuration and we need to setup additional structures for the
device and the endpoints.

Therefore, we add three functions to the hci_t structure, namely:
  set_address()
  finish_device_config()
  destroy_device()
Current implementation for the Set Address request moved into
generic_set_address() which is set_address() for the UHCI, OCHI and
EHCI drivers. The latter two are only provided as hooks for the xHCI
driver.

The Set Configuration request is moved after endpoint enumeration.
For all other controller drivers nothing changes, as there is no other
device communication between the lines where the set_configuration()
call moved.

Siyuan Wang d2ae6ae789 AMD Thatcher: fix issue 'S3 fails to suspend after wake up from USB keyboard'
This issue can be reproduced in Linux by the following steps:
1) use pm-suspend to suspend.
2) use USB keyboard to wake up.
3) use pm-suspend to suspend. FAIL To SUSPEND.

The cause of this issue is:
USB devices use bit 11(0x0b) of GP0_STS represents S3 wake up event,
but this bit is not clear after wake up. So OS thinks there is a
wake up signal and wake up immediately.

In this patch, I add AcpiGpe0Blk using MMIO access and write 1
on bit 11. Write 1 to clear as spec says.
I have tested on Thatcher

The same change was done for AMD Parmer in commit »AMD Parmer:
fix issue 'S3 fails to suspend after wake up from USB keyboard'
(03901124) [1].

Gabe Black 1ef5ff2770 am335x: Make the iROM load only the bootblock and ROM stage.
The bootblock and ROM stages are the only ones that are really required to be
loaded in the quite limited on chip RAM during startup. Rather than load the
whole image which requires everything to be small, load just the bootblock and
the ROM stage, allowing the rest of the image to be arbitrarily large. Loading
a minimal amount of stuff should also improve boot performance a little bit.

Gabe Black 437a1e67a3 beaglebone: Expand "ROM" size to 4MB.
Now that the ROM size is decoupled from the size of the on chip RAM,
it's size is now only constrained by the size of the medium it's loaded
from and the memory it's being loaded into, probably GBs in both cases.
Making it 4MB is a reasonable compromise between giving the payload lots
of breathing room and wasting space on the source medium which won't be
used.

The VX900 can be connected to either DDR2 or DDR3. On my board, it is

This is the raminit for DDR3 dimms for the VX900. I like the term

What works and what doesn't is documented in the code. It does not

Alexandru Gagniuc 5239ba2f8f ramtest.c: Add silent ram_check
In some cases, we want a ram_check that does not die and does not
clobber the terminal with useless output that slows us down a lot.
Usage examples include Checking if the RAM is up at the start of
raminit, or checking if each rank is accessible as it is being
initialized.

As with all other ram_checks, this is more of a "Is my DRAM properly
configured?" test, which is exactly what we want for something to use
during memory initialization.

Gabe Black ddbfc645c2 am335x: Build an omap style header and an image with it at the front.
Loading on an OMAP SOC requires that the first sector of the image have a
configuration header, and, when not an execute in place image, an additional
header which describes how big the image is and where it should be loaded.
This change adds some infrastructure to statically build that header using C
code, and to paste the header onto the front of coreboot.rom in a new top
level target file called MLO.

The configuration header we're using is as inert as possible, in line with
what U-Boot is doing. I think it could be used to give additional
configuration parameters to the built-in ROM on the SOC, but we don't need to
do that, and there didn't seem to be any actual documentation how to do that.
Because the header is built from C and is defined per CPU, it would be
possible to include extra settings in other CPUs if desired.

Adding a new top level build target is a bit disruptive, but should be
contained to the am335x directory and not interfere with other mainboards.

Gabe Black b7d81e05bb ARM: Put the ROM stage into the image before other bits.
On ARM, there's frequently some firmware built into the SOC which runs
first and which loads other firmware like Coreboot from some other
media. To prevent the bootblock from having to know how to find and load
the ROM stage from what may be a complicated source (sd card,
netbooting, etc.), we can put the ROM stage immediately after the
bootblock and ensure that they're both loaded at the same time.

This change adjusts the Makefile.inc for ARM so that the ROM stage is put
into the image before any other files so that we know it comes first.
This changes the behavior of the CONFIG_UPDATE_IMAGE config option used
by abuild, although it's not entirely clear whether that's still used.

Gerd Hoffmann 8130b1ec1b qemu: copy dsdt tables from SeaBIOS, adapt for coreboot and enable acpi
First copy over from SeaBIOS git repo, then adapt for coreboot:

Disable cpu/pci hotplug bits.  Disable dynamic pci window.
Both depend on stuff in the SSDT tables created by SeaBIOS.

Bits are left in, but deactivated via #if 0, so it's easier
to see the differences when diffing the coreboot tables with
the SeaBIOS tables.

Adapt dsdt DefinitionBlock.

Enable acpi table generation in acpi_tables.c.

With this patch linux boots successfully with ACPI enabled.
It's not bug-free though.  Missing cpu detection leads to
funky messages like this one:

  weird, boot CPU (#0) not listed by the BIOS.

and SMP most likely wouldn't work either.
