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 ?

2017-06-08device/Kconfig: Put gfx init methods into a `choice`Nico Huber
Provide all gfx init methods as a Kconfig `choice`. This elimates the option to select native gfx init along with running a Video BIOS. It's been only theoretically useful in one corner case: Hybrid graphics where only one controller is supported by native gfx init. Though I suppose in that case it's fair to assume that one would use SeaBIOS to run the VBIOS. For the case that we want the payload to initialize graphics or no pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the choice. If multiple options are available, the default is chosen as follows: * NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS, * VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS, * NATIVE_VGA_INIT, if we don't add a Video BIOS. As a side effect, libgfxinit is now an independent choice.

2017-04-27x86/acpi: Use initialized VBIOS in VFCT tableMarshall Dawson
AMD VBIOS option ROMs often modify themselves during initialization. Check for the presence of a VBIOS at 0xc0000 before populating the VFCT table. If a matching ROM is found, use it for the source of the copy. Tested on Gardenia (Stoney) variant by observing amdgpu driver's dmesg output.

2017-04-25lib: provide clearer devicetree semanticsAaron Durbin
The devicetree data structures have been available in more than just ramstage and romstage. In order to provide clearer and consistent semantics two new macros are provided: 1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE 2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST The ROMSTAGE_CONST attribute is used in the source code to mark the devicetree data structures as const in early stages even though it's not just romstage. Therefore, rename the attribute to DEVTREE_CONST as that's the actual usage. The only place where the usage was not devicetree related is console_loglevel, but the same name was used for consistency. Any stage that is not ramstage has the const C attribute applied when DEVTREE_CONST is used.

2016-12-27device/dram/ddr3: add FTB timingsNicola Corna
SPD revision 1.1 introduced FTB timings, an extra set of SPD values that specify a more precise tCKmin, tAAmin, tRCDmin, tRPmin and tRCmin. For backwards compatibility, the MTB is usually rounded up and the FTB part is negative. For this reason some memories were not set up optimally, as the FTB part was ignored and the resulting timing wasn't set to the minimum value. The tests were performed on a Lenovo X220 with two Micron 8KTF51264HZ-1G9E (1866 MHz): reading only the MTB part, coreboot reports a tCKmin of 1.125 ns, corresponding to a working frequency of 800 MHz; with the additional tCKmin FTB part (-0.054 ns) the new (rounded) value is 1.070 ns, valid for a 933 MHz operation. Tested also with Ballistix DDR3-1866 SODIMM on Lenovo T420: the memory is now detected as DDR3-1866 instead of DDR3-1600. Some manufacturers (like Micron) seems to expect a small rounding on the timings, so a nearest-value rounding is performed. If this assumption isn't correct, an error up to ~2 ps can be committed, which is low enough to be safely ignored.
