Some config symbols are found in *almost* every _defconfig file for
Allwinner boards, because those options are actually a platform choice,
and not a per-board decision.
Some of these options are older, some have recently been added.
Move those options to be set for all Allwinner boards in their
respective Kconfig files.
The rationales are as follows:
- NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of
address space only, starting at 1 GB. So it's always one bank.
- SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC
accesses, we don't care about filesystems or partitions in there, so
there is no need to define those symbols at all.
- USE_PREBOOT: We start USB early when a keyboard is configured, using the
preboot env variable, so we need to set this variable.
- SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this
symbol to be set (according to 8d8ee47e03).
- SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa5,
specifying this reduces the latency of the USB keyboard handling, so
this was formerly enabled in config headers for all Allwinner boards.

|
|
Universal Serial Bus (USB) is a specification for a serial bus
|
|
subsystem which offers higher speeds and more features than the
|
|
traditional PC serial port. The bus supplies power to peripherals
|
|
and allows for hot swapping. Up to 127 USB peripherals can be
|
|
connected to a single USB host in a tree structure.
|
|
|
|
The USB host is the root of the tree, the peripherals are the
|
|
leaves and the inner nodes are special USB devices called hubs.
|
|
Most PCs now have USB host ports, used to connect peripherals
|
|
such as scanners, keyboards, mice, modems, cameras, disks,
|
|
flash memory, network links, and printers to the PC.
|
|
|
|
Say Y here if your device has an USB port, either host, peripheral or
|
|
dual-role.
|
|
|
|
For an USB host port, you then need to say Y to at least one of the
|
|
Host Controller Driver (HCD) options below. Choose a USB 1.1
|
|
controller, such as "UHCI HCD support" or "OHCI HCD support",
|
|
and "EHCI HCD (USB 2.0) support" except for older systems that
|
|
do not have USB 2.0 support. It doesn't normally hurt to select
|
|
them all if you are not certain.
|
|
|
|
If your system has a device-side USB port, used in the peripheral
|
|
side of the USB protocol, see the "USB Gadget" framework instead.
|
|
|
|
After choosing your HCD, then select drivers for the USB peripherals
|
|
you'll be using. You may want to check out the information provided
|
|
in <file:Documentation/usb/> and especially the links given in
|
|
<file:Documentation/usb/usb-help.txt>.

Enable driver model for USB. The USB interface is then implemented

by the USB uclass. Multiple USB controllers of different types

(XHCI, EHCI) can be attached and used. The 'usb' command works as

normal. OCHI is not supported at present.

Much of the code is shared but with this option enabled the USB
|

uclass takes care of device enumeration. USB devices can be

declared with the U_BOOT_USB_DEVICE() macro and will be
|
|
automatically probed when found on the bus.
