2022-10-31FWU: Add support for the FWU Multi Bank Update featureSughosh Ganu1-0/+2
The FWU Multi Bank Update feature supports updating firmware images to one of multiple sets(also called banks) of images. The firmware images are clubbed together in banks, with the system booting images from the active bank. Information on the images such as which bank they belong to is stored as part of the metadata structure, which is stored on the same storage media as the firmware images on a dedicated partition. At the time of update, the metadata is read to identify the bank to which the images need to be flashed(update bank). On a successful update, the metadata is modified to set the updated bank as active bank to subsequently boot from.

2021-10-31iommu: Add IOMMU uclassMark Kettenis1-0/+2
This uclass is intended to manage IOMMUs on systems where the IOMMUs are not in bypass mode by default. In that case U-Boot cannot ignore the IOMMUs if it wants to use devices that need to do DMA and sit behind such an IOMMU. This initial IOMMU uclass implementation does not implement and device ops and is intended for IOMMUs that have a bypass mode that does not require address translation. Support for IOMMUs that do require address translation is planned and device ops will be defined when support for such IOMMUs will be added.

2020-11-06board: Rename uclass to sysinfoSimon Glass1-2/+2
This uclass is intended to provide a way to obtain information about a U-Boot board. But the concept of a U-Boot 'board' is the whole system, not just one circuit board, meaning that 'board' is something of a misnomer for this uclass. In addition, the name 'board' is a bit overused in U-Boot and we want to use the same uclass to provide SMBIOS information. The obvious name is 'system' but that is so vague as to be meaningless. Use 'sysinfo' instead, since this uclass is aimed at providing information on the system. Rename everything accordingly. Note: Due to the patch delta caused by the symbol renames, this patch shows some renamed files as being deleted in one place and created in another.

2019-04-11soc: ti: k3: add navss ringacc driverGrygorii Strashko1-0/+2
The Ring Accelerator (RINGACC or RA) provides hardware acceleration to enable straightforward passing of work between a producer and a consumer. There is one RINGACC module per NAVSS on TI AM65x SoCs. The RINGACC converts constant-address read and write accesses to equivalent read or write accesses to a circular data structure in memory. The RINGACC eliminates the need for each DMA controller which needs to access ring elements from having to know the current state of the ring (base address, current offset). The DMA controller performs a read or write access to a specific address range (which maps to the source interface on the RINGACC) and the RINGACC replaces the address for the transaction with a new address which corresponds to the head or tail element of the ring (head for reads, tail for writes). Since the RINGACC maintains the state, multiple DMA controllers or channels are allowed to coherently share the same rings as applicable. The RINGACC is able to place data which is destined towards software into cached memory directly. Supported ring modes: - Ring Mode - Messaging Mode - Credentials Mode - Queue Manager Mode TI-SCI integration: Texas Instrument's System Control Interface (TI-SCI) Message Protocol now has control over Ringacc module resources management (RM) and Rings configuration. The Ringacc driver manages Rings allocation by itself now and requests TI-SCI firmware to allocate and configure specific Rings only. It's done this way because, Linux driver implements two stage Rings allocation and configuration (allocate ring and configure ring) while TI-SCI Message Protocol supports only one combined operation (allocate+configure).
