Set S3C_FB_MAX_WIN to 5, which is the maximum that any of the current hardware can do and the cost of having it set to this for all is minimal (at least for the platform data case), then always leave this as the maximum for the systems supported.

2010-05-18S3C: DMA: Add api driver for PL330Jassi Brar
Latest Samsung SoCs have one or more PL330 as their DMACs. This patch implements the S3C DMA API for PL330 core driver. The design has been kept as generic as possible while keeping effort to add support for new SoCs to the minimum possible level. Some of the salient features of this driver are:- o Automatic scheduling of client requests onto DMAC if more than one DMAC can reach the peripheral. Factors, such as current load and number of exclusive but inactive peripherals that are supported by the DMAC, are used to decide suitability of a DMAC for a particular client. o CIRCULAR buffer option is supported. o The driver scales transparently with the number of DMACs and total peripherals in the platform, since all peripherals are added to the peripheral pool and DMACs to the controller pool. For most conservative use of memory, smallest driver size and best performance, we don't employ legacy data structures of the S3C DMA API. That should not have any affect since those data structures are completely invisible to the DMA clients.

2010-05-17net: Add ndo_{set|get}_vf_port support for enic dynamic vnicsScott Feldman
Add enic ndo_{set|get}_vf_port ops to support setting/getting port-profile for enic dynamic devices. Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface.

2010-05-17net: Add netlink support for virtual port management (was iovnl)Scott Feldman
Add new netdev ops ndo_{set|get}_vf_port to allow setting of port-profile on a netdev interface. Extends netlink socket RTM_SETLINK/ RTM_GETLINK with two new sub msgs called IFLA_VF_PORTS and IFLA_PORT_SELF (added to end of IFLA_cmd list). These are both nested atrtibutes using this layout: [IFLA_NUM_VF] [IFLA_VF_PORTS] [IFLA_VF_PORT] [IFLA_PORT_*], ... [IFLA_VF_PORT] [IFLA_PORT_*], ... ... [IFLA_PORT_SELF] [IFLA_PORT_*], ... These attributes are design to be set and get symmetrically. VF_PORTS is a list of VF_PORTs, one for each VF, when dealing with an SR-IOV device. PORT_SELF is for the PF of the SR-IOV device, in case it wants to also have a port-profile, or for the case where the VF==PF, like in enic patch 2/2 of this patch set. A port-profile is used to configure/enable the external switch virtual port backing the netdev interface, not to configure the host-facing side of the netdev. A port-profile is an identifier known to the switch. How port- profiles are installed on the switch or how available port-profiles are made know to the host is outside the scope of this patch. There are two types of port-profiles specs in the netlink msg. The first spec is for 802.1Qbg (pre-)standard, VDP protocol. The second spec is for devices that run a similar protocol as VDP but in firmware, thus hiding the protocol details. In either case, the specs have much in common and makes sense to define the netlink msg as the union of the two specs. For example, both specs have a notition of associating/deassociating a port-profile. And both specs require some information from the hypervisor manager, such as client port instance ID. The general flow is the port-profile is applied to a host netdev interface using RTM_SETLINK, the receiver of the RTM_SETLINK msg communicates with the switch, and the switch virtual port backing the host netdev interface is configured/enabled based on the settings defined by the port-profile. What those settings comprise, and how those settings are managed is again outside the scope of this patch, since this patch only deals with the first step in the flow.
