2019-01-08amdfam10 boards: Fix regression on dev_find_slot() removalKyösti Mälkki
For these platforms, the first PCI node on devicetree is not the root of PCI bus hierarchy, and the topology (bus->children and dev->sibling links) are getting manipulated during HyperTransport enumeration. This workaround reverts back to old dev_find_slot() with its bad semantics.

2019-01-04device: Introduce pcidev_on_root() and friendsKyösti Mälkki
Semantics of dev_find_slot() are ill in the sense that it only works after device enumeration has completed in ramstage. Plan is to declare it as deprecated. Introduce pcidev_on_root() and pcidev_path_on_root() functions to replace cases where this was called with static argument bus == 0. New implementation only walks the root bus of the PCI tree, while old one walked the entire linked list of devices. Introduce pcidev_path_behind() to replace cases where argument bus != 0. The required parent node is typically one of the PCIe root functions that you locate using pcidev_on_root() above. New forms are safe to use with early devicetree and before PCI bus numbers have been assigned.

2018-12-30device/pci_early: Fixes for __SIMPLE_DEVICE__Kyösti Mälkki
The feature is used to enable PCI MMIO accesses behind PCIe links (or bridges) before PCI enumeration has been completed. Add the feature for bootblock, verstage and postcar, it is required with add-on PCIe serial cards for early console output. It's up to the board specific code to configure PCIe root port prior to calling console_init() for this to work. Remove feature from ramstage, it bypasses any resource allocations and bus number assignments. For the moment PCI configuration support before ramstage is available only on ARCH_X86. Also switch from device_t to pci_devfn_t.

2018-05-11devicetree: Add USB device typeDuncan Laurie
This commit adds support for describing USB ports in devicetree.cb. It allows a USB port location to be described in the tree with configuration information, and ACPI code to be generated that provides this information to the OS. A new scan_usb_bus() is added that will scan bridges for devices so a tree of ports and hubs can be created. The device address is computed with a 'port type' and a 'port id' which is flexible for SOC to handle depending on their specific USB setup and allows USB2 and USB3 ports to be described separately. For example a board may have devices on two ports, one with a USB2 device and one with a USB3 device, both of which are connected to an xHCI controller with a root hub: xHCI | RootHub | | USB2[0] USB3[2] device pci 14.0 on chip drivers/usb/acpi register "name" = ""Root Hub"" device usb 0.0 on chip drivers/usb/acpi register "name" = ""USB 2.0 Port 0"" device usb 2.0 on end end chip drivers/usb/acpi register "name" = ""USB 3.0 Port 2"" device usb 3.2 on end end end end end Change-Id: I64e6eba503cdab49be393465b535e139a8c90ef4 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/26169 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

Instead define the two fields (offset and mask) and use numbers.

A regression is hidden in commit 7eb0157fca33865783c1cc3c8e5cb2e327e551d7 (device/dram/ddr2.c: Decoding byte[12] bit7 as self refresh flag ), which breaks the build procedure when CONFIG_DEBUG_RAM_SETUP is set. Maybe it had better implement "printram" and the like as inline functions instead of macros.

2017-08-18Reinvent I2C opsNico Huber
Do not use the global platform_i2c_transfer() function that can only be implemented by a single driver. Instead, make a `struct device` aware transfer() function the only interface function for I2C controller dri- vers to implement. To not force the slave device drivers to be implemented either above generic I2C or specialized SMBus operations, we support SMBus control- lers in the slave device interface too. We start with four simple slave functions: i2c_readb(), i2c_writeb(), i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec- tive SMBus functions. But we keep aliases because it would be weird to force e.g. an I2C EEPROM driver to call smbus_read_byte().

2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`. Patched with Coccinelle using the clumsy spatch below and some manual changes: * Nested struct initializers and one field access skipped by Coccinelle. * Removed assumption in the code that I2C_M_RD is 1. * In `i2c.h`, changed all occurences of `chip` to `slave`. @@ @@ -struct i2c_seg +struct i2c_msg @@ identifier msg; expression e; @@ ( struct i2c_msg msg = { - .read = 0, + .flags = 0, }; | struct i2c_msg msg = { - .read = 1, + .flags = I2C_M_RD, }; | struct i2c_msg msg = { - .chip = e, + .slave = e, }; ) @@ struct i2c_msg msg; statement S1, S2; @@ ( -if (msg.read) +if (msg.flags & I2C_M_RD) S1 else S2 | -if (msg.read) +if (msg.flags & I2C_M_RD) S1 ) @@ struct i2c_msg *msg; statement S1, S2; @@ ( -if (msg->read) +if (msg->flags & I2C_M_RD) S1 else S2 | -if (msg->read) +if (msg->flags & I2C_M_RD) S1 ) @@ struct i2c_msg msg; expression e; @@ ( -msg.read = 0; +msg.flags = 0; | -msg.read = 1; +msg.flags = I2C_M_RD; | -msg.read = e; +msg.flags = e ?
