2021-03-27x86: Make coreboot sysinfo available to any x86 boardSimon Glass
It is possible to boot U-Boot for chromebook_coral either 'bare metal' or from coreboot. In the latter case we want to provide access to the coreboot sysinfo tables. Move the definitions into a file available to any x86 board. Signed-off-by: Simon Glass <[email protected]>

2021-03-27x86: Probe device if needed in intel_gpio_xlate()Simon Glass
The Intel GPIO binding allows GPIOs to be globally numbered, so that it does not matter which GPIO bank is specified in the device tree. This is convenient and avoid confusion since the banks do not have the same number of GPIOs and the numbering is not sequential. The GPIO uclass ensures that the device mentioned in the devicetree binding is probed. It is fine for the driver to update gpio_desc to point to a different driver, but this may not have been probed. If it has not been, then it cannot be claimed since there is no uclass data. We could handle this in the GPIO uclass but so far it is an unusual situation so it is probably not worth the extra code. Handle this case in the GPIO driver by probing the selected device if necessary. Signed-off-by: Simon Glass <[email protected]>

2021-03-26dm: core: Use separate priv/plat data regionSimon Glass
Make use of the new priv/plat data region if enabled. This is implemented as a simple offset from the position set up by dtoc to the new position.

2021-03-26dm: core: Allow storing priv/plat data separatelySimon Glass
At present the device priv/data data allocated by dtoc is stored in the data section along with other variables. On some platforms it is better to allocate space for it separately, e.g. if SPL is running from read-only memory. Create a new space with the same size as that allocated by dtoc, ready for use.

2021-03-26dm: core: Move flags to device-runtime infoSimon Glass
When of-platdata-inst is active, use the flags in the new udevice_rt table, dropping them from the main struct udevice. This ensures that the latter is not updated at runtime. Signed-off-by: Simon Glass <[email protected]> Signed-off-by: Simon Glass <[email protected]>
2021-03-26dm: core: Create a struct for device runtime infoSimon Glass
At present when driver model needs to change a device it simply updates the struct udevice structure. But with of-platdata-inst most of the fields are not modified at runtime. In fact, typically only the flags need to change. For systems running SPL from read-only memory it is convenient to separate out the runtime information, so that the devices don't need to be copied before being used. Create a new udevice_rt table, similar to the existing driver_rt. For now it just holds the flags, although they are not used in this patch. Add a new Kconfig for the driver_rt data, since this is not needed when of-platdata-inst is used. Signed-off-by: Simon Glass <[email protected]> Signed-off-by: Simon Glass <[email protected]>

2021-03-26sandbox: i2c: Support i2c emulation with of-platdataSimon Glass
At present the i2c emulators require access to the devicetree, which is not possible (by design) with of-platdata. Add a way for drivers to record the of-platdata index of their emulator, so that we can still find the emulator. This allows i2c emulation to work with of-platdata.

2021-03-26dm: Rename device_get_by_driver_info_idx()Simon Glass
This function finds a device by its driver_info index. With of-platdata-inst we do not use driver_info, but instead instantiate udevice records at build-time. However the semantics of using the function are the same in each case: the caller provides an index and gets back a device. So rename the function to device_get_by_ofplat_idx(), so that it can be used for both situations. The caller does not really need to worry about the details.

2021-03-26dm: core: Drop uclass_find_device_by_phandle() with of-platdataSimon Glass
At present this function is included in the build but with of-platdata it only services to produce a confusing link error complaining about a call to dev_read_u32_default().

2021-03-23pci: layerscape: Change to allocate zeroed memery for struct ls_pcieHou Zhiqiang
As on some incipient Layerscape platforms (LS1043A series) there isn't separate PF control register block, these registers reside in the LUT register block, so when the driver detected there isn't 'ctrl', it will assign the 'lut' address to the ls_pcie->ctrl. The current code allocate memory for the struct ls_pcie with random contents, this can result in skipping to assign the ls_pcie->ctrl with the 'lut' address, then further crash with the incorrect address.

2021-03-19nvme: Always invalidate whole cqes[] arrayAndre Przywara
At the moment nvme_read_completion_status() tries to invalidate a single member of the cqes[] array, which is shady as just a single entry is not cache line aligned. The structure is dictated by hardware, and with 16 bytes is smaller than any cache line we usually deal with. Also multiple entries need to be consecutive in memory, so we can't pad them to cover a whole cache line. As a consequence we can only always invalidate all of them - U-Boot just uses two of them anyway. This is fine, as they are only ever read by the CPU (apart from the initial zeroing), so they can't become dirty. Make this obvious by always invalidating the whole array, regardless of the entry number we are about to read. Also blow up the allocation size to cover whole cache lines, to avoid other heap allocations to sneak in.
