* smbus: Add a helper to generate SPD EEPROM dataBALATON Zoltan2019-02-041-0/+3
| | | | | | | | | | | There are several boards with SPD EEPROMs that are now using duplicated or slightly different hard coded data. Add a helper to generate SPD data for a memory module of given type and size that could be used by these boards (either as is or with further changes if needed) which should help cleaning this up and avoid further duplication.

* hw/i2c/smbus: Remove SMBusDevice from "qemu/typedefs.h"Philippe Mathieu-Daudé2019-01-221-0/+2
| | | | | | | | | | Files requiring SMBusDevice already include "hw/i2c/smbus.h". To clean "qemu/typedefs.h", move the forward declaration to "hw/i2c/smbus.h". Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
* i2c: pm_smbus: Fix the semantics of block I2C transfersCorey Minyard2018-08-231-2/+15
| | | | | | | | | | | | | | | | | The I2C block transfer commands was not implemented correctly, it read a length byte and such like it was an smbus transfer. So fix the smbus_read_block() and smbus_write_block() functions so they can properly handle I2C transfers, and normal SMBus transfers (for upcoming changes). Pass in a transfer size and a bool to know whether to use the size byte (like SMBus) or use the length given (like I2C). Signed-off-by: Corey Minyard <cminyard@mvista.com> Cc: Michael S.

* smbus: add a smbus_eeprom_init_one() routineCédric Le Goater2018-06-081-0/+1
| | | | | | | | | | | This is an helper routine to add a single EEPROM on an I2C bus. It can be directly used by smbus_eeprom_init() which adds a certain number of EEPROMs on mips and x86 machines.

* hw: move headers to include/Paolo Bonzini2013-04-081-0/+83
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
