2013-10-22usbdebug: Fix boards without EARLY_CBMEM_INITKyösti Mälkki
The main usbdebug file lib/usbdebug.c was removed from romstage build with commit f8bf5a10 but the chipset-specific parts were not, leading to unresolved symbol errors for AMD platforms. Add a silent Kconfig variable USBDEBUG_IN_ROMSTAGE for convenient use of this feature.

2013-08-29usbdebug: Support choice of EHCI controllerKyösti Mälkki
Nowadays, chipsets or boards do not only have one USB port with the capabilities of a debug port but several ones. Some of these ports are easier accessible than others, so making them configurable is also necessary. This change adds infrastructure to switch between EHCI controllers, but does not implement it for any chipset.

2013-08-29usbdebug: Change debug port scanningKyösti Mälkki
On AMD platforms, setting of USBDEBUG_DEFAULT_PORT=0 tries to scan all physical ports one after other in incrementing order. To avoid possible problems with other USB devices, one can select the port number here and bypass the scan. Intel platforms can communicate with usbdebug dongle on one physical port only, and this option makes no difference there.

The tests for __PRE_RAM__ or __SMM__ were repeatedly used for detection if dev->ops in the devicetree are not available and simple device model functions need be used. If a source file build for ramstage had __PRE_RAM__ inserted at the beginning, the struct device would no longer match the allocation the object had taken. This problem is fixed by replacing such cases with explicit __SIMPLE_DEVICE__.

2013-07-01usbdebug: Drop duplicates of EHCI BAR relocation codeKyösti Mälkki
All the additional work that needs to be done in EHCI BAR relocation is independent of the hardware platform and was functionally identical in all the copies removed. When USBDEBUG is not selected, PCI EHCI controllers use standard pci_dev_read_resources() call. With USBDEBUG selected, PCI EHCI controller's device_operations .read_resources is replaced with pci_ehci_read_resources() call, which in turn will replace the device_operations .set_resources call. The replacement for .set_resources reconfigures usbdebug driver side, and calls the original .set_resources to configure hardware side.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

As we move to supporting other systems we need to get rid of assembly where we can.

2011-02-12Attached patch fixes the LPC decode ranges of SB600/SB800. We enable early ↵Rudolf Marek
only Serial/SIO/RTC. Everything else needs to be done by lpc.c Problem was that early settings survived, because the lpc.c is doing ORs only... Hence we decode quite a lot and even strange ranges like IO port 0x4600 etc... Also, if some port which does not fit to predefined set is requested, like 0x290 for Hardware monitor, the wide port is done, but in our case it has range 512 bytes which means we decode in fact 0x290 - 0x490. And if we hit GPU in the 0x3bx range I receive MCE exception if I do isadump -f 0x300 which is bad. Therefore If I detect that the requested range is small (16 bytes) I additionally set the small wide io region so only 16 bytes is decoded. While at it, I fix spelling typos and I init the regs so we don't write random garbage to regs even if we don't enable them later.
