2019-01-07usbdebug: Initialize the HW once in CAR stagesArthur Heymans
The EHCI hardware needs to be initialized only once during CAR stages. Some exception need to be made when a blob messes with the EHCI hardware. To achieve this add a fixed location in the car.ld linker script such that the ehci debug information can be shared across CAR stages. Currently this means only romstage and bootblock, but verstage can also be hooked up later on. Tested on google/peppy: Both the bootblock and the romstage properly output console.

2018-12-04acpi_pld: Make it easier to define the ACPI USB device groupsDuncan Laurie
The Linux kernel can use the ACPI _PLD group information to determine peer ports. Currently to define the group information the devicetree must provide a complete _PLD structure. This change pulls the group information into a separate structure that can be defined in devicetree. This makes it easier to set for USB devices in devicetree that do not need a full custom PLD. This was tested on a sarien board with the USB devices defined by verifying that the USB 2/3 ports are correctly identified with their peer in sysfs.

2017-09-14usbdebug: Fix init and add support for postcarKyösti Mälkki
It was originally designed such that if usbdebug_init() was called before cbmem_initialize(), it would fetch the already-initialized state from CBMEM. This changed when cbmem_find() behaviour changed to require cbmem_initialize() to be called first. As a result, ramstage had to reinitialize all of the EHCI controller and USB endpoints on entry. This was slow, specially with AMD hardware where one can scan USB ports to probe for the debug dongle. For postcar and ramstage, move usbdebug entry such that it is triggered from CBMEM_INIT_HOOK instead of console_init(). Side-effect of this is usbdebug console shows 'coreboot-xxx ... starting...' line only for romstage. Initialisation for usbdebug is never done in postcar. If you have USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on usb either. While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE and alike.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages. BRANCH=None BUG=None TEST=Built and booted on Nyan_Blaze and Falco with and without CONFIG_CBMEM_CONSOLE.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed. BRANCH=None BUG=None TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once again show up. Compile-tested for Rambi and Samus.

2014-11-23usbdebug: Reduce bus reset delaysKyösti Mälkki
According to EHCI specification, host controller software stops the USB Reset condition by writing PORT_RESET=0. Software then poll-waits this bit until controller hardware has completed USB Reset sequence and read returns with PORT_RESET==0.

2014-11-23usbdebug: Fix migration to ramstageKyösti Mälkki
On entry to ramstage CBMEM is looked for a copy of an already initialized EHCI debug dongle state. If a copy is found, it contained the state before CAR migration and the USB protocol data toggle can be out of sync. It's an even/odd kind of a parity check, so roughly every other build would show the problem as invalid first line: 'ug found in CBMEM.' After CAR migration, re-direct the state changes to correct CBMEM table.
